Atomic 4 wont start
I have an atomic 4 on my 1971 C&C 35. It was running fine yesterday then it just shut off. It turns over but won't start. I cleaned the plugs and wires, changed the ignition coil and still nothing. Any ideas?

Did you test for spark before changing things? Check for spark after? Is there fuel in the carburetor bowl?

I replaced all of it long ago, the tank was rusting from the inside out and the fill hose was falling apart and dropping rubber bits in the tank. Even more fun was when the rubber 90 degree elbow came apart where the tank fill is Also did you check your work - are you getting a spark now? Joe Coquina 1973 C&C 35 MK I |

You need 3 things: compression, fuel, spark. That's it. You're likely missing only one, and it probably isn't compression.
Give it a shot of starting ether and see what happens. If you're missing spark, there will be no change. If you're missing fuel, the engine will run for a short while on the ether. |

very basic question, Al: How do you use starting ether? Where do you squirt it? (I've obviously never done this before.)

Do you seer the air filter sticking out the left hand size of the carb? Take that off (easily loosen the machine screw and slide it off) and give a 1-2 sec squirt of ether into the carb from there is what I do when I need to test it that way.

No need - the ether will spray through the flame arrester no problem. A little bit goes a long way too.

look at the carb, theres a small square flame arrestor with a black hose ontop - give it 2-3 seconds max.. open throttle 5%-10% (this gets the starting fluid flowing) - and swing her over and see if she puffs at all.
When you swapped the coil did you wire it correctly? should have close to battery voltage at coil + when key on before starting - check that too and report back.. |
