So im building a homemade flamethrower kit, but i have one concern in the tradition systems the engine coil gets cut off and raw fuel flows through the engine. I don't want that, since i'm going to be putting in a freshly rebuilt engine and i don't want my cylinder walls getting washed down. my question is will the exhaust still have enough raw fuel to produce somewhat of a flame? (i know carburetors aren't the most efficient and some fuel gets by) 3-6 inches is what im looking for, not the ridiculous 3'-20feet. The exhaust will go all the way to the rear valence, around the leaf springs(far away from the gas tank) DISCLAIMER: This feature will only be used at car shows(they designate a safe spot just for it) The components will be removed when the car is driven on the street(so i wont even get tempted) I will not explain how to make this kit, or how it works. So don't ask.
If you swap to a manual choke you can richen the mixture. I remember back in the day before they made kits...people used a T-Model Buzz coil to fire the spark plug in the exhaust tip. The coil got its 6 volt power from a switch mounted on the dash.
Thank you :Handshake My maverick is already set up for a manual choke. My system will be using full 12V coils and using a modern relay.
For a "flame thrower" to work you use the heat of the exhaust to vaporize the raw fuel and introduce it to the air and add ignition. There is no reliable way to run the fuel through the combustion process and then re-ignite it at the end of the exhaust pipe. You should be using a separate pump and atomizer to inject the fuel into your exhaust right before a fresh air venturi with a spark plug in the end of the venturi.
