You didn't frinkle with the cam timing did you?If the intake is opening too soon that could cause some spitting from the carb.
I've had my uce ping briefly a couple times in very specific circumstances and it sounded just like the ping of a small japanese four banger.
Pushrods were perfect.Engine was assembled here in India by one of those "mechanics," but when I spoke to him about the engine we even discussed how the timing marks were supposed to be oriented. Haven't opened the timing cover myself to check it out, but since there's no other performance-based additions to the engine I would doubt that's the problem.I retarded the timing a hair. I am still, it seems, unable to clearly differentiate ping from the normal valve noise. Someone else described it as something like the sound of a ball-point pen clicking rapidly, but I'm also thinking that's what my valves sound like at high RPM. What I suspected was ping sounded like a small rattlesnake somewhere on my rockerbox. Not clearly audible unless you were paying particular attention to the engine sound, and although it seemed to stop when you let off throttle, it was very rhythmic. Is this just the sound of my valves?
The gap is good
