I have done it in the past with great results, even on a 40 2stroke!!! I flare the copper lines a little where the hose attaches
and wrap wire around to help hold it on. As far as not enough oil, I had to put a resricter valve ( is that spelled right?) on
the Toro to slow it down a little, workes GREAT !! used a du-bro # 225 valve. On the 2 stroke people said it wouldn't work
because of even pressure but I did it anyway and it worked great. I put a nipple on the muffler where the one was for
the fuel pressure and the other REAL close to where the exaust enters the muffler,(most heat) and it worked fine. Everyone
at the field wanted to see the inside of the plane cause they never saw a forty size 2stroke smoke. I sold that plane and now wish I didn't.
