Problem Starting Older IDC Blower / Vac

I have an IDC blower vac that is around 10 years old. It worked fine this summer. Then when I tried it yesterday, although I got it started, it died on acceleration. With much tinkering with the idle mixture screw, I was able to get it to run on full throttle without dying. After about 10 minutes of pretty good running (with some choppiness at times, when I had to release the throttle and bring it back up to full throttle slowly to prevent it from dying), the blower stopped, and I have not been able to get it started since. I tried brand new gas (with 2-cycle oil mixed in), I have disassembled some of the main parts -- the fuel is cycling through the fuel lines and the brand new primer bulb just fine. I also replaced the spark plus and air filter last week, so that can't be the problem. I even checked the spark plug -- with the plug removed and grounded to the engine, I can see that it sparks when I pull the starter cord every time the piston compresses -- several times each pull.

Does it sound like a carb disassembly and cleanout is what is called for? If so, can I re-use all of the existing carb parts after cleaning, or do I need to order new carb parts? Thanks!

Try squirting a little gas into the cylinder and see if it will run for a second or two. if so, you have a feul related problem. If not, you likely have lost compression. Those IDC products were not famous for long life.

Removing the muffler will give you a good view of the cylinder and piston. Any scoring and it's toast due to the fact that you will lose vacuum to draw in the fuel mixture.

Depends on what is wrong, and if they are still having problems since this thread is 5 years old.
