help solve problem

Very common problem. Not enough fuel at WOT. Problem can be too small jet, needle clip height, or what I think is slightly more common: carb float not properly adjusted from factory.

my carb is slanted about 15 degrees because the throttle cable doesn't fit under the top tube of my bike, would this cause a problem with the carb float?

Does it run good?

Yes, up until its at WOT then it staggers.

I don't think 15 deg is enough of an engle to cause problems. I'd adjust the float and then increase jet diameter. In addition, the more oil you put in your fuel, the less available gas you have to burn per unit volume of mixture. Try a 40:1 mixture using a quality synthetic or Maxima 927. Running 16:20-1 is just too much oil and can be effectively leaning your mixture out.

You may be having a problem because the flost chamber is not level. It is designed to have a little extra fuel at lean angles, but since it's constanly "leaning" you may have a little fuel starvation goin on there. Have you tried ajusting your float arms upward a little?

16-20:1 IS too much oil. 24:1 is recommended for a reason...these are ancient tech piston ported engines and they also have really sloppy tolerances. The highest I'd go is 32:1. And that's at your own risk.

good morning all... so far this forum has helpd me some what with the minor problems i had...one recent prob. i had was my air filter fell off as i was on my way to work. i realized it when i was trying to chain my bike up to get a bite to eat. i retreaved the air filter cap about 2 miles back. it was slitghtly damage. the bike will not run now with out it. the cap is the only thing that fell off.. any suggestions.. any home aid remedies out there i can use to get her back on the rode??

Did you find the filter element or just the cap? You need both. Try making a new one from an air filter element for a mower and fix the old cap.
