I have a 72 442 with a Rocket 350. Was running great till 2 weeks ago when it stated sputtering when I accelerated and then backfired a couple times. Took it out over The Weeknd for a short drive, stopped turned it off and now it will not start at all. Turns over just fine, spaying gas into the carb when trying to start and the filter on the gas line is good.

Any help greatly appreciated.

You need to check for spark. What distributor are you running?

Coil died?

Timing chain??????

Thanks everyone I will troubleshoot all above this weekend.

We'd be able to provide you with more useful answers if you gave us more information about the car. The mind reading thing still isn't working. Is the car totally stock? Has it been modified at all? If so, exactly WHAT has been done to it? Induction? Ignition? Wiring? All of these can contribute to your starting problem.

Fuel, air, spark

My bet timing chain gave up

If still running points, check dwell and timing. It could also be a bad condenser.

It cranks.
It has fuel.
Now check for spark.
If it has spark, check the timing (a timing light will work when you crank the engine, so long as you have spark).
If it doesn't have spark, figure out why.

Has the car sat? How old is the fuel? I would start there. Of course check the spark. I am curious how old the gas is. Carburetor's sitting for a long time with today's fuel creates issues.
Just my two cents.

Thanks, I drive it every weekend and I gas it it once a month.

And, you said it’s completely stock….which means it has contact points ignition correct?

All, thanks for all the help, turns out to be a broken coil wire! Runs great now.

Glad you found it.
