One cly. blues..

[DLJ]

I have a 35 horse johnson that is running on one cylindar. I know that the coil for that cyl is good cause i put a new coil on and is still only running on one cyl.The plugs are also good. Any other suggeations on what I could check? Thanks in advance. DJ

Howdy, DLJ. You know the plugs are good. Does that mean you have pulled the plug and watched it fire? When you pulled it, was it wet? If not you have a carb problem or a reed problem. If it was you need to check the compression. A quickie compression check is to stick your finger in the plug hole and turn her over. It should blow your finger out. No/low compression could be stuck or broken rings. Check out the above and get back to us.<br /><br />Good luck.<br />JB

Hi there and thanks for the reply. I went through the carb and it is as clean as can be-this is what I thought the problem was at first. Found out it is an electrical problem and the bottom cyl is not getting spark. I know both plugs and plug wires are good cuz I swapped them with the top cyl and it still ran the same. I relpaced the coil and that didnt solve it. I figure it must be the power pack, but how do I test it to see if it is good or not-instead of buing a new one for $80 and hope it solves the problem? Any suggestions? DJ<br /><br />PS-I have good compression in both cyl.
