Just had the Engine rebuilt having trouble getting it started I've had to use either to get it to start and then keep it at 1/4 throttle to keep it running I think I've got the plug wires in the right place,maybe the timing is still off.I pulled the plug out of number 6 cyl stuck the rod in and brought it up to top dead center on the comp stoke one number 1 cyl I must have some thing else wrong ?????
