    Any tips or tricks to get a 440 motor running and stay running?

    Would bad timing cause a no start ?

    Air, fuel, spark.............I get it

    I have fuel at the carb.............How can I test spark, by myself?

    I was able to get the motor running for 5 seconds, it sounded good, then died

    All it wants to do is crank...........novice looking for help

    Thanks!

    Is this a new build, or had been running "right" and now won't? And what is it in, year, model, and what do you have for carburetion and ignition system?

    Checking spark...........rig a "gap" either a spark tester or a plug to the coil tower and ground. BEST to use a solid core wire and not radio suppressor wire. Crank the engine USING THE KEY and that is important

    With a solid core wire, you should get nice blue snappy sparks at least 3/8 and typically up to 1/2" or more long

    How 'bout cam timing? How did this all come about.........IE did it act up and run rough and then won't start, or did it just stop, or what?

    Have you checked compression? I try to check both compression with gauge, and do a leakdown, the two go together and may help a lot to diagnose

    Have you examined the plugs? dry? wet? Have you inspected the dist. rotor/ cap for dirt/ moisture/ carbon tracking etc?

    How do you know it's getting fuel and IS IT FRESH and IS IT PROPER?

    (Decades ago a then friend was priming down the carb throat, new build would not fire, turns out HE WAS USING JET FUEL (kerosene)

    Yes, new to me used project vehicle I am trying to get running

    Fresh 93 octane fuel and new fuel filter

    There is fuel in the fuel filter and I can see fuel spraying down into the carb (rebuilt by Woodruff)

    New MSD ignition system, new Carter Strip Street pump.......motor less than 200 miles on it

    How about some answers and results for topics in post#2?

    Can you post decent pictures of the components and wiring?
