Poor gas mileage

[Richardt2k]

How long has it been getting bad mileage? Is your odometer correct?

Speedometer is off. But read faster. Witch if I go by that it’s even worse.
Put in used motor last October. Low mileage. https://youtu.be/JuxeNU-Fuls
Also rebuilt the carb.

Am I thinking backwards?
At 45mph on my phone the odometer reads 53mph

Still with the odometer I’m get like 9 mpg

Bob what does the adjust screw do at the carb??

There are 2 screws on the carb - Idle speed screw, Idle mixture screw.

Check what gear ratio you have.

Yes, that’s what I thought.
Got another complete rebuilt carburetor.
Going to give that a try.
Thank you for the info.

Ok. But I think it’s high. Like 3.54 because it dogs from 2 to 3 gear
