What would happen?
 

I'm just curious, and never have tried and never heard of anyone trying it.... but what would happen if i tried to run gasoline in a glow engine with stock carb ?

RE: What would happen?
 

I guess it wouldn't ignite from the heat from the glow plug and basically would never start?

Assuming you put oil into the mix of course

I guess he means after spark ignition conversion..

well, accurate metering of gas is possible but could be hard with stock carbs.

If the needles on the stock carb are very fine threaded, its possible to run gas with the stock carb.

As gas needs alot more oxygen to burn properly, the needle will be very sensitive and leaned out. (like the 0% nitro fuel compared with 30% nitro fuel)

A pump of some kind is near necessary to run gas as even the slightest change can lean out the mixture and stall the engine.

MJ,


If you use the glow-plug for ignition, the engine would start, but as soon as the glow-driver is disconnected it will die...

Gasoline is not subjected to the same powerful catalytic reaction of the platinum in the glow element, as is methanol, so when the power is removed, the coil would cool rapidly and leave the engine without an ignition source.


This catalytic reaction is the reason we all run our engines on methanol based fuels.


If you do convert your engine to spark-ignition (or to Diesel), you would need to replace the silicone components with ones that would endure petroleum fuels. The fuel-line is just one... Some carburettor and back-plate O-rings are also silicone.

Neoprene and Tygon components would be suitable replacements.

You'll want to read this link. These guys are cutting glow fuel with gasoline with good results.

Or if you are thinking glow to spark conversion and gasoline.

topic related question: let say Im running my 160FX with a mix of glow fuel and a little high octane gas. say its 30% gas and 70% glow fuel. or 40% gas and 60% glow fuel

which perry pump could i use for this mix? glow version VP30 or gas version VP30?

If there is any gasoline at all use the gasoline compatible pump. I put E85 (85% ethanol and 15%gasoline) into one of my silicone plumbed tanks and the fuel lines swelled up. The alcohol might shorten the life of the gasoline pump, but gasoline in the alcohol pump will destroy it immediately.
