I have a boat that someone put a Toyota engine into, and I am having carburetor problems. The engine was put away without fuel stabilizer; now it runs for 30 seconds or so gets rough and dies. The fuel pump, filters and fuel are good. so I want to rebuild the carburetor. It is an AISAN carb. with a tag # 37020, it is on a 20R engine. There is a stamped # in front of the 20R stamp 0424459.

Can anyone help me to identify the Carb or vehicle so I can get a carb, kit, or Weber model?

Thanks for any reply.

I am unable to find a 37020.

But I did find a 38020, which is a MID 76 Celica engine, california model.
All the Toyota carbs were basically the same, usually the only difference was CALIF or NOT CALIF and With or Without High altitude compensator. You could probably get any mid 76 celica (calif) kit and be safe that most of the pieces that you need are in there.

If the engine has a PCV valve, replace it. On my 1978 Toyota Celica GT with the 20R it acted the way you are describing when the PCV valve was clogged.
