I'm very glad I got your attention. I'm surprised no one else mentioned it. If you search the forum you will find everything you ever wanted to know about the dreaded sludge trap. Basically BSA designed a centrifugal filter system in the oilway that passes through the crankshaft. If you do not know for sure that the sludge trap has  been cleaned then, sorry but it means a complete strip so you can remove two blanking plugs on the webs. You just do not want that gunk blocking oil flow or coming out!!!

...and it will be some crusty crud.

Harvey, pay attention seems we got lots of catching up and learning to do

Since we're talking about obscure internals that are not well covered by the Haynes Manual (for example), while you are inside of the crankcase you are going to want to replace the oil retaining ball and oil retaining ball spring (01-4675 and 67-1400, respectively). When doing this you should re-seat the ball by your method of choice. Mine was to use a sacrificial ball glued to the end of piece of aluminum tubing and used with grinding paste similar to valve lapping. Others prefer a sharp rap on the ball with a drift. This will help to reduce wet-sumping caused by oil seeping past the pump then past this check-ball. Here is a link to an embarrassing video I made showing removal of the ball:

it would appear that way dave, i am just waiting for the homework to appear! 

next problem is i had a spark, or two actually 180 deg apart last week but this week the magneto appears to have run out of sparks, can i get it refilled at Halfords or am i better off looking for a main dealer

waiting in anticipation for an answer

Have you ascertained (phew) that it is the Maggie that has run out of sparks and not the plugs ability to pass them on

[muskrat]

G'day Derek.
Homework has arrived. Use of the search is recommended. Most problems have already been spoken of. Feel free to reopen old topics if they are relative to your query.
Posting of specific problems/questions in the relative sections is a must.
You may need some Lucas replacements.
Cheers

no plugs involved just bare leads, new ones i might add with new pick up thingummyjigs!

wiring harness smoke! that made me laugh 

i wonder if that TL1000 is still for sale?

Trying to think of obscure causes of sudden loss of spark:

• Check to be sure that the kill brush and wire are insulated from ground when the kill button is not being pushed.
• Check to be sure the points spring is not touching the cam.
• Look at the slip ring through the top pickup hole to be sure it (the slip ring) is clean and not damaged.
• Check to be sure the springs on your pick-up bushes are fully seated at the bottoms of the holders.

Then, of course, there are the more typical stuff having to do with points. Not bringing up condenser yet because you said you had spark that mysteriously disappeared.
