Believe it or not, to go all the way back to the original post on this thread, I've put new jets in and have gotten the carb to idle pretty decently and drive well for a while, but then I got a pretty similar problem to Scurv's original issue: had to hold the pedal halfway down at all times, gasping down the highway back home at a max of 40 mph.
How I got there is that the heap would run great for a while, then die at stops and refuse to start again. Finally took the air cleaner off immediately after a stop and saw gas streaming into the secondary and puddling on top of the throttle valve. Stopped it right then and there and took the cover off, bent the float arm down a little bit, somehow got the accursed valve assembly back together (that stupid little piece of wire is the cheapest bit of engineering I've seen in some time), and of course by that time enough gas had evaporated that the flooded condition was gone and I was able to get home. Drove it around again, killed it again, flooded it again. "I'll fix your little red wagon," says I to myself, and took a pair of pliers to the lever holding the float and bent it more seriously, probably a few mm. That produced the weak, gasping lean condition I described that seems a little like Scurv's problem. So I think I now have the float level way too low, and when I took the cover off one last time yesterday afternoon I saw that the level did indeed look pretty low.
Does anyone have some pointers on the best way to adjust this float level? I kind of think something less crude than a pair of slip-joint pliers is in order, but I can't find any info on how to adjust the float level on this carb, only that it needs to be done.
A jeep is managed; it is not cured.
