IT doesn't backfire but when I'm slowing down for a traffic light the exhaust does pop but it's not loud, you know? :) Surging was the right word I think! Haha. Yeah, doesn't happen going up hill. I'm pretty sure it happens even if it's at operating temperature, but will double check today as I am going down the hill at about 10 o'clock and car should be pretty warm.
Manual choke.
Well I did post a thread about my dizzy leaking, maybe that has something to do with the ignition? Haha.
My vacuum lines are all over the place, so that could be it as well. I had one look at that vacuum hose pic and said "forget it". Haha. I'll try again today!
Cheers guys.
