All I can say is..Don't try it.
Strain your paint, don't spray hot solvents with standard packings, Rinse it out well and insure that it is pumping clean thinner or water when you have finished using it and store it with either mineral spirits or "pump armor" overnight. For long periods of storage, pump in mineral spirits mixed with motor oil. Flush it out with clean spirits prior to using it again. If it's a gas machine, change the oil regularly.
You will lose all lubrication to the engine, and if you run the engine long enough you will have catostrophic engine failure.
your engine will not respond well when you try to give it more gas.
You get engine damage from lack of lubrication
the engine will lock up
Your car engine will stop.
Methylated spirits is a mixture of at least two things: ethanol and methanol. If you get it in Germany they put something especially evil smelling in it to make sure you don't want to drink it. But let's confine ourselves to the product sold in the US (where it's called "denatured alcohol") and assume it's just ethanol and methanol. Either alcohol combines with atmospheric oxygen to produce at least two new chemicals: carbon dioxide and water. If there's not enough oxygen in the area for it to burn properly, carbon monoxide will also be produced. You will also get a significant amount of heat - which is why you light this product in the first place.
no/poor gas flow to the engine. Results in stalling/stammerring motor.
it will make it spit and sputter and tear up ur engine
You will ruin the engine and have to spend several thousand for a new one.
The engine may not start and/or have poor performance. Drain gas tank and fill with proper fuel.
The engine will smoke a lot due to the oil in the gas and will run real rough.
