Choke/enrichment part stuck in Mikuni Carb - Snowmobile Forum: Your #1 Snowmobile Forum

79 El Tigre 5000 with 34 MM Mikuni carbs.

I pulled the carbs off to clean them up.

Clutch side carb came off without any issues, but have a problem with the Starter side carb.

I was not able to remove the "enrichment plunger", it seems to be stuck in the bore.

I left the "choke cable" attached and removed it from the sled. Except for this issue the carbs seem to be in great shape. Not worn and no crud or corrosion in either carb.

I sprayed PB Blaster in the bore and am going to let it set overnight.

Any suggestions on how to get it out without ruining the carb?

Thanks, Joel

Needle nose pliers.

Pulling really hard with Needle Nose Pliers will probably either get it out or break the cable off, but is there some reason it will not damage the carb in the process.

You can get the cable off with it still in the carb.
Take a small self tapping screw and run it into the top of the slug and then you can get a better grip on it.

I was able to get it out.

Used carb cleaner and PB Blaster for a couple days. I then cut away the spring that holds the plunger down. This let me put a screwdriver down into the slot in the top of the plunger. With the screwdriver I was able to get it to rotate slightly and just kept working it back and forth and pulling. Eventually it came out and nothing appears to be damaged except for the spring I cut off.

Persistence pays off once again!
