Low_Budget_Hooker Posted September 5, 2005 Share Posted September 5, 2005 Idle screw is located on the carb. Usually just above the bowl. It will be a small screw running through a tension spring. Quote Link to comment Share on other sites More sharing options...

Cujo Posted September 5, 2005 Share Posted September 5, 2005 one thing you have to remember is that its always going to be moving or in gear. it wont just sit still due to the disc always being engaged. Quote Link to comment Share on other sites More sharing options...
Low_Budget_Hooker Posted September 5, 2005 Share Posted September 5, 2005 LEFT- idle down RIGHT-idle up HOWEVER, this sounds more like a frozen throttle cable. Quote Link to comment Share on other sites More sharing options...
northgabassfisher Posted September 5, 2005 Author Share Posted September 5, 2005 we think its the choke on it. I might have to just brake down and have someone take a look at it. Quote Link to comment Share on other sites More sharing options...
NBR Posted September 6, 2005 Share Posted September 6, 2005 I hope you have some muffs or other water supply when running it in the drive. If not when you have someone look at it they had better replace the water pumo impellor. Quote Link to comment Share on other sites More sharing options...
Yankee_Bassman Posted September 7, 2005 Share Posted September 7, 2005 Are you talking about how to make it sit and idle in neutral while you start it, so it isn't starting in gear? If so, there should be a forward/neutral/reverse shift on the motor, probably on the side. I'd suggest you buy a Clymer or Seloc manual for it. Your local marine supply place should be willing to tell you the year from the serial number. Also, as NBR said, if you haven't been running on muffs or in a barrel full of water, you'll need a new water pump impeller; they fry in about ten seconds, and you'll blow the motor. If it hasn't been replaced lately, or you don't know, it's a good investment anyway, especially if the boat has been sitting unused. They dry out, and don't work. By the time you find out it's bad, your motor can be toast. It's not hard to do yourself with a manual, or it's not that expensive a job to have done.
