Recently I was hard at work putting my "Dirty dog" into some semblance of presentable and encountered the common carburetor drool with the vacuum petcock. Yes, I know I need to dig in to the carburetors again to fix the float seat o-ring. But as a temporary and quick fix I thought I could cure the post gas tank oozing.
After draining the fuel tank and removing the petcock I removed the face plate of the petcock. I flipped the rubber valve body over. Then I found a flat piece of steel and proceeded to "lap" the face of the valve handle with 400 grit paper. After attaining a fairly flat surface I went to 800 grit and finally finished with 1500 grit.
When re-assembling I tweaked each bend of the round zig zag spring with a pair of needle nose pliers and gave everything a spray of silicone.
After re-assembly when in either the "Run" or "Res" setting I could not blow thru it.
Sealed!
