  • 8N Timing
  • Tried to search archives but canít get the search function to work soÖ

    My 48 8N has 12 volt system and pertronics electronic ignition. It starts easy and purrs like a kitten at idle but runs rough when revved up and has diminished power. I just rewired the the whole thing including plug wires and added the electronic ignition thinking it would help with power. The tractor was pulling much better last fall when last used but now using it to blade snow and canít get out of First gear. The rewiring and ignition install improved it a little but not much. I took the carb off and cleaned itÖno help. I am wondering about timing? Donít know how electronic ignition might change that. I set it in the middle where suggested. Any suggestions appreciated. Thanks

  • Timing on a front mount distributor can be set with a timing light, BUT, it takes a lot of effort to exactly locate TDC-compression stroke on #1 and mark the crank pulley. If I didn't want to spend all the time and effort, I would set it up as far advanced as I could. I believe that will be best.

  • Don't know where you are located. If you were nearby, I would let you swap one of my working distributors into your tractor to see if that helped. One of the advantages of owning more than one tractor.

  • The reason the instructions say set it in the middle is because you cannot set the timing w/ EI on a front distributor. Unless you want to take it off, adjust it a few degrees and put it back on and see if it helps.

    Are you using suppression plug wires? Copper wires will burn up the module.

  • Jack, since GoDaddy moved us to a new platform, our ancient software has developed some challenges. When you search our archives, you cannot leave the forum selection at "all", you need to specify one of the selections in the drop-down box - something like below:

  • There is at ton of info in the How-To's forum here - here's one. 99.98% of all non-starting issues are due to mucked up wiring.
