All around problems :(
So I made a post a while ago when I tried to switch to a different carb with a better choke and ended up going back to the old one anyway. Well now that venerable 2150 is giving me troubles. A lot has changed since I last posted, I finally decided to fix the burnt valve (which turned out to be a completely destroyed valve seat and ruined cylinder head and two bent pushrods, so I got a new one of everything broken and put everything back together with some help from a friend of mine, very knowledgeable guy. Once everything was back together I started the car after a little hassle and work it was running really rich so I would start it then turn the fuel mixture screws down until it smelled ok and ran good without throttle bog. Then whenever I would shut it off it wouldn't start so I would have to back the fuel screws back out to start it, then one time I got it started everything was running good and there was a miss and then the engine kept running, I decided to give it a little rev and as soon as I touched the gas the car died. (BTW when the car would start the fuel screws were almost falling out of the carb. So after it crapped out I pulled the carb and did some tinkering making sure all the parts were the correct ones ( for a while I swapped in some parts from one of the three 2100s I have lying around) after that I put the carb back on still wouldn't start. A few days later I had some more time to work on it and I found that the check ball was missing so I grabbed that out of one of the other carbs, still no starting. The entire time it's had a little backfiring going on not often usually when I let off the key and throttle a big fireball comes out of the carb. Also every time I try to start it sputters and almost catches but as soon as I let off the key it doesn't run, how ever sometimes when I have the pedal to the floor it fires a little really slow but as soon as I lift it dies, this happens regardless of fuel screw position. Also for turning the screws I always start at 1 and 1/2 turns out from all the way in, which seems like the norm for a starting point. This carb is on top of a 351W completely stock besides MSD Blaster II and 100 amp alternator. Any and all help/ideas are appreciated.
