Gas guage
When I fill my tank up the gas guage will toggle back and forth from full tank to low fuel then when I burn enough off to about 3/4 of a tank it works fine with no problems. If dont put over 3/4 of a tank I would not notice a problem at all. Anyone else ever seen this before.

It may take a few to clean up the sensor

Yes, put another bottle in the gas. Sometimes it does take more than one to clean the sulfur deposits off.
