Re: No start. I think you're still running points in your 283, right? Sometimes moisture will prevent sufficient ignition. I've had some luck with spraying WD-40 (Water Displacement) in the distributor cap. It would be a quick "see if it works" approach.
Otherwise, I'm sure Sweet with come to the rescue. Good luck.
