Got my $70 ebay petcock, it's in great shape. I had no reason to think it would leak all over the place when I installed it
I got most of the old liner out of the tank after a good bath in 'The Works' The molasses did nothing...I rinsed it out and gave it a good baking soda wash to neutralize the reaction, rinsed it out some more, and filled her up with gas after drying out in the hot sun (We broke some records here in the Bay Area today).
First I thought the petcock wasn't screwed on tight enough, so after spilling gas everywhere to tighten the screws, the lever wouldn't move anymore, and it
still leaked. Luckily, I had cleaned up the PO's jerry rigged petcock with some carb cleaner and a new filter, so for now I'll use that.
So, all this cleaning, gas spilling and frustration took up about seven hours of my day off. To top it off: When I went to start her up...the battery I'd charged up was dead
On the bright side, the PO found the pipes he said he would give me.
Oh well, tomorrow is another day.
