The situation is exactly the same but the sound was different. This was a pop like gun fire. But I was barley in the gas pulling a hill and gave it a little more the rpms started climbing and it was a pop pop I let out and it went away. It does the same thing if I hammer it from a dead stop. I'll make some video tomorrow
Damn im just missing all my diagnostica today. I thought backfire was to rich. Is that if its backfiring thru the carbs? It will back fire thru the pipes if you rev it up while parked too. Do I need to richen it? I thought the bog was coming from it being to rich but maybe its too lean?
Light ping , sure does!.
A bog is almost always a lean condition. I'm almost inclined to think maybe you have a couple of wires crossed......on your engine I mean. lol Double check it.
There is a local pocket rocket car around here that backfires whenever the punk lets off the throttle. Imagine being in a convertible with your ear inline with the tail pipe. About went deaf the last time it happened.
I'll check it out tomorrow I just pulled the dissy out so I could have crossed two. It ran alot better I messed with it.
Yes i took it apart to set my mechanical advance this is the first time out since then. I'll check the gap tomorrow too thanks for the idea!
Dang I hope its not that. Lol
YIKES! Ouch....
Yea that would suck.
I just went through that, well, Thankfully, not that part... Never heard anything. But timing was way jacked up. Ran like a raped ape... Is it possible that headers would mask that?
Im running full exhaust its not real loud. Not as loud as yours lol yours sounds like its sucking in the ozone layer lol
I gave up running open headers years ago! Lol! 2 1/4 going to 20 year old turbo muffs ( hmm) with 2" or less out the back. Bought 2.5 " pipe and Flowmaster 40s last year. Wanna go from them to 2.25" out the back.... not my post, just trying to learn. I'm in Full Belief though, that without help from the Brothers here, I would have popped something.. . Ugh.
I think mine is 2.25 all the way to the back. But yea on the 20yo turbos lol gonna replace the whole system eventually ill probably go 2.5 all the way back might just do it straight all the way back 2.5 inches I don't think it will be "too loud" lol
You know, in another post last, week, I didn't comment on ( but wanted to, phone issues) when you described your Auto Shop teacher " laying hands " on the valve covers, it made me think.... my valves were not clattering, but had an Odd " grinding "sound... hope I didn't trash the seats.....
You get one clack with hypers if you fix it right away, it'll keep going... for some undetermined amount of time then fail.
Bro, it will sound and perform killer! But if you don't like it too loud, and teeth rattling, there are definitely better noise reduction/ power making muffs than the 40s I chose. Got em for 40 bucks from an exhaust supplier ( local warehouse), in retrospect, wish I had not got em. But I'll run em. Those were what I ran on my old 68 in the early 90s. Lol
My plugs are showing signs of being rich. Extremely black and sooty. But as of now the engine has spent more time idling than driving.
That's right, so reading the plugs is useless right now.
Yea we have discussed that before.
