Reply to "Holley 650 Question"

It is most likely the float levels are to high.

This is an immediate danger of fire hazard and you should stop right there and correct it before it catches fire.

Having said that, it could be flooding for a couple of other reasons. 1)needle and seat need to be replaced, 2)brass float colapsed or partially collapsed 3) too much fuel pressure.

With an aftermarket Holley you need to change the automatic choke thermostat to a 351c specific one. If you have an aftermarket automatic choke, you have the wrong choke thermostat.

The Clevelands are particularly susceptable to this.
You need a choke thermostat from a factory setup for a Cleveland.

They can be hard to find. I find a 68-70 428 Mustand CJ carb choke as an acceptable substitution.

They open and close at different rates then the universal aftermarket chokes supplied with universal applications.

This is particularly noticiable on warmed up or partially warmed engines. It makes them hard to start and prone to stalling until hot. Then it makes the hot engine hard to start.

Get the right choke thermostat but check the fuel levels first unless you want to do a tailgate party and use your Pantera as a Hibachi.
