I replaced the cam centering the crank line index between the teeth of the cam with the timing mark (looks like a shallow drill hole). When I pulled the rope the old style choke (thumb pull-Push) goes in and out which I figured as a intake valve timing problem.. Where did I go wrong? Or do I have the cam timed 180 out of sync.. :freak: :confused:

line up the mark on cam with mark on crank check your keyway that its not sheared check your valve clearance also

on the cam you will see a little line on or next to one of the teeth. thats the mark you use. f-n-m

Do you happen to know the clearnce for the valves? How do you change clearance if is not enough? New Valve or slowly grind stem of valve to increase clearance? :confused:

im not sure of the specs on your motor but i was told the valve gets peaned over and you can lightly grind it to spec. im sure bugman will know the # you need. f-n-m

Thanks, I found it on another site, my intake and exhaust have a much smaller lash than what is called for at http://www.arcracing.com/cgi-bin/SoftCart.exe/Tech/spec1.htm?L+scstore+yhlp1753+1114273929
