Air jet settings 1975 Wing

[jeffk]

Thanks for your feedback. I have another question. I set the air settings and synced the carbs, it seems to run pretty good now but above 4K RPM's I don't seem to get any more power it just bogs down a little. My plugs are a little black and sooty so I am running rich. What is the best way to lean things out a little.

Check your air filter first.
If you have the correct air jets and they are in the right place, you don't need to do any more with them
#60 nearest the plenum, #120 nearest the inlet manifold, #110 in the brass elbow.
Next check your float settings; 21mm from the edge of the float chamber to the top of the floats. The floats should lie parallel to the edge when JUST touching the spring loaded pin on th float valve.
Make sure that pin is working too: http://www.wingovations.com/float-valve ... 4591640610

Finally, check the ignition timing. A stuck advancer mechanism will stop it revving.
