Reiver 14 #1 Posted April 4, 2017 (edited) This is an ED300 charging set, I believe it was built by BSA under licence from Johnson.The previous owner told me that it was from WW2, and had been on a fire launch which was on Belfast Lough. When I got it,there was no compression and no spark.I took the head off to find a stuck exhaust valve, corroded valve seats, and a stuck top compression ring.These are now freed off and valve seats recut and valves ground in. Now have some compression .The points required cleaning and a replacement ht lead restored a healthy blue spark . I am now working my through the dynamo end, it starts off a battery and gives some output.If anybody knows where I can get a choke assy for this engine.Please let me know Edited April 4, 2017 by Reiver 5 Alan, Triumph66, pmackellow and 2 others reacted to this Share this post Link to post Share on other sites
