macauto 123123 have you figured out you problem yet. im telling ya theres a good chance you got a crank case leak. over here in n,b canada and i felt like chopping up my walker jet untill i learned how important it is not to have ANY LEAK AT ALL in a crank. it makes the motor heat up, and heat is the number 1 piston,cylinder and ring destroyer. im telling ya it took me 3 motor jobs to figure this out.
