Sorry for confusing matters as I had in my head that there was a positive wire that I needed to make a connection to I will comeback to this point later as I think it is very important but I have some news that I want to share

Not to worry and many thanks for trying. Looks like I am going to have to get the wire cutters out of the tool box tomorrow LOL!!!

Many thanks for the help and look forward to hearing from you. Hopefully I can this done tomorrow and see if it will fire up!!!

Many thanks for the reply. In the box there is a set of instructions which reads as follows: (I hope I have received the right part) The stop switch assembly has 2 wires. 1 with a ring terminal and 1 with no terminal. Connect the spade terminal to the spade terminal on the armature. Select the appropriate wire for the type of stop terminal the engine uses. Cut off the remaining wire and discard. Tape the end of the wire with electrical tape. So what I have done so far is connected the spade to spade on the new coil. I was hoping that I could just connect the the ring wire on the new coil to the body of the machine which mirrors the old one. But I still have to cut the wire that is currently connected to the old coil as I don't think I can disconnect it without trying to give it a good Yank and hoping for the best or remove the flywheel which I am trying to avoid. And as you say I may have to connect this wire to the new coil. I just hope that the other end of the connection is ok.

Finally got my part today as I was told it was out of stock for a while!! Anyway here is a photo of the part and I have removed the old one except for the wire going under the flywheel as I am not sure if I cut this completely off or do I have to attach it the new wire I have been supplied? I presume I just cut it off but I thought I had better check first, Just a quick note to Nigel thanks for the great photos your machine looks fantastic

Thanks again for your guidance I have now ordered the part which should be here next week. Once I have got it I will follow your advice and fit it and hopefully get it running. I will post some photos and report on how I get on later.

Many thanks for the advice I will follow your lead and do the same.Did you have to set up the feeler gauge gap up to the same point? or just do it by eye?

Actually found some time today to try and locate a replacement coil a magnitron variant and after contacting B&S this is what they suugeested The original coil is http://www.briggsandstrattonparts.co.uk/briggs-and-stratton-armature-magneto-298968 and the Magnitron Version they recommend is this http://www.briggsandstrattonparts.co.uk/briggs-and-stratton-armature-magneto-398811 Before I order it Has anyone fitted one of these? and are they difficult to set up? The engine details are Model 170702, Type 5638-01, Code 80082211 Many thanks

I have now removed the air filter assembly and gave the carburettor a bit of a clean up. I think I found the kill wire? (see photos) and it sits under the coil. Presumably I need to remove the coil to access further but I cannot see any breaks in the wire. But I like the idea of the BS Magnetron coil rather than having to remove the flywheel. I am going to check the BS page for testing. as mot sure how this kill switch works. I thought the engine once running was shut down via the fuel valve?

Just a quick update as I managed a quick look at the Hayter yesterday and I couldn't see a kill switch let alone points LOL!! On the handlebar there is only the clutch cable release handle and the govenor speed controller. Which shows choke slow and fast speed setting. I will take another look later today and clean up around the carb and maybe I will see a bit more

Thank you for the information and yes it has an original rubber plug cap I will check the kill switch and the kill wire once I have cleaned it up a bit, but I like the idea of the coil update as it seems to save of hassle in the future. I will update the post once I have had a go at it

Thank you so much for the great advice and help I will certainly be putting it to good use later this week

I have just gotten hold of one of these with a 7HP B&S engine. I was told it was a runner but when I tried starting up found that it had no spark. Someone here mentioned that its normally a spark plug cap thats the culprit and not the the coil pack nut whats the best way to check both?? Can the plug lead be separated from the coil pack?? I have removed and tested the plug and that is ok and I even have a spare new one. I have removed the top cover and so far the only numbers I can find are these AT3600and M275CC The carb as you can see in the photos is pretty manky!! and of course No manuals so any help or advice would be most welcome
