Re: thumb throttle will it work?
There are a lot of builders who prefer the thumb style like those used on ATVs. What you don't want is one that doesn't return to the idle position when released. There are a few who like the idea of 'cruise control' using a throttle that stays where you put it. In my opinion that is an accident waiting to happen.
The throttle should automatically go back to idle when you release the pressure. It is an important safety feature that you need to consider.
