I'm appealing to the more experienced engine experts here. Do we really need a choke on these gassers?

I can see some value in using the choke to prime the engine.
However can't the engine be primed by plugging the carb intake (thumb method) and rocking the prop?

Does anyone run or start their engine with the choke on?

On some of the smaller conversions the choke shaft / plate / screw represent a significant disturbance to the air flow in the carb (when open). I would think the airflow would benefit with the removal of these flow disturbances.

Your feedback is greatly appreciated...

Sometimes I use the choke, sometimes I don't. Yes, you can just choke the engine with your finger. Flip it over until your finger gets a little wet with fuel, and fire it up!

Don't forget to plug the shaft holes in the carb when you remove the choke. If not, when you try to choke it with your finger it won't draw fuel.

Foamcut,
If the engine is cowled or you have a rear carb, the choke is required. Otherwise it is a covenience, which I prefer. If you remove the choke, don't forget to remove the ball bearing and spring used in many carbs for the detent. Plug the holes with JB Weld. If you don't remove the ball bearing, it will be sucked into the motor. A wipper style choke is a good alternative to a butterfly and makes life easier. If you reinstall the choke, use locktite on the screw to prevent ingestion.

Good catch Dave!! I forgot to warn him about that little steel ball and spring. Missing those could sure ruin your day....

av8tor / Dave,

Thanks for that excellent feedback.
I'm going to get rid of my choke and only install a wiper where I can't reach the carb throat.
