I have an old 120S-E Surpass that I just took out of the box and am breaking in. While running on the test stand, a small stream of fuel kept blowing out of the crankcase vent. I have a couple of .91 Surpasses and a .70 Surpass and none of these have any visible fuel discharge from the vent. Is this normal for the 1.20?

Thanks,

Jim

Larger engines burn more fuel. That means more oil will be blown from the crankcase vent. Also, newer engines won't have as good a seal between the ring and liner, so you'll have more 'blowby' until it breaks in a bit.

That sounds logical to me. Thanks for the quick response!

Thanks again, Jim
