Re: 9.9 Johnson Carb Question

quote OptsyEagle:

I can’t say it will fix your problem but if I was having a slow idle problem I would definitely remove the welch plug and the slow speed needle bearing and clean them cavities out well and replace them with new ones. It is not difficult to do and the parts are maybe worth $10 in total. Keep in mind that the slow speed needle bearing is made of plastic and plastic parts are not fond of carb cleaner. A little is fine but maybe someone soaked that thing in carb cleaner over a few days. Not sure a plastic bearing would hold up well with that. In any case, just replace it. Might as well replace the retainer needle valve as well. It is also made of plastic and is critical to maintaining a good seal. If air sucks past that it will never idle well.

Thanks for the info about that bearing. Up until I came across this thing, I never hears of one being there. I will try another know good carb (borrowed form a good running motor) and if the good carb works, I will take the welch out of the bad carb. I have a lot of various size welch plugs left over from many carb kits where I didn’t need to pop them out, so I’ll find something that works. Is the bearing and retainer in OMC or Sierra kits? or do I order that separate?
