Is my quad posessed? Hello all, brand new here and in dire need of help...I have a 1992 Polaris Trailblazer 250. I bought the thing about 6 months ago and have got to ride it twice since...When I first got it, i tore it down and had it bored .60 plus put in new piston, rings, gaskets, all of it...(plus upped the main jet up to a 150) the first time i started it, it ran like a champ for about 30 minutes and then got hot and died...took it back to shop for inspection and it fried the rings....so replaced them, and went to a 160 jet. Ran fine for a couple days and died. ok, so i bought the oil injection kit, plugged the oil hole in the carb(now premixing 32:1) had the top end checked out again and put in new rings...only now it will start immediately and idle(occasionally revving up a bit on its own), but when u apply throttle, it SLOWLY revs up to speed, smokes like a freight train and backfires...occasionally spitting fuel out of the back of the carb to the airbox. I've cleaned the carb thoroughly, tried every clip position on it, tried many new NGK plugs and still nothing. it will now run without getting hot but that's about it... this thing is a nightmare. Any insight to this would be VERY MUCH appreciated. |
