I have a 90 V200 S#0c219197. I checked the timing, carb and thottle linkage, new plugs, comp test 115+ all 6, new primer bulb and fuel hose, new fuel filter. It has ran fine till about 2 trips ago. I ran out the old gas last week then filled up. It started right as the tanks were empty. When you go to launch it just falls flat or if it don't die it won't plain off. I filled up changed the filter cartrige, and the plugs. I did notice that if I hit the enricher when it is nose up it will take off. Does this sound like a fuel pump or carb issue to you? Thanks.

You need to disassemble your carbs and clean em'. Reassemble with some new gaskets.<br /><br />A fuel pump diaphragm kit is cheap as well and you could rebuild it while your at it. It's a good idea if don't know the last time it was rebuild. However, you problem lies with the carbs.

Have a freind pump the bulb as you try and get on plane, if that works, its the pump.
