So Im running the 14cc head and flattop piston .010 in the hole. BP2 cam with 1.3 rocker on intake. Stock carb bored to around .650. Last couple weeks this thing screams early on then falls flat later in race. Not sure if kart is tightening up but think not since it still handles same. Maybe air pressures I dont know. Anyways I was thinking could it be the motor getting too warm? I know guys say they like to run hot but mine seems to like cooler. I dont know what temps are but am just gauging from performance. Outside of motor temps are consistent each time I check even though I know that is not same as combustion chamber temps.
I jetted main up to a 39 from a 38 last weekend. Did not tell any difference nor did I check plug...(was in a hurry). Low side is still at 24. Running Cam 2 leaded fuel. Should I go up yet another to try to cool motor? I think it personally likes lean. Is lowside too high you think?
Wondering if this is consistent with others are running with similar builds or if I should start looking elsewhere. We run like 30-40 laps at a time on 1/10 mile dirt track. No sanctioning.
