Ok, second drive started off fine, oil light no flicker when she's cooled off..
Sounds: 1. Lean 2. Over Advanced How many clicks off of black smoke is your mixture set @? It feels now like it wants to be shifted just under the power curve, and it pings in a 200 rpm range starting at 3k. Maybe I can string together an a/f meter from paperclips, and dustmites? I hope the oil flicker isn't bad bearings... (IMG:style_emoticons/default/blink.gif) 62 miles isn't better than 4800.. M |

A shorted or dead CHT results in a rich mix when starting up and running like a pig. If it starts up fine and gas isn't pouring out of the exhaust, rich running mixture is usually caused by the MPS. The MPS controls the running fuel mixture and you have a unit thats been played with.
Sure, someone could have cranked the fuel pressure way up but thats very usual. Geoff |
