[QUOTE="TeamBrian, post: 545557, member: 20175"] Engine: 1641, Engle100 cam (SSP's new engine). Dellorto DLRA36 carbs with 115 main, 55 idles, 33p/j, 28mm chokes. Right, my carbs are popping on deceleration, not badly, just now and again. Idle is good and steady, no flat spots on power, no air leaks, no exhaust leaks, timing set correctly, valves correctly set, fuel regulator set to 3.5psi. The spark plugs are brown in colour with a very, very faint hint of white on the tip. Fuel adjustment is wound out 4 turns. Engine doesn't appear to be running hot. Should I wind the fuel adjustment out more or should I be looking at different jets? How are you supposed to adjust the fuel, anyway? Thanks. :D [/QUOTE]
