I have, a ST 51 with muffler pressure on gas only and spark it seemed to run as well as the Walbro.
This is because the carb. is set up for glow fuel. The carb. can meter more fuel than a gas carb of the same size.
There are internal adjustments that can be made to the Walbro carb that will help it meter more fuel.

You have a ST-51 on EI?

The alcohol is what keeps the glow fuel lit.
With spark I would think that a 50/50 mix should work and would be easier to adjust the carb. with than a 33/66 mix.

So what is the engine doing or not doing?
