Matt, the spraying of the fuel, or starting fluid, bypasses the workings of the carb, and puts the flammable mixture into the cylinders. You could drive a tractor back to the shop, when out of gas, by having someone walk alongside, and spray gas or starting fluid, (or propane), into the air intake, as you drive along. Engine will run fine, on an empty fuel tank.

My dad and I did this once with an F600 dump truck we bought. He sat under the hood and sprayed it while I drove it up on the trailer. I would advise against this, lol. Last time I saw that dump truck a crane had it in the air about 20' headed for the crusher, we doubled our money.

I recently saw a motor home burn to the ground because of carb backfireage, not cool. The guy who owned it is a retired fireman. He hit it with an extinguisher but it wasn't enough. Took the F.D. 7 minutes to get there.

This puts a lot of force on the engine components, I've known it to break the pistons....

My experience....I was not so lucky.

In my case I sustained second and third degree burns to my hand and arm from the spilled gasoline that ignited when the engine backfired. I learned that the best way to pour gasoline into an engine is from a very limited volume spill proof container. That way it minimizes the chance of a fire.

I don't pour gas, in. Either mist it with a windex type bottle, use carb cleaner or starting fluid, or an unlit propane torch.

I was only trying to point out that the fuel was bypassing the carb, when it is sprayed into the air intake, that it was not the same as choking, as Matt said. I've tested a number of non runners, this way, to be sure they don't smoke or knock, when the carb was full of varnish.

That could work. Unless towing with the tractor.
Hard to feed the strap into the carb from the operators station while moving though. :lol:

I need to weigh in on this but I don't know where to start

Flammable and combustible liquids themselves do not burn. It is the mixture of their vapors and air that burns. Gasoline, with a flashpoint of -40°C (-40°F), is a flammable liquid. Even at temperatures as low as -40°C (-40°F), it gives off enough vapor to form a burnable mixture in air.
REF.Canadian Centre for Occupational Health & Safety.

When you spray or pour gasoline into a carburetor you could to get the liquid on you or your clothing which can catch fire when the liquid starts to off gas and turn to a vapor.

I would never recommend pouring gasoline down a carburetor and stand over it while cranking the engine with the ignition switch on.I have done it in the past and I know the consequences for my actions.

My recommendation would be to use starting fluid, use short spray intervals and don't crank the engine while spraying the fluid.

Extended ( more than one use/ blast ) of starting fluid is not good and risks damage to engine.
Running too hot and too dry in my opinion. Carb cleaner can work a couple times but ....fixes nothing really.
If it won't run after being primed why fight it by giving it what does not cure the problem?

Yes I have been in a hurry to move something. That does not mean correct a problem though. Tarp it if weather is a concern and return to diagnose.
Feeding volatile mix without the air system installed properly begs a backfire. Never a healing process.
