Got head on. New gaskets all round,new studs,nuts and washers everywhere and gave everything a real good clean. Tried it by hand and all seemed ok.Turned it over a few times and it started. Runs fine, slight misfire but id expect that as timing hasnt been tuned yet.Top end very tappety but the more i run it the quiter it gets.Cant run it for long at the mo as got a new fan switch and havent got a big enuf spanner to put it on so no water in there at the mo. Hopefully sort 2moz or monday latest, then off to Janos in next few weeks for tuneup and pick up my new doors in Essex too.
