Any tricks to getting the small side seal out without having the tool?

for the approach I use.

If you get the right Mighty Vac it will allow you to do both vac and pressure testing. I only have an old craftsman vac pump. It works well though.

Thanks Brad. Always enjoy your sharing.
You mention in your first video you first tried to cure the problem by tinkering with the carb to no avail.
I recently posted questions to Mattyo and I have copy/pasted here. This is not a test. LOL. Varied opinions are valuable.

Before we press/vac test we must have a reason to be suspicious. In your opinion will a saw H tune to 2-stroke at the desired rpm if there is a small air leak, large leak, any leak? If the H screw tunes fine but the idle speed varies a little (not racing) and cannot be cured with tuning the L screw, is a small leak suspect?
Can mods like porting, squish cutting, muffler opening, and timing advance cause little irregularities that mimic an air leak? In other words, at what point is a saw grounded awaiting an air test?

Why not clean things out better first?
