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
