Need Troubleshooting Help - Carbs, Timing?

[BPT]

I was very surprised but the leads looked very good to me. No corrosion and nothing but shiny copper that I could see.

Well I think you'd be a much happier man if you replaced that grey crack-o-matic BPT, I've got nothing but praise for the Dyna coils, I just cleaned out a socket full of corrosion in a 1994 Dyna, it came up nice shiny and it's firing just fine.  I think it's the cracks in the original grey coils that are the problem, let in moisture that lead to shorts in the windings but good the towers were dry, probably has hidden the problem for many a year!

[BPT]

Yes, Tunnelrider, definitely replacing it. I'll order an orange Dyna today. I know the one I have is just a problem waiting to happen. Hopefully it might take care of the problem I'm having now.

Hi BPT, i had a sort of similar problem a while back. It turned out to be HT leads. Check out my old post '   HT leads    '

[BPT]

I looked at that post, wow, a lot of that was exactly what was happening to me.  I'm ordering a coil, I have a spare ICU on loan, and I'll probably go ahead and get some new wires just because.  Mine look ok but i guess it's best to get that out of the way.

If you want to build your own wires I have some extra NGK ends "in stock" and maybe some wire.  If not you can probably get some solid core wire from NAPA...

[BPT]

I wouldn't mind doing my own, Justin. Looks like it will be next week before I will get a coil anyway.  I looked on Aircraft Spruce after reading what you posted but couldn't find the wire you mentioned (it was late and I was tired though).

I have a NAPA close to work, I was going to call them today about something else, I can ask about wire. How much for your ends? Or do you know anywhere local that carries the correct pieces?

On a related subject, are plugs like oil (an opinion laden discussion)?  I have Bosch W6DC's now. I see these are no longer made, available if you look hard.  EME has the R version but I think these aren't supposed to be used in mine?  I'm not trying to change anything, just want new plugs.

[Justin B.]

The only difference in plugs is the "R" plugs have an added internal resistor.  Seems I remember from years way back, when resistor plugs started becoming fashionable, that the resistor provided a bit of RFI supression.  As has been pointed out the internal resistor is irrelevant compared to the resistance of the "air-gap" at the plug end.

PM me on the NGK caps...

[Bob_Roller]

NGK has non-resistor plugs available .
I think I have BP7ES in the R65's

[mrclubike]

the best way to buy the wire is just ask for a universal 4 cyl plug wire set
Just make sure they are solid copper core
They are used on industrial and tractor engines
You will have enough wire and and coil ends to do 2 sets

I know our local motorcycle shop has NGK 5K boots in stock

Also N7YC  Champions are still available for a non resistor plugs

[BPT]

You're right Bob Roller. I talked to EME today and they told me only BMW has the Bosch's now (unless, of course, you find old stock somewhere). He recommended the NGK and said they've has no problems or complaints.  I know NGK makes a good plug (they're preferred over Bosch in my GTi), I just wanted to make sure I got the correct replacement.  Since I'm chasing down problems I wanted to keep changes to a minimum.

I didn't realize they weren't made anymore and I'd just talked to my local shop people about plugs 2 weeks ago. They recommended those and now I'm going to have to mention that to them.

Like this set
It is from Orielys and it is enough for 3 sets of airhead wires

[BPT]

Thanks again, MrClubike.  I'll check out the stuff you've mentioned here.  I went ahead and got a set with the coil and stuff that I ordered but would rather do my own so that'll be what I do next.

Very strange, once again I've made a post here and then come back later to find a post of yours above mine that wasn't there before.  It's happened several times the last week or so.
