175 Petcock Turn Lever
« on: October 14, 2019, 09:39:54 AM »
Checking to see if anybody currently has a 175 petcock taken apart and could post a picture of the backside of the turn lever.

I have one that doesn't look quite right and would like to verify the flow cutout on the back side.

     Can't help with a photo.   Could this be anything to do with different taps?on the DT and HS models as found on the GTR/GTO machines. IE, Tap action is reversed on the GTO to clear the high pipe.
Unspoiled by progress.
I'm so glad I grew up in the 60s & 70s. I did so much stupid stuff and there's no record of it.............Anywhere !!

I don't think so, it looks like it didn't get cut out properly. Hard to describe, Ill take it apart and post a pic soon.

Ok, here's a pic of the 175 lever (right) vs a 350 lever (left)

What confused me was that I'm use to working on the 350 stuff and I remembered that they had a "continuous" cutout to direct flow from the tank to either the regular or reserve source.

Then when cleaning this 175 tap I saw it had just 2 holes drilled into the back of the lever and didn't notice until now that they intersect at the bottom which allows for fuel to flow between both holes.

Question answered!  banana
