Gas odors

Mr. Jody - that sounds like a good hint. I will take a close look at it. When checking around for any sign of dampness on my fuel lines I did seem to detect a bit or oil or something on the bottom of my pump, so it bears a closer look.

Thanks

Yeah - these cheap Holleys (no external float adjustment) are really a headache. I need to get some decent ones. The last time I drove it I took the air cleaner off when I shut it off and listened and looked for any sign of perculation but couldn't detect any. Keith Craft was supposed to install a valley shield under the intake and I believe he did - which would help a little with the temperature at the intake, but maybe not enough.

Thanks
