wilson24 Posted April 21 Share Posted April 21 When I purchased my 1924 Buick, the line in the Motometer was red all the way to the top. So, I started reading on this an other forums about how to repair it. Somewhere in one of the forums, someone said to spin it in a bicycle wheel. I don't know who said it but it worked! I flipped the bike upside down, put it on a table and secured the Motometer between the spikes, head towards the rim, and started spinning. After about 1/2 a mile, I stopped - there was no change. I figured I would give it another chance and I spun it for about another 1/2 mile and a higher speed. This time when I stopped, I saw one tiny bubble, that was not there before, in the bottom of the glass tube - maybe success? So I stated cranking again, left hand then right. At the next stop, there were 3 bubbles! More cranking at as high a speed as I could crank, Lance Armstrong would be proud, and there was one large bubble close to the top. More cranking, and success! All of the red was at the bottom and the top was clear. It only took 7 or 8 miles, but it worked. I have driven the car several times since then and the Motometer moves as it should. So, a big thanks to whoever made that suggestion. 12 Link to comment Share on other sites More sharing options...
pont35cpe Posted April 22 Share Posted April 22 I also have one that is red, may have to try this. Not sure what direction you mounted it, any picture? Thanks Link to comment Share on other sites More sharing options...
Glenn Manes Posted April 23 Share Posted April 23 An anecdote for all… Brings back the memory of Mom, or Grandma for you younger folks, shaking the mercury down in the thermometer before placing it under my tongue.. 1 Link to comment Share on other sites More sharing options...

Morgan Wright Posted April 23 Share Posted April 23 When my wife's grandfather was born they thought he was going to die, so they wrote "Boy" on the birth certificate. But he didn't die and his legal name was Boy. So they named him Boyce. 3 Link to comment Share on other sites More sharing options...

Not sure what direction you mounted it, any picture? Thanks No pictures but you mount it with the end that goes in the radiator, the "bulb", pointed towards the rim and away from the hub. That way when you spin the tire, it throws the red liquid back down into the "bulb". It will take several miles and a pretty good speed to fix it. 1 Link to comment Share on other sites More sharing options...
