[QUOTE="T-Rex Jeepster, post: 440015, member: 19821"] There was a guy that is a well known hot rod tuner that tours and races in the big leagues...Knows his stuff. I set the crank mark at 8 BTDC and then set the distributor to #1 at his suggestion. Ran great for more than several thousand miles with no issues and stayed steady at 21 MPG through many tanks. Gears and chain were set to marks. Then changed distributor, Went back to TDC on crank indicator and she just wasn't "Right" Almost like a de-rated setting. Pulled the distributor again and went back to 8 BTDC and she'd start, Idle like silk but wouldn't take any accelerator without missing and spitting. Changed the CPS and everything went perfect....For seven miles and then lost all "Timing" Then died outright. Let her sit, Cranked up but again would take any throttle.... Killed it, Got a tow back, About an hour elapsed and when I cranked her up to get her out of the driveway after getting dropped...She starts right up, Takes all the throttle and goes up and down the road like champ for about five minutes...Parked her and came her to hopefully find out why.... Gonna take your advice and change the coil and see if that stops the delayed action F' Up...And that's what it is behaving like...A coil with bad/thinned oil. [/QUOTE]
