I am really getting a good taste of the complexity of keeping a boat running. I opted to rebuild my carbs over the winter because the engine was starting hard and idling rough. And that is just where it started....

After rebuilding and cleaning the carbs three times, the engine still won't idle. I have an air leak or fuel flow issue somewhere I have yet to find. And now as part of checking every possible component that could cause me issues, I have sheared off the pulse limiter fitting in the block. If I can't get it out with a screw extractor, I am going to have to pull the entire intake manifold and drill it out!! :mad:

And here it is spring time and all I want to do is get back out on the water!!! This is the project that never ends!!

And to think that I had no issues last year and thought to myself that all those bad boat sayings didn't apply to me!! I guess the boat gods straightened me out, huh :)

Thanks for letting me rant!!

Call me "Cursing in Carolina"....

Re: The never ending carb rebuild

Bad results while performing boat maintenance is almost always due to improper procedures or lack of knowledge regarding the process. Which brings us to once again to remind everyone that unless you've done the job a couple dozen times before you cannot underestimate the value of a factory service manual. Very few people can open up an engine and be reasonably confident they can succeed at performing every diagnostic, fault isolation, and repair operation properly. Trial and error can be very expensive when it comes to outboard repair.

Re: The never ending carb rebuild

True statement. I actually do have the OEM manual and follow it explicitly. It is the "having done it a couple dozen times" part I am missing!!

Believe it or not, I actually design, build, and repair electromechanical machines for a living. I can troubleshoot an environmental chamber or vibration table in my sleep - an outboard, not so much.

But you are right, experience can be an expensive teacher :)
