Power Piston Travel?
« on: May 17, 2013, 07:13:31 AM »
How much "travel" is normal for this thing......#7040244, Buick GS 350....When installed, it only travels about 1/4"  to 5/16". Seems like hardly any movement at all. I don't know, maybe a little is "enough".  ???

There is no "normal" amount of travel, the factory used the APT system in the baseplate to fine tune metering rod height per application....Cliff
