Backfire and weber tune help
Okay here is the situation. I have a weber on my 258 with no ECM (82 didn't have it). All the emissions stuff is still intact. Original ignition. Mr. Gasket fuel pressure reg.
I am getting a backfire on deceleration from high speeds 45+. The kicker is that if i keep the accelerator depressed slightly it doesn't do it.
Have checked the timing and taken it as high as 12 and as low as 6. Have re-tuned the carb.
Went to O'reily's today and rented their compression tool and going to check that tomorrow night. also picked up a vacuum gauge and going to check for leaks there.
I don't know what else to include. Any thoughts or suggestions?
