off idle stumble

Excellent idea. Screwing a screw into them to pry them out doesn't mess the tube up too bad I guess?

Well I took apart my practice carb and pulled the idle tubes. One of the tubes came out without much difficulty but the other one was a bit of a problem. When I tried driving the tube down inside the collar, the collar was moving with the tube. I had to tap it a little harder and the top of the tube deformed a little. Then it didn't want to pry out so I had to heat it up. After a few tries it finally came out but the collar doesn't look too good now and I'm not sure about the tube. Any way these tubes look real clean and I can blow through them so I guess they aren't clogged. After messing with this carb I'm not too sure about doing the same thing to my keeper carb. Maybe I'll do like Cliff says as an alternate in his book and stick a wire in the tube to make sure it's not clogged instead of pulling the tubes out. I guess I'm still not sure why I should need to drill these out for the factory #'s carb on a stock engine? I really appreciate you guys taking the time to try to help though. I hope that the tubes on my keeper carb are clogged and poking a wire in it will fix my problem.

Well I thought I would update this post after I found out why the engine was floundering at high rpm's. It turns out I had a broken valve spring and luckily didn't drop a valve. The engine runs much better now and revs up without a problem but I still have the stumble off idle under load or no load. Is my only option then to drill out the idle tubes and such? Maybe I should just send the carb to Cliff. I really don't want to mess this carb up.

I have only a couple of ideas. look into the carb to physically see if the squirters are working AS SOON as you touch  the accell .(ignition off) it is possible that the pump could be set too high. if the cup is above the fill slot you will have a dead spot. it doesn't happen too often but is possible. its an easy fix though with the carb on the engine. also, make sure the vac advance hose is in the correct vac source port. I would set the idle with a vacuum gauge. you could try a little bit more timing also just to see what effect it has. if the idle speed goes up right away fast with a little more advance, put 2 or 3 more degrees of advance in it. readjust the idle to a lower speed with the curb idle adjustment screw. this will help the transition to the off idle. Also look for vacuum leaks.
   I hope the rest of those valvesprings are ok. Out of ideas other than those,
