Saving Old Seagulls

been on before with ongoing ignition problem with my fortyplus with clutch,
while i wait to take delivery of a electrical tester i have been having a good clean of the engine.
i noticed that my magneto has an recessed line going around the outside the full diameter of the magneto about 10mm up from the bottom edge.
i looked on the site at as many pictures of fortyplus engines as i could find and did not find one with the same indent ,could this be relevant to the ignition problems i,m having.
thanks, frank. leeds, west yorks.

My FPC circa 1978 has the same feature

When I got it I checked for a spark and got a supurb jolt. Made my hair stand on end somewhat

Without your full engine no one else know which engine type your asking questions about, hence the lack of answers!

2 days ago he said it was fpc 1283ee8

for unknown reasons he has started a new thread instead of continuing with the previous one!

appologises to everyone ,i,ve only just started to use the forum so havent got to grips with how it works fully,would have continued with the previous thread if i,d known,will do so in future.
hope i can get my engine sparking like the guy who says his makes his hair stand on end,
just got my digital multitester of the postman this morning so am eager to get my problem solving head on and find out why no spark.
thanks again .

oyster 49 ,your engine looks identical to mine ,manufacture date for mine is may 78.
hope i can get mine to spark like yours.
thanks for the reply ,new to the forum so just getting to know how to use it but seems a great way for a novice like me to learn.
