Carb Varnish

[Deleted]

Short of an expensive trip to a professional mechanic, does anyone know of a way to unclog my carbs as a result of old fuel? Thanks in Advance (2001 Yamaha 100 four stroke).

Well I have a Yammy 115 2 stroke and when I got my boat she had sat for close to two years. I did everything I knew how to do and talked with folks on here and ended up going to a wrench to fix it. I'm sure one of the guys here with a 4 stroke could help you out.

You can try draining the fuel bowls and lines down real good, reconnecting with a fresh fuel and sea foam mix and see if it will break up that way. Marvel mystery oil works good too. If it's not too bad it may clean them up but I am guessing it's pretty bad (i.e. motor won't run at all right now). If that's the case, you are most likely looking at rebuilds. Good luck.

Thanks, I did dis-assemble the carbs, soaked each one for 12 hours and re-assembled them. Their was green jell in each of the float bowls. Now it tries to start but won't run, I trouble shot the kill switch and ordered one. Hope that fixes my start problem.
