Got a 1987 model 90 from a friend. It has been sitting up for 5+ years. I have done the following:
Replaced t-stat,poppet valve and spring, rebuilt carbs, drained and cleaned oil tank, new fuel lines, tested alarm (good), tested overheat sensor (goes off at 160 degrees), bled oil pump at bleed screw, replaced plugs, and impellor.
Having run it on ears in the yard I checked the head with a laser type thermometer highest temp at 1000 rpms is around 160 at the top of the head. Is there anything else I should replace or check on this motor before I take it to the lake? Does anyone know an avg. operating temp for these motors?
