I've been having the same problem with my JP .12 modified. I bought it for the sedan nats in crystal park and it cost me my first two qualifiers with DNS'. Anyways, I changed out to different carbs new and old with the same issues of overheating. Harry Hananouchi tuned my motors and set my clutch and it still did the same thing. I would go out to do some practice laps before the race, come in after 4-5 laps with a temp at 210 F. I then would take another lap and it would go completely flat with no power. Come in to the pits with a astonishing 310 degrees F
. I've talked to other JP users and some of them claimed they had the same issues
. I don't know what to do next which makes this quite frustrating. I have to resort to my 3 year old reliable MR12 TQ racing motor to complete races.
