Hey, this is my first post, but I've been reading the forum for a while. dmilzoff is the other driver of the car, you may have seen him post before, he's fairly new also. We just had new headers put on the car. The carbs (weber-48's i believe) have been cleaned and tuned. Its an 82 911 engine by the way.
It used to backfire a lot, before we had the headers replaced. Turned out there were a few episodes of rust on the old headers which caused holes and I know that can cause backfiring. But I'm sure there are no holes now because of the new pipes. (IMG:style_emoticons/default/biggrin.gif) The car still backfires once in a while, so I assume there is some sort of dirt getting into the carbs still. A friend suggested that the gas tank might be rusty inside and that the fuel filter isn't grabbing all the rust. What do you think (IMG:style_emoticons/default/confused24.gif) ? The filter was installed last year, but very low miles have been put on the car since then. Think changing the filter will solve the few backfires here and there? Or is it more involved? Frank |

When it backfires, which isn't very often at all, its on deceleration. I guess a little bit of backfire from the a carburated car is not abnormal. In the case of there being rust in the gas tank. Could that cause backfiring? What kind of steps can I take to check to see if its rusty in there and how can I get a rusty tank cleaned?
