Surging idle

[BRIELLY]

The floats were perfect. I took the fuel pump off and squeezed the bulb and got no gas out of the back. I even took it apart and checked but everything was good.

maybe you have a coil or spark plug dropping out. you can pull 1 spark plug wire at a time to see if the surging goes away. Is it only at idle that you have this problem?

[BRIELLY]

I didn't take the boat out but it seems to smooth out when I rev it up. When i used the spark checker I didn't notice the spark stopping on any of the cylinders. I'll try pulling off the wires to see what happens today.

[BRIELLY]

I changed the plugs and checked compression today. Its an even 105-110 on all cylinders. Its weird becuase it will idle perfect for a minute and then all of a sudden surge up in rpm's and blow out quite a bit of smoke.

have you had any luck? I've been towing non stop all weekend. Maybe I could take a look at it for you. It would only cost you a couple cold ones

[BRIELLY]

Cold ones are in the fridge waitin for ya. At this point I can't tell if its a problem with the linkage or possibly something ignition related. I had it running steady at 600 rmps but when I try to adjust the idle it barely responds. Then it will all of a sudden shoot up to 1500 rpms and stay there until I fool with the idle adjustment. I did have the throttle and shift cables off when I redid the transom so possibly something is out of adjustment. If you can help me out that would be great just pm me your contact info. I do have it scheduled to go to Fullers for repair on Saturday so I'm not sure if that gives you enough time to take a look.
