No, not flooding, that was what I thought was wrong at the very beginning.

Changed everything. except crank and seals, which I'm in the middle of doing now.

[Wack]

Don't forget to pressure test after

I wonder if others think like myself?

Are there any assumptions being made with regard to the three necessary requirements?
Fuel, ignition, compression.

Fresh fuel, different carbs, fuel tap and breather.
No fuel filters fitted?
Worth a shot of Bradex Easy Start.

Ignition? Plug gapped; with correct feelers, plug cap, HT lead, swapped CDI and stator and flywheel. Woodruff key intact.
Have you measured frame earth to engine earth... Should be 0 ohms.
Consider isolating all junction and terminal boxes and connecting wiring straight through in case anything leaking to earth.

Compression: Different top end tried so gaskets new and no leaks.
You say the oil seals are OK but how have you established their integrity?
Aside from a crack taking in air in the bottom of the crankcase I would say one or more of the replaced/substituted components is faulty.

Trust me, I'm not criticising but I think there is something very basic missing here when you examine ....Fuel, Ignition, Compression. I wish I lived nearby !

Bilko is the kickstart shaft broken?

[Scooterlam]

I know you're not critisizing. I think there's something basic missing Chris, but I'm buggered if I knoqw what it is!!!

You could be onto something...

I placed a few copies of Jet Set and lit an incense stick on it.

Try a Feng Shui master in your garage, see if the improved harmony encourage the spirits to give it power...

The zen part of the book was a bit over my head, but the bits relating to the thought processes required to problem solve
Were quite enlightening.
its a big old book but well worth a read.
Recomended by users of the old forum.

[sunrisemac]

spark plug's fallen out that's the problem.....

[Bilko]

Mag housing off. partly grubby inside face, but nothing else. Crank out later.

not all of them

[Bilko]

Have you checked the crank for alignment?

Took the crank out and the conrod has a good bit of play

[CHRIS in MARGATE]

Sideways or up and down. There is play normally sideways; just depends how much.

[Bilko]

Up and down seems fine, but sideways does seem excessive and when I do the thump on the conrod with the palm ala Sticky's Manual, I do get a metal sound rather then a dull thud.

[Bilko]

Does this help any?

[CHRIS in MARGATE]

Looks normal to me.
