The thing is..........when you are cruisin' down the road and give it throttle..........the pump could be unhooked and it should still run OK

i guess taking the front bowl off and the front metering plate is a good move on all accounts. can check for sludge and check the power valve. will the power valve be noticeably blown just looking at it? how do i check it? or is it just a good idea to change it if its apart?
