K so valves are set and same thing. Really hard to start but runs. Seems like its not gettin enough power so when I hook it to the truck and boost it it sounds better but still hard to start. New bat carbs cclean boots not cracked. Coil maybe. Just not enough juice to the plug to get it goin?

01. remove gas tank and tank cover,make sure gas is off and gas line is disconnected

02. remove left side plastic cover of tranny

03. remove both valve covers

04. remove the plastic screw that covers the timing hole and line the flywheel up so the "T" shows, make sure the valves move a little, this means you are on the compression stroke which is where you need to be, if not turn the bolt counter clockwise one turn until the "T" shows again and the valves should have a little play to them

05. take feeler gauge and gap the valves right (.065 MM intake and .17 MM exhaust)

06. check the valve gaps before installing the valve covers once more to be safe

07. install valve covers, after this turn the machine on so you can hear the valves, if they are loose you can still tighten them before the plastic is on, make sure timing hole is covered before turning on

08. install the left side tranny cover

09. install the timing hole screw

10. install gas tank and cover, and connect gas hose

11. and this should be it

K so I had done all that. There's a little notch at like 11 o'clock on the head by the cam gear. I lined the litrle pin up with thatt. It was off one tooth. Then reset the valves. Seems better but not right. Took the carb apart and there a 32 pilot jet!! As per manual said 42.5. Why would someone do that?
