V-8 flathead problems

[Tony Wheeler]

Any progress on the motor Brian? I'm interested to know where the fault turns out to be.

Thanks for all the responses. Chris, yes this was your Cab 12 F15A - getting dusted off after I got it from you in 2000 (!).
And Tony, I like your comments and they make sense. During this escapade I have changed fuel pumps, used an auxillery tank with fresh gas, checked fuel pump pressure and to day did a good flow test. With help from Stew Robertson we pulled the distributor and all looked good (no reason for the timing to have changed but points could have been bad or something). Two carbs have been tried. Two coils have been tried. No exhaust obstructions.: Still major lack of power over idle speed and no reaction when choke applied or accelerator pump activated. Spark always looked good from coil and at spark plugs. Couldn't see any errant sparking of the cables when it was dark outside.
So tonight I went for a test drive and it works great. Have no idea what solved the problem and I hope my luck continues. The only thing I can say is that tonight was cool, 65 degrees F versus 80 degrees F on previous days although there had been no reason to suspect a coil failing with high temperature. Maybe the rebuild carb just needed some exercise. .......... Brian

Ah yes, that wonderful rebuilt carburetor ... If the former carburetor is re-installed, do the lack of power issues return?

What do you think hold these parts in? Velcro? I wish it was so. I may revert to the original carb if only to eliminate other sources of the problem. If it works right off the bat then there is another unsolved problem.

Maybe all the squirrels hoardings blew out of the muffler? ( I saw a Canadian posted picture here once. We don't have them)
