cb200 in a buggy

[Barfly]

Hello all
I found a buggy at the rubbish dump that has been based on one of the Taipan buggies you see in magazines.
I cant get it to run.
I have a wiring diagram from here (http://www.dunworth.clara.net/wire_dig.html)
I have great spark to the points, but when I earth the plugs there is no spark to them, if I put the plugs in the leads and then hold an earth wire about 1mm away I get a really good spark. It has me baffled, as soon as I screw the plugs into the head and earth them I get nothing at all.
Someone has spent a lot of time on this thing, hyd disk brakes, hyd clutch.
My kids a dying to get into this.
Any help appreciated.

try useing brand new plugs.
Ive got three different coils,"tried all three" new condensor, new plugs and cleaned and adjusted the points. Its still the same. :confused:

make sure the engine is grounded.

Yeah did that one, I took the connections off and cleaned them but its still the same.
This is driving me nuts.

Something else I just noticed, when I connect the power lead to the battery with the points closed there is a small arc where I am making the connection, but when the points are open this dosent happen. Is this normal?

something is wired wrong. i'm pretty sure you shouldn't have a spark between the points until you turn the engine over. it might be the stator (under your flywheel) might be burnt. its not creating a energy to create a spark so its using the battery. my dt125 had that problem. if you have a manual it would tell you the ohmes that should be there. i would check that.

might be easier to just put a different engine in it. something that runs.

Your probably right but Im 500 miles from the nearest city so getting one is a problem.

I just reread this, the spark isnt between the points its where I make the connection from the battery to the power lead, Ive been told its normal.
I got a second hand coil from a bike wreckers yeasterday, it had been tested as okay. I put the coil in and the motor ran for a couple of seconds and stopped once again. Now Im back to square one again.
