Last month I took the 406 out of my 81 to take care of the timing chain cover leak. Easy fix. New cover, gasket and I sprung for a new pan gasket. Went together without a single issue and its all back in the car and ready to go.
Now to go back a bit. Two days before I pulled the motor I wanted to check how much manifold vacuum I had. For some reason the brakes just dont feel right. Factory discs in the front and the big drum setup from Moser in the back. Im 99% sure theyre adjusted right and EVERYTHING for the entire system has been replaced.
So Im cranking the car over and its not kicking. No gas getting into the carb. Im thinking the bowls drained over time. It had been months since it ran last. While I was trying to get it running one of my friends stops buy. Hes not a novice. Hes built multiple cars and he currently is working on a big $$$ Vette besides owning 2 others. He suggests pouring a tiny bit of gas into the carb. I get a cup, dump a few drops in and it started. Ran for less then 10 seconds. He tells me to work the key and he'll pour the gas in. Mind you, this is something Ive NEVER really done. I know. The gas could/should have been put into the tube sticking out of the carb or at least sprayed in and not poured. Well, that didnt happen. Water under the bridge at this point.
Im sure anyone that works on motors knows what happened. HUGE backfire. Flame shot up. It wasnt good.
So, get back to now. Yesterday I hooked up the 6AL with some butt connectors to make sure I could get it running. Cranked it for a few minutes, Started getting gas in the carb. As soon as it started it ran like crap. Rough as hell. Cant idle right. It feels like its running on 4 cylinders. Never touched the distributor or wires. Had the Holley 750HP sitting on the bench covered the whole time. Put a fresh set of plugs after I put the headers back on. Im stumped. Fresh gas.
Maybe the power valve popped from the backfire ? What do you guys think ? And please, no butt ripping about the gas. I know, the other guy knows, it was a really stupid thing to do.
