I need disc brakes...
My engine sounds like it knocks...
Doesnt idle well...screw doesnt do much...Ive adjusted the carb severl times...
Dont think I get 100 MPG...
I can got 27 MPH...
o and the fuel filter only has a little bit of gas in it all the time...
20:1 mix...can I go with 32:1???
anyone have any comments on those things that would be great!!!
other than that I think it runs great!
BGF = noisey crappy motor
I usually get about 80 mpg till after break in and tuning. Then 120
27 mph is about right for 44T
Air in the fuel filter is normal
If it's an NT carb run the needle clip in the second to the top position.
With a new motor go with 24-28 to 1. You can go 32:1 after a couple gallons.
NT carbs usually come jetted rich. After break in drop it down to a 68 or 66.
