In response to your youtube inquiry,
Is your timing wheel with the magnet as close as possible to the pick-up without rubbing it?
and
By chance, has the magnet fallen out of the aluminum wheel?

I use know Aspen 4 cycles (alkylate) fuel with god results.
In comparison with Coleman practically no smell.
I don't know if this type of fuel existe in US.

Also, the automotive fuel system additive Sea Foam is apparently a formulation of naphtha and pale oil. Would it have any advantages as top-end lube over WD40, 2-stroke oil, or Marvel in these little engines?

It's main ingredient is naphtha and I mix it 15:1 or 20:1 with Marvel Mystery Oil or any good 2 cycle oil or both. You can run them without oil but it is not recommended.
There are also 92 or 94 octane pure fuels (no ethanol) that is blended for yard tools which work fine.
Another source, if you have a nearby small airport is 100 octane Low Lead aviation gas. It will have a little less power but is very high quality fuel, lasts a long time, and has no ethanol.
Again, while these engines will run without oil in the fuel, I do not recommend it.
Automotive unleaded fuel now almost always contains ethanol.... also no good for your engine. It absorbs water and eats parts and oh yes, has a poor shelf life.
There are also a handful of poisons in auto fuel which are designed and blended to be pushed through a catalytic converter at 1400-1800 degrees. Our model hit and miss engines rarely get over 110 degrees.
I have bought. modified and resold a few of the M90 and M91 engines. I have added to the instructions Jin provides. (Jin is still learning)

I started my engine for the first time using 95 octanes petrol with a small amount of 2 stroke oil, it seems to run great so i,m not going to fork out for expensive fuel

On my horizontal engine no problem with Coleman fuel mixed with 50% (Swiss Neoval) oil.
Think he meant 5% thats 1:20 and that is more than enough.

i mentionned E98 and Pascal SP98, in France that means unleaded petrol with a grade of 98 octane ;)
Both of us add a drop of 2 stroke oil, even if Jin does not suggest it on its light paper manual.

Naptha burns with minimal ordors and resists varnishing.

I have a M91 and, as I was in a hurry, I started witj Zippo gas, VERY expensive, so I went and fetch E98 gas for cars and it operates absolutely correctly too. I am sure that E95 would be also usable.
I would ass that the carburetor needle adjustment is very delicate. For mine, it is a litle bit more than 90°
And I have a trick to help it for the first start, I inject a little drop of gas directly in the carburator ;)
