2150 high alt carb

[clavin001]

What is the front middle port at the base of the carb for?

The line that goes to the bottom front center of the bowl? That vacuum line supplies a vacuum signal to the power valve. Any fuel in that line and your power valve is blown and needs to be replaced.

What are the symptoms of having a blown power valve? Are the power valves for the 2100 carb the same as the 2150?

[reddog]

It will run rich. Exhaust will smell of fuel. Runs rough or not at all at idle. Do you have fuel in that vacuum line?

I am not sure if the power valve for the 2100 are the same as the 2150. The correct valve is easily available.

You might look at this thread - POWER VALVE (http://www.ifsja.org/ubb/ultimatebb.php?ubb=get_topic;f=2;t=005047#000007)- or do a search on power valve.

Yeah, there is some fuel there(it's not running out or anything). Just a little wet and fuel odor. Could a bad power valve effect cold weather starting?
