Title: Mpg opinions
Post by: Cypher1982 on July 29, 2020, 10:28:22 PM

Filled up today, as nodded with variator boss, opened up carb air inlet tube from box, smoothed carb face, drilled main jet out to approx .90mm, and running open air box.... seriously, the best it runs is with the airbox lid off and I secured the filter in place. And needle shimmed about 1mm... the shims are a bit wonky.

Anyways today I filled up and calculated 102.5mpg. That's basically WOT everywhere. I dont think that's too bad. But i know if i remove the shims...it runs like crap, if i restrict air more....it runs slower. I build an air scoop that basically forced air into the factory filter, but it ran slower... but then again, it may have started to go lean.  Got a plug I'm gonna to a WOT plug chip with. But it still seems like it wants more fuel... anyone have any thoughts?

I have a new diaphragm and needle coming this weekend to see about further adjustability.

I'm envious that's all. Wish I got at least the performance of a Nissan Versa for the fuel I'm burning.

Yes, have to factor holed pistons into MPG equation.
