Subject: Honda express automatic Choke

I am restoring a 1981 Honda Express SR that has been sitting in an Ohio barn for several years. It has 610 miles on it. It is generally in mint condition. I've soaked the carb and flushed all fluids, etc. I had the exhaust muffler soaked in a hot grease removal tank. Got a new battery. All set to go.

I need only one question answered: How does the automatic work? It seems clean and workable...what ever that means.

I have looked all over the web and can not find any info on how it works. It is on a Kiehim carb, and nowhere does Kiehim talk about it.

HELP. Mike in Ohio.

Hi Mike,

Autochoke should work with a bimetal strip that ups when cold and shorts when warm.. When you start up cold the rpm goes up to get warm, at a certain temp the metal strip shorts the system and it goes down again, nothing to it..

Anyone else got info on this?
