Thanks for the tips. I will definitely mix some SeaFoam in the gas this year. Normally I do that every year when I get started in the spring, but I will keep make sure I mix it in all year. I have also been told that some guys mix Stabid in their fuel all year, specially with the hot weather. I know of one place in Orem that sells "pure" gasoline. Maybe I should just go there each trip. From what I have read these older Yamaha carbs can be finicky since they has some very small ports. This is just the 3rd year of owning this motor and I have never had a problem until this year.
Got home today and the carb cleaner was delivered. Took the 3 carbs off the motor and started on them. Put the main body and jets of each carb in the cleaner to soak for about an hour.
Washed them in warm water and they all looked very clean. However, there is a very small port and orifice for the low idle. This is an orifice fed by the bottom of the bowl and it is super tiny and was clogged on all three carbs. Finally got them all cleaned out and everything spick and span and put back together.
At least I am getting a little education on this motor. I'll feel pretty good once I get it running right. Keeping my fingers crossed.
Will find out how it runs tomorrow. Waiting for the vacuum set to get here so I can sync the carbs properly.
Hope to get up to Willard this year to chase some wiper and walleye.
