Thanks guys...It's going to be a long and dificult reach to use my finger inside the cowl tho The 3W has a rear carb (Tillotson) and it looks like I'm gonna have to use a servo to actuate the choke. The guy I'm building it for doesn't want to see any choke wire sticking out anywhere, but getting the servo hooked up is gonna be a pain...Guess I'll just have to bite the bullet so to speak, and work out the details, maybe w/ a bell-crank or sumpthin'...
