I forget. Which way does the adjustment go on the hair spring to make the speedo read slower? Mine is about 5 mph fast. I think it goes to make the spring shorter, away from the fixed point. I test the speedos with a drill motor using the right rpm to read in the normal range, about 50 mph. If after it is adjusted, it reads 5 mph slower at the same drill motor speed, then I know I have fixed it.

Or, if it reads 5 mph faster at the same drill motor speed, you adjusted it the wrong direction...

I have a Waltham speedo on my '30 Roadster and it reads about 5-7 mph fast also. Is there any adjustment on the Waltham unit?
 
I had papanick rebuild my frozen stewart/warner oval speedo. Great job, everything now works, speed is accurate, looks good, faster than fast turnaround. Got a round speedo I'll be sending after my blown off garage roof is repaired. Hate the rain and wind! From "sunny" California.
 
I had the same problem of a slow speedometer and odometer- 5.4% slow and low. I fixed it by changing the speedo gear from a 19 tooth gear to an 18 tooth gear (less teeth=faster rotation). My unit is now "spot-on" as verified by radar and highway mileage markers. Worth a try. Good luck !
 
Ellerman Speedometers out of Wichita, Kansas (316) 722-2107 has done several for me. He's a member of MARC & MAFC and advertises in the The Restorer & Model A News. He's also doing a seminar for the High Country Tour in Breckenridge, Colorado in June.
