Hello, New to the forum and have a question about a small issue with my johnson 15 (j15rssm). It was shutting off at low idle, and after rebuilding the carb and fuel pump, will sit at low idle just fine running on muffs. I thought all was well until I took it out yesterday and experienced it shutting off at low idle repeatedly (problem got worse as the day went on). When I returned home, I set it up on muffs again, it repeated the issues I had experienced on the water (a good thing as it helped to replicate the issue) and with an adjustment to the low idle needle, I was able to have it running fine again. I was not certain, and when I adjusted the needle, it seemed to have moved, perhaps under vibrations from running it.
For this carb, I did not see a way to add tension to the screw as one could do with the nut on the older johnsons. Is there a way to provide some added tension to this screw? I'm hesitant to use loctite, without confirming prior. One small item to mention, when I rebuilt the carb, there was an orange film/plastic on the low idle screw and tension spring. It appeared to be factory-installed. Does anybody know what this is and whether replacing it could be part of the fix?
thank you!
