Throttle stuck
Well Igot my V20 running but it seems like when I try to set the idel the throttle linkae on the carb dosent want to come back down all the way when you have the throttle up and then bring it back down it wants to set and run at 1500 rpm. I was just wondering if there was a way to fix this. I thought about putting a spring on it like you would have on a lawnmower. Any ideas wuld help.

I'd look at the control cables to see if they might be either binding or need replacing.
Take the control connections loose from the motor, note which one goes where and take care to not revolve the adjusters on each. See if the cables are then free coming from the control box. If so, grease is needed at the motor portion or depending on the motor there may be a spring that has broken (usually not visible). If there is still some resistance, you have to go into the control box and determine if it needs greasing, is out of adjustment or if the cables are creating the problem. Final easy determination if the cable is the problem would be to have it completely removed from the control box and motor to see if it moves back and forth freely. If one control cable is bad, go ahead and replace both of them. It's just a matter of time for the other one to act up and a lot easier than doing it again. Post what engine you have in order to possibly narrow it down a little. Also there is no mention that it may have been adjusted previous. Sometimes they can be adjusted incorrectly and run fine then exhibit the same symptoms you have described.

Oh, one other culprit (depending on the engine) could be the ability to manually operate the choke butterflies to a position not conducive toward normal operation.
Basically, if the linkage to the butterflies are not in the automatic position but in manual or half way between the two it will exhibit the same problem.

Well I have a 3.7 Liter mercruiser in the boat. The choke is in the halfway position. It is electrcally choked. I had to fix this early today since the motor would bog down when I woul bring the throttle up.
