How much blower oil?

[Ross Buettner]

My 4M was low, almost out.

I drained what little there was in there and cleaned the window plug out.

How much goes in? I think I have like a cup in it and it seems overfull?

fill it until it is centered in the window. i use 19 oz in the rear and 21 oz. I think in the front.

my manuals say...
for a four inch gear blowers use...
vertical...3/4 pt
horizontal...1 pt

i jus fill till it comes out the "level hole"
