1976 Scamp fuel gauge problems

Well, I went on eBay and I found several clusters and I was actually able to win one at $36 + $20 shipping. The speedometer is not completely correct and neither is the wiper switch, but it has what I need to get everything on mine working again; I hope. Also did a valve adjustment and it's a ton quieter. I drove it to heat it up and then did the valve adjustment hot and running with the idle all the way down. The tightest I found before I started was .060", loosest around .080" and they're all now just slightly out of spec somewhere around .012" intake and .025" exhaust. Next will be the cluster and then I might start doing something about the rust.
