What makes 1 engine have better mileage than another?

Tune for performance not temp. If you are getting your best performance and your temps below 200*F. Which happens a bit if you run in colder temperatures. Put a little tin foil over the cooling head a little at a time until temperatures reach over 200F. This technique can help with break in on motors as well.

The way the crank shaft is cut to atomize the fuel and what pipe is used. With the same driver on the same track and truck/buggy with the same tires ETC, only changing the 2 things mentioned up top underlined, you can see 1-2-3/4 to 3 min longer run time. EDIT: tuning accordingly as well.

I see you have a MBX6, do you steel have the black insert in the fueltank if so remove it.
As for the os2060 on your engine, i liked it alot wen i was given a Alpha F850 to test it out.
Fuel mileage and overall performance was very good with that pipe, pitted at 10 min in the one race i used the engine in a MBX6T.

I am not sure about that one...the fuel is atomized as it leaves the venturi of the carb...any contact that mixture has after that actually causes separation of the mixture...I don't believe a crankshaft will atomize the mixture...more like a properly cut crankshaft will offer the least amount of contact with the mixture as possible and cause the least amount of separation possible.....
That's how I should have worded it. I just figured most would know the difference in a factory mass produced crank V.S. a nice cut moded one. I run a moded speed and the difference in milage is huge.

Throtle EPA
I can't believe that no one has made mention of adjusting throttle EPA. I run mine at 75% on a large track and I get plenty of power and just over 12 minutes a tank on my B5/2013 combo in my 6T.
Once you have your tune dialed in, adjust your EPA's for that extra bit of run time. Most people completely overlook this!

personally I don't mess much with crank shape on the counterweight...it causes too much vibrations......if anything I add weight to the counterweight if the engine isn't already slugged...
IMO head button can make a huge difference on mileage... Carb design is also huge......transfer port orientation is also a big factor when it comes to mileage...The engines we do here at Clockwork almost look 100% stock from a visual inspection, but they get substantially better mileage then stock and also make substantially more power.....

button on my radio set up for dual rate throttle EPA's.
I can press the button for full throttle, if I want it.

I think the problem here is completely tune related.
