Thermoquads are great if you are willing to pull them off and re-kit them about every other year, and adjust them every "season" for proper operation.
I pulled the the one off my last carbed daily 3 years before the truck got wrecked. I was tired of constantly jacking with it. The last 3 years of its life, I ran a Carter AVS. It ran untouched those last 3 years, and would have continued to function correctly for at least a few more.

The truck ran a lot harder with the Thermoquad (when it was in tune) then it did with the AVS, but the AVS didn't need constant attention. I've been carb free since 2011 (except the mower) and I intend to stay that way. Gene
