Hi guys need your help on where some parts go on an M-10s rebuild (out of a 310-8) of course the P.O. took the engine apart let it age for 5 yrs and then asked me to do the rebuild and then put it all back together. Need help with throttle linkage, PTO reconstruction and what the heck is the small pipe thing with a hole in the middle...… Thanks wheelers...… p.s. running great now Hone job, new piston, rings, head gasket and carb rebuild.
