Hi Everyone, Working on my '96 Spcn Heritage, 80", Ultima ignition, Ev-27 cam, 2 into 2 pipes,.050 shaved heads, modified Keihin Cv carb.
I bought this Cv carb a couple of years ago. It already had the Cv performance kit installed in it. It runs real good, except for being able to "Trim" the idle mixture correctly. Today I found out that the Pilot jet is a #48. I can turn the idle mixture in slowly all the way in to it's seat, and no change in idle quality or speed! So..I went to a #46. Now...I have to turn mixture out about 5 turns to get any quality idle. By now it's ready to fall out of the carb!
So...Back in with the #48 I guess. Since #47's are not available.
One thing I'm wondering about...is a little "o" ring on the idle mixture screw. If it was missing, what would the negative effects be?
Any thoughts? Thanks! Doug
