Hello everyone,
I have what I believe to be an old 20-30 hp johnson, I got the motor with a boat I bought and am restoring, well infact the boats all done. I'm a marine engineer in the Merchant navy and have just come back from sea and with my time off I thought i'de try to restore this old motor it looks old but it also looks solid and the compression is great. However there is no spark! I am planning on removing the flywheel in the next couple of days and mabie taking the whole thing to bits, let loose with some tools and get it looking decent and running. I am having trouble finding out the model of the motor the model ID plate has being painted over and when I removed the paint there was nothing left the only thing thats left is the number on the core in the middle (see photos) I have read through the forum and it has helped alot. Although I am a marine engineer these engines are completely new to me and although obviously I have a good idea what im doing but every engine is different and I am hoping with the experience on here someone can tell me what model it is so I can try my best to source some parts. Any tips would be much appreciated. Plus I believe this oldi has points witch im not too sure about how to check and replace those as I believe they are responsible for my lack of a spark.
Any help no matter how small would be much appreciated.
Many Thanks
John
