DLE30!
Here are the first released pictures of the new 30cc engine from DLE that will be out mid July. Kind of cute, kind of different, hope it lives up to the spec sheet! Still no word on price yet though.

RE: Checkvalve replacement on Walbro wj-71
So, no one here has taken a WJ-71 completely apart or even knows that the high speed nozzle is the high speed jet and is easily replaceable? Close the choke valve and use a drift to drive the high speed nozzle into the bore of the carburetor, open the choke valve and remove it. Install the new one the same way and the same direction, no Loctite required. http://www.mowtownusa.com/Walbro-Carburetor-Part-86-657-1-Nozzle-Assyseat_p_94276.html

RE: MT70CC TWIN
I don't understand why this brand is even talked about anymore. What most if not all of you don't seem to understand is that there is NO MT engine manufactory, there never has been. MT engines is Tomy Shen, that's all, one person. He buys surplus wholesale scooter parts, contracts with job shops to make odds and ends, contracts assembly labor with XYZ or the local elementary school whichever is cheaper. Everyone is paid by the piece so parts count is what's important not whether it runs or not. Tomy almost never sees the finished product before it's shipped to the customer, he definitely never sees it run before it's shipped to the customer. When Tomy doesn't pay his suppliers or labor, they cut him off so he can't buy the parts to build engines anymore. Guess what happens then....NEW CRANKCASE, NEW CRANKSHAFT, NEW ENGINE MODEL, new suppliers, incompatible parts with the older models, can't get the parts for the older models because they "don't make them anymore" which is partly true because they won't make them anymore for Tomy because he owes them money. New MT76 twin, laughable. It's a shame, wish it weren't so, but it's true.

RE: Walbro Carb for DLE30
[quote]ORIGINAL: Rocketman_ For the experts, After you've gained experience from repairing many engines and researching manufacturer's numbers you know which marking on the carb is the correct model number. How can the rest of us tell at a glance which is the correct "WT" number? The numbers in the picture are WT837 and 759. [/quote] On WT and WA carbs, If there is a set of numbers to the right and a set under the WT/WA, the model number is ALWAYS under the WT/WA. The number to the right is a production run number. Walbro carbs have been coming with the engraved model numbers for a couple years now. It may be limited to certain manufactories, like China and Mexico. The carb in your picture is a WT-759, a very good carb for 25cc-35cc engines

RE: Walbro Carb for DLE30
[quote]ORIGINAL: Antique What difference does it make, all WA and WT carbs use the same rebuild kit... All real walbros have a cast number in the venturi, the number is the venturi size in 64ths... Most any carb with the same venturi size will work.... Flame away [8|] [/quote] IF one is an experienced and knowledgable engine person and has done the research and testing to know the different characteristics and features of certain Walbro models, it makes a BIG difference, all WT/WA carbs were not created equal. Very few people here meet these qualifications, none are engine retailers. I doubt I needed to tell you that.

RE: Walbro Carb for DLE30
The 878 is not the Walbro model #, what you have there is a WT-718-1 with a broken off inlet nipple. The 878 means nothing.

There is no such animal, WT-878 does not exist. Use the one I recommended, WT-759, they work very well and are easy to find.

RE: Walbro for DLE20
John, Tilting an engine mounting position did nothing to help me or the factory, it was not a new concept. It was fine if all you wanted to fly was a test stand or fly your plane without a cowl. I didn't ridicule you for your videos and for you to imply that I owed you something for that is what I took issue with. The fact is, it didn't work for the vast majority of applications. Myself, and others, were working on changing the parts of the engine that caused the problem, not put a band aid on it, we were successful in a relatively short period of time. I don't think the factory should have charged for the new back plate but I had no control over that. FYI, to this date I've never stocked or have even purchased a single ring from Frank Bowman, nor have I ever used an engine with one of his rings, never needed to. His rings are no doubt very good and if I ever have the need I wouldn't hesitate to purchase and use them. His work with piston rings is engine development. Do what you wish the parts I sent you, I don't care, you didn't pay for them or the ignition I warrantied for you even though you didn't buy your engine from me. You can't say I haven't taken care of my side of the street.

