ok i just put a jd 416 piston and a hotcams stage 2 cam a rev limiter and advanced the timing 6 degrees ok when i first fired it up it ran great i rode it for about 20 minutes then later that evening i went to fire it up and it was back firering not wanting to run now it does that every time until i ride it for about a 1/2 hour then it runs exelent the rest of the time i keep wanting to back to the carbrator but the jetting is right on the money so could it be the timing ? or what ?
