# 4 cylinder misfire
Didn't have time to stay in the garage tonite, have to be gone next few days but was digging into 'why' the Roadster was running under powered and missing.
Cleaned out sediment bowl, blew out fuel line, and took carb apart and blew it out not a speck of dirt. Gasoline is fresh. Strong fuel flow. Started playing with the ignition side, checked timing, point gap, all fine. Took out plugs from front to back, numbers 1-2-3 looked good all gapped at .035 took out # 4 plug and it was wet from gasoline, not firing apparently. These are Champion plugs I put in last fall, going to put back the set of Motorcraft TT10's I took out and try for a spark test to track down the why. Have backup dist. body, rotor, and cap When I can get back to it I'll re-post what I find. Out of time right now. Forgot to add,,,, left out #1-2-3 plugs and cranked engine by hand, and had fairly good compression on #4 w/ that plug in. Seemed normal anyway.
