  HI , The 283 is a great motor they keep on going and going- well as far as the dist. it is in right and wires are all good,etc. points,cond,rotor and cap all good. I would get some carb. cleaner spray type for the carb. clean it up good and also a can of cleaner to the gas. than I would check / change the fuel filter. Next I would adj. the carb. and get it as good as you can. and if you can not get any type of a adj. from it , than it is time for a new carb.
OK. or you could get a rebuilding kit for it.
