I got a new truck and have been trying to get it running. The situation is i starts and will only run for about 5 secs then shuts off. It has what i think is an autolite 2100 2 bbl. It came with an electric choke that was not hooked up, so my first step was to wire that thing up. No luck. Next I pulled the carb and went through it. I put it back on and it ran for about 5 mins this time. Once the choke plate was fully open it stalled again. Then after that it was back to usual, I start it and it stops running within 5 secs.Even if I keep the gas throttled it will stall out. I'm wondering if maybe its getting to much fuel? My next step today will be to check the timing if I can get it to run long enough to verify that. Also thinking that since I dont truly know how long the truck sat I should maybe drain the tank and start with fresh gas. This has got me stumped. Kind of new to the carb thing so I can really use some help on this one. I'm use to diesels, because thats what I work on at work so not much carb experience but both my cars are helping me out with that. I hope some day I will be able to answer these questions for someone in my shoes.
