Hi w8ye, that was a timely post!
Is your "regular pump gas" straight 92 unleaded? Here in Ozzie Land we have E10, 92, 95 and 98 Premium.
The 92, by law, can have up to 5% ethanol. The Pennzoil 2 stroke oil is available here too.
Is "the Saito carb" the standard Saito 150 glow fuel carby?

Yes it is the regular Saito 150 glow carby
Our regular pump gasoline is listed as being 89 octane but it is the same as your 92. It is E10. The octane ratings are measured different
I have about 10 hours on it.

In reply to RossG (Radial) ,
E85 is closer in fuel mixture to methanol than straight gas and should give a steadier needle setting and better power in a Saito engine than straight gas. I think my plug was fouling because of the castor oil I used, I'm going to try some synthetic. Sadly, I don't spend much time tinkering with my RC stuff since I got an RV-4. -Tom in CO

RE: Saito 91 on Gasoline
I am building a twin with 2 ST G90 on it. I would like to put ignition and a CM6 plug on them and still run glow fuel. Will this work? The reason I want to do this is I want to mount tacks in the wing behind the engines.

You will need to search for the needle bearing the others are using and select the proper size drill rod for the crank pin to run less oil.

RE: Saito 91 on Gasoline
how bad does the spark plug may affect the engine tunning?
I´m using cheap chinese 1/4-32 on my ST90 and it is great on high speeds, but a little unstable on lower speeds.

On some engines they may slip a couple times before they settle down and you will have to re-adjust the timing but I never had this problem.
If seen the prop drive washers that were split and these will never hold a permanent setting. If you have trouble, examine the hub carefully.
