Been sorting out some gremlins in my 84 K5. It seems when it rains it pours, my truck was running fine and then all of a sudden from electrical issues to carb out of adjustment within a week, not sure wth happened.
Anyways, didnt see anything with the electrical, ill be pulling all my handy work wiring out and going with bare basic add-on electronics.
Anyways, got to re-tuning my 570cfm street avenger carb and wasnt able to get the choke set, had the choke cap changed and still not sure, gets too warm around here to really mess with the choke much, once the truck is started its hard to get choke to kick. but ended up doing some A/F adjustments and decided to put a timing light on my truck, with the vacuum advanced disco'd, I had 12 degrees of timing, factory says 4, so not sure what that was all about. My buddy has a better ear then I and we went for a drive and he heard pinging, so we came back set the timing at 8 degrees advanced, heard ping but not as bad, so I settled for 5degrees, one off factory, Truck runs fine, so after all the tuning, I have a vacuum gauge mounted in engine bay to tune carb, now its reading 18hg, which is pretty good from what I hear, its holding steady no bouncing or waving or moving.
So anyways, thought id share.
