Next, have the exhaust gas checked using a gas analyzer and determine the current mixture reading.

The cold control and system pressures are OK but warm control fuel pressure is too LOW!!!! Check the WUR cold control fuel pressure from start to 3 minutes. There is another post today, where I suggested this simple test. Could you check the WUR ID number?

I could lend you one of my spare WUR's for your test in case you need one. Do you have the -072 or -089? Keep us posted.

That pictures is awesome! you want a used 008 for that collection?

Area man stick with Tony on K-jet pressures.

Cheers,
Matt
