Ok, some of you have already read about some of my problems since my recent rebuild of my 302 and carb by a shady mechanic shop. The repair shop had done many thing wrong putting the motor back into the car (disconnected vac lines, used old plug wires which were damaged, carb wasn’t tuned correctly, timing was way off, etc….it was a nightmare). Here are my issues at this point: 1) The car starts ok but has some random misfiring 2) Surging under light throttle 3) Random rpm fluctuations, especially noticed around 1500 RPM. 4) Car accelerates good (not sure if it could be better since rebuild) 5) Idle is rough, idles better when giving it a little gas 6) When in park, if you run thru the RPMs, it gets very rough between 1200-3500 RPM, doesn’t seem quite as rough under load or while accelerating. 7) Car backfires when letting off the accelerator while at higher speeds on highway…not too concerned but thought I’d mention it anyway. 8) When manually applying throttle to the carb, you can feel and barely hear what sounds almost like a growling sound from the carb. Not sure if this is common from the metering of the fuel/air but it seemed odd. A different mechanic shop said he thought it was the carb being clogged by not being cleaned properly when the rebuild took place or that something made it past my filter. I plan on getting a compression check and leak down test performed too, but I was wondering if you all thought my problems could all be traced to simply a clogged passage in my carb.
I picked up some guitar string yesterday to clean out some of the small passages. These work great because they're strong and flexible and some for the the passages large enough, the larger wound strings really scrub them well. I particularly like using these more than just copper wire because I've had copper wire break off before from bend fatique and that was a pain to get out. Guitar string is pretty durable stuff. I hope this fixes my issues.
