Ignition problems on a '64 Johnson 9.5 HP

[tyofwa]

Last year we were running this motor when the transom clamp failed and the motor fell into about 10' of salt water. We retrived it, and fired it up in fresh water. I hosed it off as good as possible, and let it run for 15 minutes, starved it of gas, and set it in my garage until I could fix it. <br /><br />Yesterday, I replaced the broken bracket and tried to start it. Here is what I encountered:<br /><br />some of the carb linkage was stiff, the engine did not want to turn, and the accelerator ( timing advance plate ) was stuck. <br /><br />After thoroughly soaking it with WD-40, I freed up all the stuck parts. Confident it was all working, I tried to start. <br /><br />While there is gas getting to the cylinders, there appears to be no spark. I looked over the coils / condenser / contacts.. and there is a bit of surface rust, but other than that they are clean. I ensured a .020" gap, and tried again. No dice. I am tempted to track down a tune-up kit and coils for the machine, but I wanted to ask what troubleshooting tips would help me isolate the problem parts. <br /><br />Thanks in advance,<br />-Ty

tyofwa<br />Fairly obvious that the clean and dry out was less than complete. Since the engine was "stuck", there was water inside. I would fear there was bearing damage (rust) on the crank, rods, etc. When you do get it started it might not be for long. There are a lot of NLA new parts, no longer available, parts on this engine, but you can get all the ignition parts and a lot of used. Make sure the "stop button" is not shorting out the system. I would replace the points and condensers and see if that produces spark. If not, then replace the coils. At that point you have spark, then see if there is problems with the carb if it still doesn't run. You will probably put $50+ in it to see if you have a "runner" or parts for somebody else.<br />Backfire
