biggest issue right now is rust in the fuel tank. I drained the tank... then fished around inside of it with a magnet and got out what I could... still not good enough the tank outlet will plug with rust at some random moment.
I put a filter in the line between the firewall and the carb to catch the fine stuff before it got into the carb... but, being gravity feed, if the fuel is low, there is not much head pressure to push the fuel through the filter. I put it as low as I could and that helped.
But... I'll clean things up, get it running... head out on the road... and within a few minutes the outlet is plugged and I'm on the side of the road clearing the line.
Other than that...
