00_Shee Posted September 23, 2013 Author Report Share Posted September 23, 2013 Checked compression; ~125psi each cylinder. Carbs appear to be synced when I look through intake window; not sure what type of plug caps these are. In the process of testing the coil now. Today when I checked the harness I found a section of my wiring harness that had been touching my silencer and the red/white and green/white wires coming from the stator were melted and slightly exposed and touching the pipe. Hopefully this is the reason to my problems. Also I used a multimeter to check the stator and coil. Here's a video of me testing my ignition coil. I'm not getting readings in the ranges listed in the Clymer. I got numbers that fell within the range of norms when I tested the resistance on the stator and coil pick up. Are these readings I'm getting indicative of a problem with the coil or are these readings wack? Quote Link to comment Share on other sites More sharing options...
00_Shee Posted September 23, 2013 Author Report Share Posted September 23, 2013 Has anyone gotten numbers similar to those in my video? Quote Link to comment Share on other sites More sharing options...
00_Shee Posted September 24, 2013 Author Report Share Posted September 24, 2013 Seems to be running good again for now. I rewired the harness and freshened up the spark plug wires connections. Hopefully this was the solution. Only had time to run it for about 10 mins, but it ran flawlessly once again. Not sure about the ignition coil resistance numbers I was getting? O well. Thanks for all the suggestions guys. This forum has helped out a lot in the little time I've been apart of it. Quote Link to comment Share on other sites More sharing options...
kedge82 Posted September 26, 2013 Report Share Posted September 26, 2013 fyi backfiring is not sign of rich but sign of lean do you have adjustable timing plate? if so checkand make sure blots are still tight and it has not moved. Quote Link to comment Share on other sites More sharing options...
Brap_Life Posted September 30, 2013 Report Share Posted September 30, 2013 (edited) did you let it warm up and then test compression? a lot of times metal will retain it's original shape when cooling down, but when heated up the warping will show. But if it was warm during the compression test it should be good. Just remember to have the engine at it's trouble temp when diagnosing. and yes, a flying short can happen, just the slightest expansion of metal upon heating up can cause the stator to short a leg. but your stator doesn't run your ignition, your pick up coil does. EDIT---just scrolled back up to your video section, brother, your pickup coil leads are green/white and red/white. That's exactly what your problem was, intermittent shorting of the pickup coil. re-route and re-seal that section of harness and ride on.
