8N won't start with the starter

blinwmiaol.com · Jun 6, 2011

I am doing some work on a neighbors 8N, it just flat out refuses to start by the starter. I pull it 5 foot with my 4 wheeler and it is running like top. It idles well, doesn't smoke and there is no hesitation when going to full throttle. The tractor is still set up 6 volt and turns over as fast as most old 6 volt systems do. What do I need to do to get this thing to start on its own? thanks for any suggestions.

First off you will get more and better answers in the 9N/2N/8N forum down below. That said the problem could be a few things. The starter maybe getting weak and draws to many amps so that in turn takes away from the spark needed to start it up. #2 it could be low on compression and if so a rebuild or going with 12 volts is the only fix. Any thing less then 90PSI per cylinder it to low of a compression on those old flat heads. Oh and by the way letting us know if it is a front or side mount distributor also helps use help you

The tractor has VD.

Just a thought, but is the battery fully charged? A battery with less than a full charge will still turn the engine over, but there might not be enough electricity left over to supply the ignition.

Ignition is marginal and doesn't have enough voltage to light 'er off 'cuz when the battery voltage is pulled down by the load of the starter ignition becomes even weaker.

Clean up ALL electrical connections. With only 6 Volts it's even MORE important to keep 'em "clean, bright, and tight"!

A weak battery can aggravate the situation, as well as a weak ignition switch, worn breaker points or a weak coil.

Install 00 battery cables so the ignition voltage doesn't drop. Hal

Sometimes valves being adjusted too tight will hinder starting just enough that the old 6V's won't quite start it.

I have seen them do that if someone installed carbon fiber plug wires. For 6 volt systems stay with plug wires with wire in them.

For test purposes run a ground wire from the distributor back to the battery. Could have a lot of resistance build up over the years between the distributor and battery ground strap. You can also check with an ohm meter.

We had a 2N with this problem.

Try 12 volts. Lotta people do. Only as a last resort. Ask advice as to how to do this properly. Dave
