Making up for a bad winter

I have been bustin' my ass the last couple weeks trying real hard to make up for lost time due to cold weather and also trying to loose some of the winter "dunlap" I accumulated.. waiting on a block to come back from the machine shop so I took in some small stuff and did some much needed work on some of my own. Today I got a good 'un...a Hawk I know well is in with some funny noises... Go forward and stop...roll roll roll KLUNK...back up and the same thing...hmmm.....searched the trunk, under the seat, etc....nothing! Then I remember the owner telling me how he and/or local 'technician' put a new sender in the tank..and he was proud that that fixed his gauge without a trip to see me... It all became clear...those guys have dropped something into the gas tank...and whatever it is it is rolling back and forth... This will be interesting to see...... I 'm betting a socket or a screwdriver.... Studebaker George
