Greetings All,

I have read a number of posts about this issue, and have followed all the advice I could find, but still canít find my issue. Engine starts fine but dies in a few seconds. I bypassed the oil switch and can hear the fuel pump running, unhooked the fuel line to the carb and have a lot of fuel pumping into a bottle, I jumped the red to the purple on the ignition switch. I have 12 volts to the coil, Iíve checked every wiring connector I can find, but still have the same results. Starts, just wonít stay running. Also changed the water separator filter. Checked the lanyard. Have fuel going through the venturies. This is driving me insane! Any other advice would be greatly appreciated!
