I don't seem to have continuity from the spark plug holes back to the brass screw when the points are closed. I spin the rotor but no plug wire is hot. How can I test for a misaligned coil? All parts are new except the dist. cap. This is an early 8N Front Mt. [Reply]   [No Email]

Not sure I'm following you here....... Are you checking for continuity between the holes in the distributor cap (where the plug wires insert) and the brass screw in the distributor? Because if you are........you're wasting your time. The rotor never touches the brass nipples in the cap. It's a HV connection. 75 Tips [Reply]  [No Email]

If all of the continuity checks are OK, where can I look next. With the distributor installed on the tractor I never get spark. Believe it or not, this tractor used to run before I started messin' with it. I WILL NOT GIVE UP! [Reply]  [No Email]

Did you put the distributor & coil back on the engine as a unit? Do you have battery voltage at the top of the coil? Keep at it....... [Reply]  [No Email]

No luck either way. I have voltage to the top of the coil. I know I've read somewhere that the wire to the top of the coil must be a minimun size. Unfortunately I don't remember what. Is there any other component that might affect the spark, ie., the alternator? BTW many, many thanks for taking the time to respond. Untitled URL Link [Reply]  [No Email]

It has nothing to do w/ ignition. Don't worry about wire size; you either have battery voltage at the top of the coil or you don't. Make sure the battery is fully charged. That's critical. Do you have a spark checker or are you using an old plug? In other words, tell me exactly how you are checking for spark. [Reply]  [No Email]

I was checking the connection of the coil to the dist. The spring was contacting the brass screw ok but I noticed the silver tab on the coil did not touch the contact "button" on the dist. cap. I tried bending the tab a little but I broke one off in the past so I'm very cautious now. I'll keep trying to align the tab to the dist cap button. [Reply]  [No Email]

The tab on the bottom of the coil not making contact w/ the brass button on the cap. (With the cap on, the tab must firmly contact the brass button. No contact = no spark.) Chances are you found the problem. 75 Tips [Reply]  [No Email]

While each N has it's 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 an updraft carb w/ a gravity fuel system; it is by it's very nature subject to flooding. Too much choke makes it happen. 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. [Reply]  [No Email]
