15-50 syn motor oil per Husk service supervisor; I think they had to call Stockholm. That was bigger secret than the kentucky fried chicken receipe ~
Thanks for the quick reply Eugene. I can only get the part number as well from the manual; I would have to tear down the blower a bit to try and find a plate on the transmission. I will see if the local shop will give me grade later this week - was just trying to take care of while I had it out / on my mind ~
