Still Learning
Okay, I have a 1985 Ford E-150 van that I have put a 351 with a 4 bbl. Everything was fine until the other day when the van felt like it lost some power. When I stopped at the next light the van ran rough and wanted to stall. I continued on and the problem seemed to go away. Now the problem is when I brake hard or when I turn fast, the engine seems to load down. I'm pretty sure the carburator is the culprit but I'm not sure where to start. Could it be the floats out of adjustment? If so, how do you adjust them?
Any help is appreciated in that this is my primary mode of transportation.
Thanks
Dave

well, something happened "the other day".
may be something stuck in the main fuel jet; or one of the carb sections is loose ans sucks vaccuum as result of acceleration, or float axel got loose, or float is toughing the wall. As result, the engine runs, but might be on the edge of stability. Careful inspection of jets/venturies, fasteners, float/valve, gaskets, carb sections for flatness (do not overthighted them, may bend!!!), sometimes reveals the problem.
check out if it runs better when cold or hot (so to check if the mixture now is too rich or too lean)

Okay...Got the problem with the carb fixed. Seemed the floats were way out of wack.
Now the next problem. The van will run all day long at 60-65 but getting to that speed takes a while. At hi RPM's, it seems to have power, but at lower RPM's it seems to bog down and sometimes even has blow back thru the carb. Is this timing, too little fuel when needed or too much fuel when needed?
