I have started over 100 engines by pouring fuel down the carb and have never damaged a carb to date. Is it potentially dangerous? Yes, but so is trying to get into a Pantera without putting your back out.
Don't make something as simple as starting an engine that has been sitting a while into a $1000 three day adventure when it just not that hard.
don't you think it might have been a better idea to find the problem with the 100+ engines before
going to pyromania palace.
Geez you start half a dozen fires and suddenly you're a pyromaniac!
There was actually nothing wrong with the engines that needed the fuel, just empty fuel bowls. That's the point, there is nothing wrong. No need to buy a new carb just because you have a sticky needle and seat.
Gasolene, in order to be fuel, needs to be atomized. It needs to be mixed with air to at least a ratio of 20:1 to be combustible.
Water cannot be compressed. Liquid gasoline can not be either.
Keep pouring liquid into the combustion chamber and you will likely bend something eventually. Usually it is a connecting rod, but I suppose you could bend the valves too if you catch it right.
As far as pouring liquid gasoline down a carb to start an engine, I suppose opinions vary?
You can avoid a lot of the issue by installing an electric fuel pump to prime the system.
This will also give the inlet valves a chance to free up and the floats do their jobs.
It will also let you know if any of the carb gaskets are leaking because they dry up.
The Holley brand cork gaskets are really susceptible to shrinking as is the pump diaphragm. Best to prime the carb fist and let it sit with fuel in it for a while before you try to start it.
At first glance the Holley diaphragms sometimes seem to be holding fuel. When you go to pump the throttle though, many times they will rupture due to having been dried out.
Once you put fuel in the carb, you need to keep fuel in it or else.
The Ford carbs don't have really anything that can leak like that except for the inlet valves.
A simple rebuild on that carb should be all that you really need to do to it.
