Has anyone removed the pressed in idle feed plug in the carb body that captures the idle check valve. The idle check valve has a defect preventing the purge bulb from drawing gas from the tank when inflating. Zama says this is not repairable but I don't believe them.

When the manufacturer says it is not repairable they are probably basing that on the cost to repair it, you would probably have to drill out the old one, then find a replacement check valve and then find a way to hold it in place. I think you can now buy those carbs new for $15-20. Have a good one. Geo

I've removed one or two just to see, but didn't fix them. Buy another, they are cheap.

cheese,
How did you remove the plug. I would like to remove it so it can be reinerted or replaced with one turned on a lathe after replacing the check valve.

I pushed it out by prying on the protruding part on the inside of the carb throat.

cheese,
I think you are referring to the high speed jet. The low speed jet is a series of holes in the carb throat on the engine side of the carb near the choke butterfly. The low speed jet (holes) are fed via a pressed in plug (not the welch plug) on the metering side of the carb body. It is located in line with the low speed adjust screw.The pressed in plug also captures the idle jet check valve which I believe is defective and preventing the purge bulb from drawing gas from the tank when inflating.

I had in mind the main fuel nozzle and check valve. The idle check valve is under that long thin welch plug with a round end.
