Ok so the 55 Buick super has correct timing, all electrical checks out, car runs pretty decent, thinking that I get junk in the carb from time to time thats causing the issue. Im going to put a fuel filter before pump and after pump until I can find a replacement tank. Any other thoughts??
Usually happens when I put my foot in the pedal, seems to bog down, and sometime on the freeway above 60-70 mph, off and on it will run like a champ down the highway and then some days it will barely run, took the pump apart twice and the carb twice pushed air back thru the tank, re timed, re adjusted carb. Looked at accelerator pump it appears ok, the only thing I can think is junk is getting stuck in carb.
Forgive me, I don't know much of anything about the '55 fuel system. Does the '55 sender in the tank have some sort of screen to prevent tank debris from moving upstream? I ask because if so, you might've cleared it temporarily with the shot of compressed air, but it could become blocked again later. Devon
not sure what you mean?? The tank was cleaned at radiator shop, and had sealer installed and then put in sending unit. Does that make sense?
Makes perfect sense. In that case, I'd rule out tank contamination and the possibility of a clogged pickup screen, so we should be able to move forward in the fuel system in trying to figure things out. There are still some other possibilities, like something else got into the tank, or the tank sealer had poor adhesion and is gumming up the works from the inside. Devon
About ten yras ago. Mine got a clogged fuel line. The most noticeable sympton was; it ran hot. I mean; really, HOT. The coolant was'nt hot . But, the heads were HOT!!!
You said "retimed" was the timing off? Slack in the chain can make an engine run off from time to time.
Unless there is something mechanically wrong inside the distributor such as a sticking centrifugal or vacuum advance, once the ignition timing is (properly) set, it should not cause an intermittant problem. If you know for a fact that the base timing was set correctly, I would rule that out as a problem. A sloppy timing chain will hurt performance, but it will not be intermittant.
