Hi Bart!

Without actually looking at it directly my first guess would be that one of the gears is broken and might have a tooth missing on the tripometer. Stopping at 29.9 is very odd though.

Second guess is that something is slipping and not allowing all three digits to roll over.

Third guess is that the trip reset mechanism is somehow interfering with proper operation.

Another popular failure item is the lead gear on the odometer this typically manifests as lack of odometer mileage registration though.

Thanks for the plug parshoot1!
