My friend owns an 87' Samurai with the stock carb, and he's been having some trouble with the choke. It will not idle in cold weather, unless you hold it at about 2000 r.p.m. for about 3-4 minutes. He seems to think it has to do with the fast idle cam, but he isn't sure, so he wanted me to post before he takes the carb off. Any advice is better than nothing...

choke

there are two parts of a choke on a samurai. the first is a heated coolant opperated, as hot engine coolant passes through the choke body a small rod extends and pushes on linkage to open choke valve.
the second is vacuum opperated. this open the choke valve a little bit when the engine first starts. it sounds like your problem is with the vacuum opperated part. the engine is being choked too much for the first 3 or 4 minutes until the water heated part starts opening, then the engine will start to clear. To check look at diaphram when engine starts. you will see it suck back into itself.

I have found on Samurais that the choke canceling mechanism doesn't work well especially in cold weather. Even if the choke "butterfly" does open some to allow it to run better when warm, it may not fully open to give you best gas mileage. On mine, I removed the butterfly to ensure it not restricting the airflow. To start cold you will have to pump the throttle before starting to provide enough gas to fire up, OK?

It is safe to remove the choke plate if you do not drop the two screws down inside the carburetor :eek:)
Poking a rag or paper towel down inside first for safety is good in case you drop a screw.
