JA: Sometimes things that you think will be really complicated end up being easy to fix. The Marine Mechanic I'm going to connect you with knows all the tricks and shortcuts. Is there anything else important you think the Marine Mechanic should know?

Has any work been done to the control box recently?

If you remove the cable from its attachment point, then use your hand to advance the linkage, does it function properly?

Other than you doing the carbs, has any other work been done to the engine?

I just bought it recently and the guy has done some work on it and everthing he did he left it undone like loose screws etc. so Im
gonna take it to a mechanic on tuesday so i guess you really cant help me right now but thanks anyway. I just thought maybe i could get some opinions to give the mechanic. I thought this would only cost me 5.00 instead of 25 so my bad.

A fewe things that you can look at before taking to the shop would be the cable hook up point. When you throttle up, make sure that it is moving properly. If it is not, the issue would be in the control box. If it does, the adjustment on the tower shaft is not correct.
