Re: 37, 120 carb percolation problems

Dear rs:

That problem is caused by clogged main jet air bleeds. This causes a syphon action to occur which continues until the carburetor is empty.

The service procedure requires removal of the jets from the carburetor using a special extractor.

Thus, the unit needs to be sent to an experienced rebuilder.

Once this is done your car will run much better as well.
