Hey folks, got a new one (well at least for posting, been working on it for at least 2 months) 02 660 no start. came in with a cheap chinese carb on it and was barely running, swapped to oem carb that the customer still had and drove it from shop storage to shop floor ( still ran poorly) installed a new spark plug and all of a sudden, no start. swapped back to old plug and no start. checked valves and timing, timing was off a tad bit, reset timing and valves, had verified by a second tech, still no start. this thing wont even pop off on starting fluid. compression checkes at 130 psi. Any ideas?