Don't know who you're referring about that helped me with anything regarding DLE engine development, seems to me it was the other way around. Besides myself, there was only one person that was ever actively engaged with me in any kind of development on DLE engines, he did it for $ then got his panties all in a bunch when what I told him would happen came to fruition. Taking video of flip starting an engine mounted to a stick in the back yard isn't what I would call engine development. The DLE20/30 ignition timing issue has been explained in detail multiple times in their perspective threads. Walbro carb equivalents for the DLE20/30 are WT793 for the 20, WT759 for the 30.

RE: Tired Old Man and Jody
Some very hilarious and truthful posts here by those that get it, the rest are clueless which is not surprising. For what it's worth, I left this site first in disgust of empty and thoughtless attitudes, Pat followed soon after. Too many here these days have the frame of mind they are at the drive up window of RC gas engine information, that's just plain laziness. Pat and I both grew up in a time and place where it was irresponsible to not at least make an effort to ask an educated question. My father taught me to look first then cross the street, doing it the other way around could at times bring undesirable consequences. Many here would not understand that, they would just jump out into the street and feel personally attacked when a car hit them. I won't speak for Pat but as for myself, Steve and Pe hit the nails on the head. I'm tired of dealing with people that don't view or approach the hobby the same way I did when I started over 40 years ago. It's supposed to be fun and a learning experience. The best way to learn is do things....on your own! Stopping into a website forum and shooting of a thoughtless question for a quick answer is not learning. Think back to school, teachers give students overviews and guidance, it's up to the student to find the details and study them. Then, if there are questions they will be from a perspective of study, not like the student didn't bother to even look in the text book (RTFM!). Remember, there's a test later, for those here it's called flight, failing the test can be expensive. So learning, REAL learning, is important. As was mentioned earlier, we're not dealing with rockets going to the moon. These engines and planes are toys, are VERY simple, they ALL operate the same. Does anyone really think they can come up with a problem or question that hasn't been asked before......umpteen times? But again, it's not the questions, it's the lack of effort exerted to ask an intelligent one. I've been working professionally with two stroke engines of all sizes, fuel types, and configurations for three decades and still counting, they pay me well for it and I love it. Pat, not nearly as long as I but his experience, for the most part, has been extremely intense and detailed. His knowledge of the hobby gas engine (and many other things) is extremely broad scoped and beyond approach. I do miss the days here of actually learning together, when all involved actually got involved, instead of just demanding a fast answer. I doubt either of us will be back here anytime soon, this place needs to grow up a bit ....again. There are only a couple truly knowledgeable engine people left that frequent this forum, I hope for them they do not stay if they find their passion waning. This is my last post on this site for the foreseeable future and I will not log in to check for PMs. For those that can figure it out this site has the capability to send email, I will reply to any and all that care to use that feature. Or we both can be found here; www.teamflyingcircus.com But if you go there, you better have put your big girl panties on.

If I had the chance I would soak up as much information from him I could. I know he has made it much easier for me to care for my gas engines. And I do know about the forum.

RE: JC 28 out of box has very low compression...
[quote]ORIGINAL: derjager Just start the engine and it will seat the piston ring within a few seconds. It will be easier just to use an electric starter on it as it will take a few minutes to start if you have low compression. Most of the issues with JC28 and 30,s are operator error. The engine is very strong and ultra reliable and performs very well. The guys who knock this engine do not know what they are talking about. I am running one of the 28cc in a 20lb LA7 and it performs very well and is so easy to start. If you need any help then please let me know Steve [/quote] Starting the engine will not seat a ring with a .030" end gap, or in a cylinder with its chrome lining falling into the crankcase like the ones he sent for me to evaluate. I would think, if you want to sell hundreds of something, you would send the best you can possibly produce to be evaluated.....on second thought, maybe he did.

RE: Zenoah 20cc ei plug cap problem
Those plug caps are quite a bit easier to pull the high tension lead out of the cap than the larger ones if you're not careful. You can try to push the high tension lead into the cap to see if it will move. Turn the ignition on, look down into the cap and turn the engine over, look for an arc through the silicone boot to the metal shell but if the engine runs fine I doubt there will be any, the arc will jump out past the boot to the shell. You may have just not had it on the plug good, they're a twist lock plug cap, if it's not locked on it will be loose and you may hear an arc.

RE: DLE 20 wont idle
If the idle stop screw has been removed and you're certain the throttle arm is moving fully closed and can't go any further, you may have a loose throttle valve screw, fairly common on the DLE20 carb. The loose screw will allow the throttle valve to move a skew on the throttle shaft and bind in the bore of the carb body not letting it close fully or return to idle.
