Hey guys I have this weird stumble/sputter on 1/4 throttle tip-in after I decelerate. Say I ramp up the RPM's in 3rd gear, decelerate, and then get back in the throttle 1/4, it sputters a little.
Do you think this a pilot jet or needle issue? Do you think this is from being too lean or rich?
Right now the needle is on the 4th clip/middle which COULD be one clip too rich. It runs ok other than the stumble in the needle's throttle range.
The pilot jet is a 55 with the fuel screw only 1.25 turns out. It starts, idles, runs ok other than the stumble.
In this vid, you can hear it at 1:12-1:13, 1:14-1:15, and 1:16-1:18. Thanks a lot for your help!
