The M/S carburetor is stone stupid simple, do it yourself. getting everything absolutely clean is the main thing

If it was fun to pull in LOW gear, I could have a John Deere.
Real pullers don't have speed limits.
If you can't make it GO... make it SHINY

A few years ago, Dick L, a forum member recommended putting a carburetor in an old pan with some non-sudsing soap and bringing it to a boil (I use an old two burner hot plate we used during our kitchen remodel a few years ago) and letting it boil for about 5 minutes.

Before I start, I get together a set of screwdrivers that fit all the fittings you plan to change, a good pair of pliers (to pick the carburetor out of the hot water) and a pair of leather gloves to keep from getting burned. I lay out a leftover piece of vinyl flooring (cut out from the bathroom where the shower is), which is real easy to clean up and I have a bunch of paper towels nearby.

I take the carburetor bowl off the top and remove the float and set it aside. I remove the jets and anything else that comes out easily and is easy to clean. The top and bowl of the carburetor go in the pan to boil for 5 minutes.

As soon as I shut the heat off, I pick one piece (usually the top) and start removing pieces. I usually clamp it in the vise. After I get everything removed, I use torch tip cleaners, (aerosol) carb cleaner and my air hose to completely clean all the passages and make sure everything is very clean before reassembling. If they are really rusty, I sometimes hit it real lightly with the sandblaster.

Reinstall everything and set the jets both at 1 1/2 turns to get it running and adjust after it is running.
