Is there any chance that you have fuel in the tank left over from winter?

Winter gas is formulated to boil at a much lower temperature.

Hence in hot weather this fuel boils very easily.

This is the reason that I put a tag on each gas can that tells me whether it is S or W gas.

If I find myself with the "wrong" gas then I just put it in one of the Fuel injected cars and burn it up.

Using the SUMMER gas around here in the SNOW BLOWER causes a "no start" condition or it only runs with the engine choked for an extended period of time if it is cold out.

In other words engine dies if not choked.

I doubt that Stabil or Marvel Mystery Oil helps in this condition.
