Another 8N Flooding

8N-MW

Member
I have a 1948 8N, 6V, Front-Mount Distributor. When I bought it, it was a weak sounding start. I did the oil, oil filter, oil bath air cleaner (even cleaned the mesh), cyclone bowl and ignition kit (plugs, cap, condensor, etc...).

The thing [i:4d5d02cd60]runs[/i:4d5d02cd60] great. It's been a little work horse for me in pulling logs out of the woods.

It also [i:4d5d02cd60]starts[/i:4d5d02cd60] great, sorta. It will start perfect, on the first or second revolution from the starter. [b:4d5d02cd60][u:4d5d02cd60]But[/u:4d5d02cd60][/b:4d5d02cd60], if it doesn't start that first time for whatever reason, I'm screwed. My starting process is Nuetral, 2 full turns of the sediment bulb valve, turn the key, clutch in, PTO off, 25% throttle, a tiny amount of choke and then push the button.

This makes me think it's flooding. Like I said, if it doesn't start the first time it's done for the day. Last time, I did some investigating. I pulled the plugs out and they were dry. I drained the gas out of the carb. I checked for spark. I tested the battery. I jumped the starter directly with 12V. There isn't anything that will get that thing to start if it misses it the first time around. I usually have to wait [i:4d5d02cd60]at least [/i:4d5d02cd60] 6 hours which is not acceptable.

This winter, I plan on taking the whole thing apart and going through it. I don't plan to parade restore it necessarily, but to bring it back to it's originally working ability ([i:4d5d02cd60]without[/i:4d5d02cd60] going 12V, pointless ignition, etc....). I'll do a new harness, dig into the engine a bit more, rebuild the starter and generator, etc...

In the meantime, what do you all suggest I do?
 
Keep your same starting procedure with one exception..., leave the choke off for the first couple of revs, if it doesn't start, add a quick pull of the choke and then back to off. I think that will do it.
 
hawkmiles........keep yer itchy-twitchy finger off'n that handy-dandy spring loaded choke knobbie. The drill is, 2-turns on the glass filter knob, ignition key ON, 2-rumpa-rumpas on the tranny starter push button switch and then....a quick pull on the spring loaded choke knobbie. Shud kick rite off. Iff'n you've FLOODED yer engine, change yer sparkies. Recommend NEW DRY AutoLite 437's gapped 0.025. Don't throw yer FLOODED sparkies away, just clean'n'dry 'em, one atta time in HOT runnin' engine and save'um fer the next time. (and there will be a NEXT time) As fer waitin' 6-hrs fer restart, thats un-acceptable to me too. It does take about that much time to DRY out a FLOODED engine. Me? I'd just change to NEW DRY sparkies. As a reminder, yer weird 4-nipple front mount dizzy is designed to be removed from the engine and have the points (0.015) replaced on the kitchen table. Just un-snapple the capple and remove the 2-bolts and walk to kitchen. The 2-bolt scheme means you kenn NOT install outta time. Installation is a reverse of the removal...except...finger start the 2-bolts, install the rotor and rotate the rotor until the OFF-SET tang fits the OFF-SET camshaft slot. Now tighten yer 2-bolts and re-snapple yer capple. Simple, eh? .......Dell, yer self-appointed sparkie-meister
 
As Jim & Dell are telling you, the likely cause of your problem is your starting sequence.

While each N has its own starting sequence, none of them will start well by just yanking out the choke rod & holding it out for 5 or 10 seconds while the engine cranks. This is a gravity fuel system on a low compression engine; it is easily flooded by too much choke.

Try this:

Key on, gas on 2 full turns, clutch in, 3/4 throttle, press the starter button. Let it crank for at least 3 - 4 seconds before you pull the choke rod. Then, don't hold it out for more than 2 or 3 seconds.

If you flood it, either wait a few hours or change the plugs. If you flood it, they're fouled & it will be it next to impossible to start. You don't need to toss them; heat the tips for a few seconds w/ a propane torch to burn off the invisible spark-robbing deposits from today's additive filled gasoline........or wash them in lacquer thinner or carb cleaner.

If my 49 has been run within two weeks I don't even have to touch the choke lever. Ignition on - put in neutral - hit button fires right up.
