RE: another darn ryobi post (ryobi performance modification, analysis and comparison)
with my combination I am running more compression than the newer motors I believe, but not sure how the fuel will effect it till I try some tests of different fuels. I am running a WALBRO WT 29A carb right now I am not sure of its size. Is there a cahart or a web site with specifics on Walbro carbs by part #? I also have a Walbro 610 I want to try it has a 34 stamped in the venturi.
