I have fuel pressure on a gage at the carb that bounces between 3 and 9 psi quite rapidly. I put a new gage on but got the same flucuation. Someone said it was air being sucked-in. any comments?

I had the same problem this year.
I wasnt venting the fuel cell very well.
I made a few changes on my vent tube and the problem went away.

Mine would jump around all the time,and really run horrible out on the track.

make sure your vent hose isnt not plugged,or if you run some kind of filter on the hose,replace it.
Hope this helps
