I am at the end of my rope and have actually put my 650L motor back to stock piston and cam. I had installed a 10.5 to 1 and a stage 1 hot cam...I could not reliably get the motor to crank over...it would start...but groaned heavily...anybody else had a problem with starting after piston and cam...?

It is not timed right. You are atleast one tooth off.

Get the manual and follow it step by step. Should start fine with the stock carb, mine did.
