Hiya. Following from the sinking of my boat with it's R3M, I've been working on the magneto (A lucas SR1). I've dried it out overnight in the aga - thanks for the tip Peter, cleaned a huge amount of rubbish out of the case and bearings, re-greased and polished up the points.
All's looking well and it's turning much better, however, there is sparking between the points. I've adjusted them to the 0.3mm as mentioned in the lucas manual and polished up with some wet and dry paper soaked in white spirit. I noticed that the manual recommends meths not white spirit so could this be a problem, or is this a sign that they're too close or that the condenser's had it?
Thanks in advance

The use of Wet & Dry paper leaves a very fine coating of Carborundum, even though you have used spirits with it. Peter is right to a point to suspect the Condenser. You used to be able to buy special "Points" files but I now just use my wifes Diamond coated Nail File or a diamond honing plate, as used for woodworking tools. These leave no residue but, wipe the points faces with a clean rag as well, just to be sure.
You will most always get a very minute spark on the points at low revolutions, this is normal.
Hope this helps,

My P55 engine won't start. It has been good and reliable after a full overhaul at Fairways last year but I had to leave the boat for a few weeks and there was a lot of rain, so I guess that the magneto (Lucas SR2) may have got damp. The engine tunrs easily non the crank handle, but there is no sign of life, although on the first crasnking it did fire for a few seconds but then stopped. Is this likely to be a magneto problem? How should I solve it? I have the magneto off at present.

Check the resistance on both sides of the coil first with a multi-meter. If infinity i.e. no continuity one either side the coil is gone. They usually go on the high side. If so you will need a new coil. Sometimes you can repair them if it's corrosion related to high output tab.
If the coil is OK then change the condenser. From memory a Bosch 209 will fit you just have to elongate the mounting hole and trim the tab on it it doesn't fowl. Clean the points as well.
