<div>Ken-it sure sounds like a fuel issue. You are dumping a lot in with =
rich needles and wide open jets but not getting results. I only use clear =
gas (no ethanol) and add octane boost and Stabil to 5 gal mix.</div>
<div>I read a lot about folks moving the timing to 17 degree <span =
style=3D"text-decoration: underline;">advance</span> for best running but =
that does not seem to work for you.</div>
<div>Lifting that mixture pin is =
not always a good barometer as it only takes 1/32" to get the reading and =
it is difficult to do that with the pin. SU rods in the dashpots using the =
thin bars are a better adjuster as you can "see" 1/32". Colortune also will=
give you a reading.</div>
<div>Another suggestion to increase burn, is =
electronic ignition, which may give you a hotter spark. The days of 101 =
Octane fuel are just a faint memory for these cars. Dumping the clutch when=
shutting off will stop overrun. Hank</div>
