Sorry this is so long winded, but I can’t seem to make it any shorter…
So, I just finished rebuilding the carbs, and she started right up. Thanks Randakk for the great rebuild kit and Howard Halasz for the guide. I also bought the colortune along with the Morgan carbtune, so I could finish the job. I’m amazed that she ran at all with the things I’m finding that need attention.
A little history since I bought her last year. I did a front end renewal, rebuilt the brakes and forks, new tires, changed all the fluids, and finally got to ride a little before summer ended. I didn’t realize I had bought as much of a project as I did. I’m still fairly new to Goldwings but, Experience is the best teacher…
Anyway, I still have a slight misfire/backfire while she’s cold, but it seemed to disappear once she warmed up. Which is what she did before I did the carbs. So, I figured I’d adjust the idle mixture with the colortune. I got set up and found out I had no spark at #1, took a breather, re-installed the plug, got my timing light out to check all the cylinders. I have spark at all the plug wires. I then disconnected each plug wire to see what response I’d get. #1 didn’t affect the engine at all, and #3 only caused a slight stumble in the idle. #2 & #4 definitely affected the idle when disconnected. I then decided to check the resistors in each cap, only to find #1 & #3 are missing the springs behind the resistors. Along the way, I found that #2 & #4 caps are cracked and need to be replaced.
After doing some searching here I’m a little more confused than when I started. I found a thread that says the ’82 & ’83 don’t have resistor caps because they run resistor plugs (DPR8EA-9). As far as I know the ignition components are all original. Any help would be great:
What type of caps do I need to order to make this right?
Could the missing parts / weak/no spark on the 1/3 side be causing the cold idle misfire/backfire?
If I use resistor caps, should I use non resistor plugs, or stick with Honda recommended?
Thanks,
Mark
