Are rebuilt 115 hp Yamaha carburetors available

[glueguru]

I have had an on going problem with carburetor issues - I winterize normally - drain the old fuel - change the water separator/fuel filter - the motor starts and idles normally but when a load is put onto it, it has stalls out

I have also observed insulation issues with the spark plug wire in the upper starboard side piston

Are there rebuilt carburetors available?

Am I chasing the wrong problem

why not test everything you can and then pull and clean your carbs

Sounds rich

try going 1/4 turn clockwise less than 1 1/2 turns 520 degree's and test

Have you tired rebuilding them yet?

Take your time read up online all you can worse case unscrew pilot and spray some cleaner in there. If you are handy getting the carbs off is not that big deal. Working and taking your time in garage with good lighting is only way to go. I am guessing 90 percent problems usually is fuel related.
