1994 Suzuki LTF250 - Carb Trouble

[tonyblue]

I bought a well used 94 LTF 250. When I started to repair and service it, 1 of the legs in the carb that hold the float had been JB welded. I could not find a body for a Mikuni BST 31 SS anywhere. I buddy had a mikuni round slide, I believe a VM series. It fit so I installed it with a small electric fuel pump. Did Suzuki switch to fuel pumps in 90 because of a lower tank design? It started instantly with no choke. To rich? Runs to rich everywhere but wide open. I lowered needle but still rich. Any ideas? Can the needle jet be changed? How can I identify what Mikuni I have? Should I give up and keep trying to find a BST carb?

Any help would be appreciated.

Thanks guys

You can also try contacting Sudco International. These guys are great with setting up carbs and specialize in Keihin and Mikuni carbs. They hooked my buddy up when he did the mods on his FCR 39 for his LTZ 400. Heres the link for the carb page. I never attached a link before so let me know if it doesnt work or you can just type Sudco International Good luck, I hate carb issues. They will drive you crazy.

I have fixed several of thease machines. The electric pump might be to much fuel. I use the briggs&stratton vaccum pumps, they just pump when the engine is cranking.
