Air leak
Fuel pump
Float level


I'd start with that list.

Are you using 5/16 or larger fuel lines?

I have check for air leaks, dont seem to have any. As far as the fuel pump a local mech. told me to have someone pump the bulb went it started to do this and if it started to run than it was more than likley that. I have done that and it does not help. Do you think that maybe it might be a powerpack.

You might want to go through the fuel system, including cleaning the high speed orifices and the anti-siphon valve really well, before you start looking for an ignition problem at that level.​

I also have another question. On top of the fuel pump there is a red knob with what looks to be an air valve stem. What is this.

The red knob is on the primer solenoid which takes the place of a choke when you push your ignition key in. When the battery dies, you can manually prime the engine by turning the knob to a right angle from the cylindrical solenoid and squeezing the bulb on your fuel line.​

Right now the knob is turn pointing strait down. In what position should it be setting.

On the WOT issue. I took the plugs out to have a look. The two on the port side look fine, the other two are pretty black.
