Chain was replaced recently, Car ran great, last night I was out and it started acting up, runs good @ higher speeds with a little surging going on, but @ lower speeds and @ idle its gotten really bad doing the number I`ve posted above.
Pulled diz. gear looks fine, gap is good. Can`t even get it started now without it backfireing from carb, had to snuff a carb fire. Vac adv. is not connected. rotor is free and snaps back fine. When it was running, but badly, seemed rotating diz. did`nt make any difference? I`m stumped. Could this be carb related? I can get it started but it takes alot of carb opening and once through a few backfires,I can get it going and it sounds good @ higher rpms. Lower throttle the pop, stumble, backfire, die. "In the voice of tweety bird" Haep!~Haep! me! :-? Oh, and pulled plugs, 1467 looked ok and 2358 looked fuel fowled. My mind is jumping all over the place, I think I need to go back to timeing. No way carb is involved if timeing is fluxing back + forth- Jeezsh
Holley 770 St.avenger, only a few years old. Could a power valve be blown? even though they supossedly corrected this problem? I guess I`ll pull it apart tomorrow and check things over. tomorrow was going to be reserved to work on my welder carb again after 15 r+r`s. when it rains it pours.
Just put on a new $$ balancer when I did the chain back in april?
I hear ya buddy, I`ve been working on my own junk for 35 years and they will stump me for another 35 I suspect. Just by looking at them they look fine. I`m gonna check for any cross contamination of oil/ water, tomorrow. Ran my ecm out to the Zone and it tested fine. I- and my bud, noticed some light tapping from right bank. I guess I should pull cover and see if any pushrods are bent or worn rockers. I`m with ya on the plugs, I guess a spray test around manifold will tell, but hate to run engine in this condition. But would`nt a vacume leak cause the cylinders to run lean instead of rich or fuel fouled?
Yes checked rotor orientation before pulling, remember, car will run decent @ 2 grand or higher, then when I let down off throttle she starts its popping backfireing out right bank exhaust and through carb. seems somethings going on, with the right bank?
I checked under cap looked ok, will inspect closer tomorrow under better light, heck I think I have a new spare too. Going to run the diz. trigger out to be tested also. This car has been garage kept since 97, shes outdoors now, Probably pissed cause an old decrepit dodge has taken her place:-D
Morning all, Yes the thought occured to me, If you look at the pic I posted of the wiper motor, in the back you`ll see a little paint rubbed off the firewall, thats from the boot of that wire, it`s wore a little but not near the wire. Why did Ma design it so close? I`ll do a closer inspection of all wires, but I have em loomed and they should be ok?
Yeah, once I get another couple cups of coffee in me I`m headed out to hit it again. Another thing I noticed, I pulled a vac plug from the back of carb and it had some fuel in it? Maybe normal considering the condition it`s running. I`m gonna look for my other cap, I pulled out my folder, and found my reciept, man, caps a year old allready, and showes I bought 2, So I`ll throw new one on there just to put it out of the equasion. Wish me luck:clock:
