Breeke Posted February 13, 2010 Share Posted February 13, 2010 try timing and tuning the carb back to stock settings. The "how to keep your subaru alive" manual will walk you thru the process. I would start there. -Caleb Link to comment Share on other sites More sharing options...

Yo'J Posted February 13, 2010 Share Posted February 13, 2010 The backfire sounds like a hole in your exhaust. So I was sittin at this coffee shop one snowy day (which is rare here), few years back and I see all these people going down this street that is blocked off, due to the snow, and every one of them slides out of control and hits this poor tree. I sat there for about a half an hour and must have seen 15 cars hit this tree. Some bouncing off it, some using it as an e-brake. So being the fool that I am, I gotta try it! Everyone else was doing it, right!? Well, I must have done something wrong because I never came close to that poor tree. As a matter of fact, I didn't slide once. My little subie just gripped the ground like it was dry. Just a little testimonial to the power of a subie and a good 4wd manual trans. Snow and city dwellers keep the auto industry alive in this town, I'll bet. I have never seen so many accidents and new cars all freshly beat up. I even got rear-ended once going up hill! Anyway....Welcome to the board! Link to comment Share on other sites More sharing options...
doc429 Posted February 13, 2010 Author Share Posted February 13, 2010 An absolute goldmine of info .. wow , the number of replies and directives led me to enough "dope" to start on this problem confidently, and its like 20degF outside this afternoon,,,,, but this is a labor of love,, cold fingers notwithstanding... million thanks doc 429 Cant wait to hear "red" purrrrrrrrrrr......

doc429 Posted February 13, 2010 Author Share Posted February 13, 2010 Addendum; actually 3sisters is a pass on the divide on Interstate 80 not 90 ,cold fingers. I spent nearly an hour under the hood identifying mystery tubes and wires.Now, the backfiring has ceased. One of you guys must have sneaked in here and plugged the 4 main vacuum tubes leading to the air cleaner, while I was in here on the internet.It seems that these create a useless vacuum loop which serves only as a kind of vent from the valve covers, now I know the carb need air to feed the mill,, so any vacuum at the intake would defeat the purpose,, cant fill in all the physics blanks, but reasoning that the leaking exhaust needed to be compensated from somewhere else,, backfires through the tail, so allow extra air at the intake,,,, I read it all here and your help has caused a crushing success,, now the neighbors Envoy will shudder as I top the icy hill leading out from our complex..... many many many thanks one and all!!!
