Favorite carb fuel additive?

I use ethanol free and red Stabil + MMO for my OPE as it takes quite a while to deplete my fuel can.

All my 2 stroke engines require 40:1 mix and following Marvel's instructions, I replaced some of the 2 stroke oil with MMO. After a few tanks, they are actually running smoother and idling better. That's the only noticeable improvement I ever witnessed from MMO. Must have been quite gunked in there.

Ducked. If paint thinners are sold in Taiwan, you should have acetone,toluene and xylene . Toluene is an octane booster,the other2 are solvents

My dirt bikes and mower aren't used much during winter months so I usually add fuel stabilizer (Sta-bil, seafoam or the like) prior to the onset of cold weather. And I run them about once a month during these off-periods, it's just not good for any engine to sit for extended periods. Never had a fuel-related issue. Also I should mention that I run inline fuel filters which are not standard for dirt bikes.
