Ok guys, ive got thid 86 rolla 4a-lc that ive replaced just about everything under the hood i can unbolt and it still wont run right !! I just replaced the carb with a rebuilt one and thought that it would cure my probs and while it is running a bit better, it is still missing and hesitating at low speeds when it warms up. The choke is opening , i replaced the fuel filter and most everything i can think of. any suggestions ?? Oh, when it is cold it idles and accelerates fine.

If you haven't seen my posts... I've been struggling with an 88 fx 4a lc. It sat for 6 years and I've almost got it right. Recently I stopped messing with the carb. It would quit running for lack of fuel. Spray start would get it to run. So I finnaly realized it was the feed from the tank that was not working. Yeah I had fuel in the filter but the pump (new) couldn't suck it because of blockage further back! I had the tank down once already and I thought I cleared the line well enough. The other day I dropped the tank again and the pipe that draws fuel through the strainer has an s shaped bend where rust collected. so I tried to clear it again. Last time I cleared it a bit of wire broke off and stayed inside there. I was using a drill with a double strand of twisted .032 safety wire. If the vent line is clogged that will creat a vapor lock also. Try running your car from an alternate fuel system. From the filter back run a hose into a gas can. I should have replaced all the flexible hose sections the first time. Live and learn.
