Hi, New guy here. I recently purchased an 87 Gehl 3510 with a Ford 4 cyl. VSG 411 engine. The problem I have is the carb. It has a variable venturi carb that floods the engine with gas. I have found out that parts are not available for the carb and nobody wants to work on that style carb. I'm thinking I'm not the first guy that needed to find a replacement for it. I have the original manuals that show a second carb...a single barrel downdraft model. It doesn't give much info in the manual. Has anyone found a replacement carb or does anyone have an original downdraft style carb that they would be willing to sell? Thanks, Chuck
