Hello. Going along with what many of you suggested, I took the carbs off and rebuilt them. There was alot of varnish inside and a considerable amount of gook on the bottom. I cleaned everything out with carb cleaner and put them back on the car. With starting fluid the car started almost right up and ran for about 5 min perfectly, with me holding it at about 1300 rpm. After this run, it started right up everytime even after waiting 10 min (without starting fluid), sometimes didnt run very smoothly and sometimes backfired but caught itself 9 out of 10 times and kept going. At one point I got the car to for about 15 seconds then it shut off, the idle was a little below 500 rpm which is too low according to my carb rebuild book. So yesterday(when all this happened) I was very pleased with my progress and I thought I had finally crossed a huge threshold in this project and now all it needed was fine tuning. But then today came along. Got home from school and couldnt wait to get it running and try to tune it up some to get it to atleast idle. But, it didnt start as easily. It took a few tries to get it going and when it ran, it didnt run quite as long and not as smooth. The only good thing I saw was that it really tried to start without any encouragement from the gas pedal. I got very frustrated and the battery was running out of juice so I pushed it back into the garage and took the battery out for a charging. I looked at the float bowls and the back carb was not as full as the front carb. When I rebuilt the carbs I set the float levels as the manual suggested and gas is free to flow into both floats.I assume the lack of gas in the back float is what is causing the engine to shut off but any ideas of what is causing this? and, is it really the only problem here or is the backfiring coming from some timing issue or what? Any help you can give me is much appreciated. The Cleveland winter is fast approaching, sadly, and I want to at least take the Healey around the block. Thanks Again, Andrew
