Carburetor issue
 

While I was warming up the 223 in My '59 to check the generator I put on, when I would press on the gas,it would bog severely, almost to backfiring.

Saw this on the side of My Holley 1 bbl, I assume this is the power valve? Are ones for a 2bbl/4bbl carb the same?

is there any gas coming out of the top vent of carb?

I didn't notice anything

I ask because it looks like the fuel inlet fitting is wet...maybe from fuel, and that could cause many problems

I do not know if spark control valve is same or if that is your problemo, this site and Mikes videos on the you tube are GREAT info and help

Is the accelerator pump working? Hit throttle while looking into carb and see if gas is squirting from that little screw on the edge of the air inlet. Clear as mud right?

If not prolly the accelerator pump diaphragm inside carb.

There is a small fitting leak, that is the wet spot you saw in the pic

I'll check that out

Didn't see any gas squirt from that screw, so I pulled the accelerator pump diaphragm out, it wasn't stiff,or looked dried out. Maybe there is a passageway plugged, I guess I'll pull the carb and clean it

Accelerator pump was bad, found one at a carb shop in a nearby town, for $11 bucks. Putting it back together now

good deal, I also found that on my carb I did not need gaskets on fuel inlet line. I had a copper and fiber gasket and fiber was coming apart and getting needle stuck...

Did you file the back of the economizer valve housing flat before you put it back together? My carb leaked like a sieve until I figured out why. Carbs would leak all the gas from the bowls into the engine over night. I filed the mounting surface flat with a file and that solved the problem.

I'll check that before I put it back together

I put the new pump in, and the flat spot was still there. Yesterday for gits and shiggles, I took out the #60 jet, and replaced it with a #67. The flat spot went away, revs up smooth as silk with the choke wide open. I will still check the ignition timing (soon as I can find the marks)
