Laying up the car ready for winter |

Doubt if I will get many runs out in the car until next spring, so wondering what most do to
get the car ready for laying up over winter. Already had a few high winds with the usual salt
spray, and know the councils around here do like to treat the roads in liberal amounts of salt.
Presently looking at doing oil changes on engine, gearbox, and rear axle.
Do I leave water/antifreeze in, or drain the system.
Body and underside have been cleaned, so not sure if worth giving it another coat of
'Lanoguard' or similar.
Going to jack the car up and put it on axle stands, so tyres will not end up with flat spots.
Leaving the hood and side screens up to keep the inside fairly clean.
Battery is on a conditioner so 'should' be ok over winter, but always worth checking.
Got a fairly good car cover, but during the winter gales we get a lot of salt spray (enough to
coat house windows so you cannot see through them), so wondering if there is a better protective
solution.
Was wiondering if worth putting a small heater under the cover, but obviously a fire risk.
Garage unfortunately is not heated and even with all doors closed can be a bit draughty.
Any other suggestions ?.
Martin.

Magneto threads |

A little while ago, I obtained a Mag engine and gearbox that had been used in a sea going boat. The engine was complete with magneto and dynamo, but was seized solid. Apparently it had been cooled by sea water! I assumed it was an engine that had been removed from a car and adapted for boat use. Everything on the engine had been painted green, which I thought odd. It transpires that Austin 7 marine engines were painted green by the factory.
Anyway, the cylinder block, head and pistons where beyond salvaging, but the conrods, crank and front gears are exceptionally good.
On the Magneto, there is an automatic ignition advance mechanism, the like of which I have never seen before. The mag is A Lucas Model SR4 type Mk IIA 10 57 Lucas number 42290D. I assume the original Magneto was replaced around 1957.
I started stripping the Mag, and found a slotted screw central to the main nut securing the mag' drive gear. Whist attempting to remove the said screw, it snapped off at the head. Having continued and got the drive gear and advance mechanism of the front of the mag, I then removed the rotor with the view of drilling out the broken screw. Centre popped the shaft, and started to drill out the remains of the broken screw. To my surprise the broken screw screwed itself out!. It turns out to be a left hand thread of 3/16th BSF.
After this long winded introduction, does anyone know where I can obtain a replacement L/H thread 3/16 BSF Screw?
Another oddity I noticed, The dynamo has a toothed cog sticking out of it's end, a form of REV Counter Drive perhaps?
I do not know how to load a picture of the ignition advance mechanism on to this page
