So I tested that ignition lead before I fitted it to the old coil and found no continuity between the lead and spark plug cap, is this normal on some caps? Are they designed to spark inside or something? I removed it from the lead and tested the cap by itself and the circuit was open between the...

I dropped into town today and thought I'd take the coil and get it tested at the shop on my way past - they said it was fine right out to 11mm gap so no problems there. He said it is probably designed for CD ignition and wouldn't think it would work on points/condenser. Interesting I get such a...

Stumbled across that craig, that worth buying? Did DS80 put their funny $170 coils on LT80s? http://www.trademe.co.nz/motors/motorbikes/parts-for-sale/electrics/auction-627859165.htm

It's black I think, not sure about stripes. It's the wire that used to connect to the same terminal on the old coil and it ran like that... The old coil had about 1.5ohm with that same test. Have I bought the wrong coil..

I couldn't get the thing to spark when I put the new coil in today, decided to test it and found this... (0.3 ohm across primary coil) Problem is it? What are the chances it came off the factory line like that? What are the chances I did it.. I get 6V on the live wire from the stator on a...

Yeah I remember when I got that 3 million ohm reading or near about that I was talking about, it only worked with the probes one way, it must have a diode in it. I couldn't get it down to 1 ohm though. I won't bother testing again though it goes well. So... how does the DS ignition work then...

Motodevo, you're not talking about down here are you lol? Guess the chain was sloppy at some stage, the panel is rubbed clear. We may never know heh :( Any other way to tell? They got antique value or something? OK Craig good to know, I don't need the new coil but I like to understand! :)

You're right yeah, Keihin C100/CZ100 carburettor. Spot on man thanks for your help I found an exploded view that's what I was after. And with that coil in the mail that is my problem wrapped up I think. You're too good Craig jeez I owe you a beer or two don't I

Yeah, that's closer to it. Although my plug is on the other side... Just out of interest... That coil wouldn't have worked on the DS80 right...? Because it doesn't have the CD integrated? Are there generic coils that would have or is that a pretty unique design

Nah, not even close. I'll take a better photo for you. It's orientated strangely it sits on top of the cylinder with the intake facing upwards, slide pulls horizontally. Float is a tall tube parallel to the venturi. Will take a better photo... Got a coil in the mail. Not gonna piss with that...

ehhh beat me to it..

http://www.trademe.co.nz/motors/motorbikes/parts-for-sale/electrics/auction-627881348.htm Think something like that'd work?

Haven't tried - will give it a shot. There is a stub there and I'd be able to solder to it but I don't know how long that will last. I'll go looking for a coil. You ever seen the carb? In desperate need of a douse in cleaner isn't it..

I got another one for ya craig haha... And anyone else who wants to chime in - Quick one this time. I'm looking at an old Honda 49cc motorbike engine, not sure what model - it's in a home made go-cart and I don't know where it came from. 1) Ever figured out a solution to this problem? I'm...

Haha yep should have just come straight here. They were stabs at Google. Funny thing too - the first thing I checked 3 weeks ago was the problem lol... Do it once do it right huh. Our lawn mower was doing the same thing, wish the DS carb was as simple as that thing it had the same problem and...

Will leave it with that airbox for now and see how it goes, its running well now anyway more than good enough for the young one. So thanks for your help again! Good to have it alive.

looks like a good idea I didn't consider doing away with the airbox. It is a POS though, pain how that fitting shrinks isn't it, I stopped bothering to fit it over the intake and clamp it, it doesn't stay on anyway and seals good enough with its position lol

The air filter I've got on it now is just a piece of foam I've cut to shape, I left it dry I was worried impregnating it with oil would cause it to fall apart, I would have to order one from a dealer I think and I'm sure it would cost more than its worth over here haha. Is a dry piece of foam...

Yeah I know a smaller one probably suits it better, I don't know if I will bother though. First thing I read in that tutorial there was "A gray ashy or white appearance indicates its running lean". Isn't that pic I posted grey and ashy haha? I will get it nice and clean then take it out for a...

I didn't clean the plug before I took it for that run, suppose that would be a better idea.
