Gearheadcurt Posted November 30, 2010 Report Share Posted November 30, 2010 Ok sorry I haven't gotten any pictures up but here is my problem she back fires out the intake going down the road, and at times shuts off at stop lights this is a new problem Idk where to start because of the modifications she has a different intake manifold and a weber 32/36 and a 485 lift cam I also noticed that it is advanced a quite a bit I ran 86 and it started this problem I just put 93 in to see if it was the gas that triggered it Quote Link to comment
Braden Posted November 30, 2010 Report Share Posted November 30, 2010 backfiring out of the carb is a lean condition, check the main jet for debris, also check your mixture. set the timing to 12btdc. run the 93 after all of this, report back. Quote Link to comment
