This makes no sense to me.
Whats the point of a gas engine in .90 size? Can't be fuel economy. A 90 doesn't use that much fuel anyway.
Another thing:
I asked a question about putting needels on the rods. The consensus was that it would wear out the crank pin if you put needles in the rods. Wasn't worth the extra $3 to put bearings on the rods.

People had done it before and it just wasn't worth the hassle.
Now we see this little bitty .90 engine and people are speculating that it's got needles on the rod.
If it DOESN'T have needles on the rods--then it's pointless. The methanol in glow fuel isn't the expensive ingredient. Nitro ain't too bad either. It's all the darned OIL that makes glow fuel so expensive.
So--if there are NOT needles on the rod--then you'll be running 10% oil or more. There goes the price of your fuel again. Might as well be running it on glow and save the weight and cost of the ignition.
I am real interested to know if it has needles. Also interested to know--Whats the point of it? A .90 size gasser?
