raynerd:
Thanks for all the info regarding the piston o-ring. I`ll let you know how I get on.
dbvandy - I`m really not sure what I`m doing about ignition yet. A lot of it falls down to cost, what you showed me seems an excellent price. I`d quite like to use my smaller 10mm spark plug so I`m not sure if it`ll fit in place of the 14mm plug that comes with it. I`ve finally got my head around the points/contacts system that the original plans suggest but they look clunky and I believe I could do without them if I used the item you linked to?
Where or what is the hall sensor in this bundle and how will it be fitted?
I believe this is the sort of thing:

...but it worked out about £90+ when I priced it up. Is it the same sort of thing in the link that you have suggested?

So what actually spins and triggers the hall sensor? I appreciate your advice, this is all new to me!

Chris,
If you are looking to keep the price down, you can actually make your own.
I used to make the TIM 6 units, for less that around a fiver each.
It isn't the switchgear part that is the expensive bit, it is the coil. That is why these modules are rather expensive, they have it all built in.
If you can hide a car or motorcycle coil somewhere, then the TIM 6 version on here will be fine.

Basically, you embed a small neo magnet in the flywheel or camshaft end, and as it passes the close mounted hall sensor, the sensor sends a signal to circuit which then fires the coil, et voila, spark at the plug (any size).
On the TIM 6 shown, it doesn't need to be a hall sensor, it could be contact breakers or even a microswitch.
