btw: I'm willing to bet you can get a Bayco to work just fine on your unit, I have one working right now on an
AT unit, Mike was just concerned as his was pulling high with the 18"hg valve on it.
If you want to give an 15" or 18" valve a try Jim, it pretty much just screws on, it's your to try for the cost of postage.
If you aren't dual wanding, save your money and lube your existing spring.
