This 109 has a dished "de luxe" bonnet. I don't think your problem is too much air. Slow response is likely worn seals on the accellerator pump piston (could be leather) or the accellerator pump linkage not set right.

[QUOTE I think I am going to keep it. It is going to work better with an air filter. Now it's not responding right away. Too much air.
Do you have a de luxe bonnet? Or the flat one.
thank you
