Re: Outboard Carb Float Stuck?
Yep the model says it was build as a short shaft, manual start 10 hp. I figure you know it was common to change them to 15hp for state parks with ahorse power limit (10 hp). that same model number is a give-away to LEOs.
If you are using it on 20 hp lakes or greater then the 15 hp carb is a keeper. If you are on the lake that has not been changed, it is your call.
The needle/float valve is stainless with a plastic tip. The valve and the valve seat are readily available for about $10. Any dealer can get, try to take the part number for your 15 hp carb with you, but I believe the 10 and 15 hp use the same float valve assembly (different jets for sure).
The complete carb rebuild kits for your 85 are also readily available and cost $30-50 depending upon where you buy it.
I'd first try to fee the sticking float valve (tap or Gum-oout) unless you are comfortable taking the carb appart. If you take the carb appart and get the kit, you will get new gaskets; you could have a gasket failure, so new gaskets are good insurance.
Hope this helps, those are good 2 cylinder engines, and should last forever with proper oil and maintaince.
