The 18TM has great compression and sticks at the top after 2 gallons of abuse. My 21 RG's on the other hand had hardly any pinch after a couple gallons. One of which I'm on gallon four and the other made it to 12 gallons before I had OSRocket pinch it. I've run 3 gallons or so on it since then and it still gets stuck at TDC.
But, like you said, if it's starting to be hard to tune and to keep it at idle, it's probably time for a squeeze. Although, I'd suggest using OSRocket or rayaracing. They have the right tools to do it correctly.
If you have OSRocket do it and it's a pullstart engine, make sure to ask for a mild pinch... Trust me!
