Starting issues
Starting issues
I seem to be having intermittent starting issues on my 430. Sometimes it cranks over and starts like a champ, then all of the sudden it seems like the starter does not have the umph it needs to roll the engine over at all. Earlier today I went to start it for the first time in a month or so. It cranked over great, but did not fire. I realized that it might not have any gas, and I was right. Poured 2 gallons of gas in and attempted to start it again and now it will not roll over at all. It has a new battery, new wiring, new starter & ground cables. I believe that I have good clean connections on both cables. The engine has been bored .090 over and has less than 10 hours on it since rebuild. Does it sound like a weak starter? Or does someone have any other ideas. Thanks Dave

if only ten hrs. i would try turning by hand and see how that feels make sure you don't have any internal problems then start at the battery and go from there check every thing again

Ground or connection issues, defective battery cables, too small of cables, bad starter, too small of battery are all possibilities. Check your timing just in case.

If it's not rolling over at all, sounds like starter solenoid problem. If you try to hold the starter engaged, does anything get hot or start smoking? gregjo1948

If your battery is charged, cables and connections are good, I think I would bench test the starter. Just because it's "new or rebuilt" doesn't mean that it's not defective. gregjo1948

I agree, I had a fresh rebuild do what you are describing, and there was an internal short.

As gregio said, it could be the solenoid. The little pyramid shaped box on top of the starter has the main battery cable attached to it and the pull rod from the starter knob. You can take the pyramid cap off by removing the two small bolts with a stubby flat blade screw driver (or just remove the starter to work on it - easier).
The electrical starting contact is made by two plates of copper metal being pulled together when the starter rod is pulled. You have got to love the simplicity of 1960's. Take a file and aggressively smooth out any pitted spots. Follow the same contour and verify a good contact by pulling the lever and seeing how the metal plates align. This is something you should do about every 5 years or so anyway.
This may not be your problem, but if it is, it will exhibit symptoms just like you are experiencing. Also I would follow Duke’s advice and remove the spark plugs until you get the engine turning properly. Gil
