Here is the deal. I have a 1984 suzuki dt115 that sat for two years. I have changed the impeller, rebuilt the carbs, changed the plugs, changed fuel and oil hoses, and rebuilt the fuel pump. The problem is that the engine seems to be running fine but when I go to take off it has no power. When it gets going finally the rpms are only running a 3400 full speed. I have checked the throttle linkage and everything seems fine there. I have checked the prop and that is correct. Is there something I am missing? Any suggestions? Any help would be appreciated. Thanks Brad.
