Rebuilt Raptor Wont Stay Running

(1/2) > >>

tcoop212:
I rebuilt an 02 raptor 660, it runs for a while (20-30 seconds) and then dies. It seems that It is running out of gas, because before it dies it revs up  very high. I pulled the petock valve out of the tank and checked the filters, and they were clean, I opened up the carb and cleaned all the jets and stuff. It seems that right after I did this it was running longer. So maybe I need to do this again. Could it be the air mixture being off? When it is running it is rough sounding and backfires a lot (shooting flames). Thanks for any input.

Peelz:
could be a problem with floats?

Krandall:
revving up REALLY high and dieing right away sounds like a symptom of an air leak, a very lean scenario

oh oh.... well said Krandall.

on that note: check your intake boot for tight seal. 660's had issues with that. mine had zipties keeping it on. and make sure youre getting enough gas in both bowls.

Im almost sure that it is just running out in the carb, after it revs up and dies it wont restart for a few minutes (until the carb fills back up??)
