Hi guys, I have a question about fuel consumption. Mine seems very high to me.
I read here in the forum that this should average 16-18 mpg. Mine is around 12 mpg. I find that a lot. Where to start looking for the mistake?
The ignition is set according to the manual. The adjusting needle is open a maximum of a quarter turn when the engine is warm, but consumption does not decrease significantly on longer tours.
The spark plugs don't look too bad, but the exhaust blows against the rear axle, and there is a thick layer of soot hanging there.
The CO value has not yet been measured.

The real question I wanted to ask is whether an electronic ignition or a centrifugal advance distributor have a positive effect on consumption and reduce it?

I also have a Tillotson carburetor on the shelf. A Zenith is currently installed. How would a change work?

Greetings from Berlin
Andy
