[quote]ORIGINAL: Twin Star I picked up a MTD/Ryobi engine in a box and Id like to put it together but some of the parts were missing. Does any body have a good piston and rod assembly and reed and reed stop they could spare for a very reasonable price? [/quote] I might have a reed valve and back plate. I'm sure none of the pistons and rods I have are any good. diceco

[quote]combatpilot said: ........the weight savings just isnt enough to be a concern. granted you are losing the flywheel and coil but you must add back in the box and all the works ie sensor, and a fairly large battery. so the weight savings really isnt much. [/quote] I use a single cell 1800 mah LiPoly battery to power my CHXL (essentially an RCEXL) ignition. It weighs a fraction of the weight of a NIXX battery and it runs fine at the lower voltage. Check out the CH ignition web site for tests that Bill has done on ignition function vs. supply battery voltage. Except in rare occasions you can't hand start an engine with stock ignition.

RE: another darn ryobi post (ryobi performance modification, analysis and comparison)
Sounds like you got'r covered Jim.... If you're interested in doing some transfer port entrance smoothing ala post No 145 I'd be real curious whether it's worth the effort. When I did mine I just knew the stock blunt entrance to the transfer ports couldn't be good for the flow coefficient but I didn't actually measure the difference before and after the mods. diceco
