i have one of these engines in mine ,,its a right beast,was using a jp1 on it tho which seemed to restrict it a little ,just waiting for my 810 bigbore pipe woohoo.
had 1 gallon of 25% through it and nearly finished a gallon of 30% ..holds its tune and no matter how long i use it for the tick over is solid .still on the same plug.(i took the plug out that came with it the day i got it and replaced it with a 100 odonnels plug)the 100 plug has been upgraded now to the 102.
was a little worried at first about how far i had to wind the lsn in to stop it from being so rich ,so far 1.5 turns out ,hardly had to touch the high speed needle ,,maybe half a turn in from standard. never goes over 94c ,not even after 11 mins of run time. bigger or second tank is a must . was getting just over 6 mins before.
