My son is running a KT100 with a 4 hole can. At the last race he started having an issue with gas mist coming out of the air box (or at least that's what I think). Enough so that the kart side pod, front of the motor and his suit were covered. We run an oiled filter in the air box, there does not appear to be excess gas inside. I did make one change before his race by removing the fuel filter. We have had 2 race days and 1 practice day since the carb was rebuilt, pop off at 10psi. Any ideas as to why this happening?
