Very surprising. Especially to rev up and also idle.

Walbro sells a special carb for 25-30cc model airplane engines the WT-499 that can be adjusted to run Alcohol as well as gasoline.

It was made up years ago for the Zenoah G23 alcohol model airplane engine but just happens to work fine on gasoline if the needles are closed down some.

Those Zenoah alcohol engines didn't work out so well as the bearings would turn to rust on the inside.

But the WT-499 is still around. It has a 27/64" (11.11mm) venturi

More of I blipped the throttle it reved a little and came down and kept running.

And it was fighting itself from flooding out.

I just was checking that it would start, run and didn't have any serious issues, since it was
a pile of parts that I had put together.

Some people try to run their alky saws a little on gasoline to try to get the alky out of them before putting on the shelf.

Adam my 5000 with external boost ports had a MVP 272 100 alky carb.  I was able to run saw on gas just off the seats from what I remember on settings. Saw ran great on gas as that was what it was built for. Then later switched to Nitrodine and carb was able to flow 12% to 15%.  Never could try the 30% like the 262 liked.

That's interesting. I've tried that on a few of my alky saws to no avail.  Compromise at best IMO...
