    9n tractor timing

    You mean I'm NOT the only one???

    Is it possible for timing gears to 'slip'?

    ...and how does one determine TDC on a flathead? (early 8n front-mount)

    8n Advance weights...

    Nothing about this makes sense, and I don't have any more ideas, so I cheated. I widened the adjustment slot as much as I could without moving the coil contact out of reach (A homemade jumper with a bare lug on that end insure the coil's spring thingie will connect). The points still didn't...

    8n Advance weights...

    I tried to start the 8n in sub-freezing temps. Starter broke. Fixed that. Now it cranked good and tried to fire, but wouldn't start. It was getting fuel, spark, and compression, but still wouldn't run, so I figured it had to be timing. When I pulled the distributor, the leaf springs were broken...

    8n Advance weights...

    JMOR, your suggestion to use some of the old + some of the new was a good one; unfortunately the new weights won't fit onto the old shaft. I may try turning down the old shaft to fit, but I'm losing confidence that the timing problem is actually in the advance assembly. I clamped the drive...

    8n Advance weights...

    Thanks for the pictures. I didn't realize they were indexed with a 'flat' like that. Are ALL of the replacements built with the slotted plate upside down (meaning 'wrong')? Am I the only one who can't make it work? Thanks again. You forum guys have been a great help!

    8n Advance weights...

    I bought it from Yesterday's Tractor, who has told me that they've never had a problem with that part but that I can return it if I want to. Well... More confusing yet is the fact that every picture I've seen from other suppliers seems to show the same orientation as the replacement; namely...

    8n Advance weights...

    Thank you for the offer to upload the picture for me. I've attached a copy [phone camera... shaky hands... not proud of the quality]. This is Dad's 8n. He's had it for 50 years, and I've worked on it since I was a kid. I thought I knew a lot about it, but I don't understand why I can't get the...

    8n Advance weights...

    I re-bushed this front-mount distributor and installed a new advance assy, and now can't get the static timing right. Took it apart again and noticed the slanted guide slots on the bottom of the weight assembly are canted in the opposite direction from the original. My poor old brain can't...

    8N point gap...

    Thanks, JEKI, what you said sounds just like my problem, and your solution sounds just like what I'll have to do to fix it. I guess we have to expect some wiggle with replacement parts... after all, the thing is 60-something years old.

    8N point gap...

    Wow, you guys are FAST... Yep, it's a front mount, and yep, they're cheapo points {I guess} that I bought at Atwoods and Tractor Supply Co., but since the problem is identical with both sets {5 years apart}, I figured I should look somewhere else for the real cause...

    8N point gap...

    I can't get the point gap even close to .015. Cheating it every way I can think of only gets the gap to about .030. The last time I replaced the points, I settled for that and the tractor 'ran', but it's only been 20 or 30 hours and now, no spark, so I'm doing new points again and running into...
