Re: Electric primer solenoid "valve"?
It's a place to injcet foggging oil and decarbonizer. You can just spray the same products straight into the carburetor throats. If you want to upgrade, there are kits available with just that valve/lever. Easy to install, just loosen the cap and swap them out. Then put the cap back on.
What that valve allows is aerosol products to be injected via the primer hoses. thing I don't particularly like is that it leaves a lot of the product in the hoses when it comes time to start and you want gas in them.
