1977 400F2 first restore project
robvangulik:
Maybe it has been stuck once and been slotted to turn/wriggle it out? So long as the mating surface below hasn't been damaged it should be allright. ;)

Carbs back on today and she started up fine with no leaks from them. Engine ran well with all 4 exhaust headers getting hot at a similar rate. Quite a lot of smoke from the exhaust. Just a few little jobs to do before she is ready for another test ride and to check compression's when hot. Then I can get stuck in taking her to bits!
Nurse Julie:
Great work. I find that carbs always appreciate a new set of O rings 😁😁😁

Finally a dry day and an opportunity for a test ride. No2 header staying cold. Traced to a faulty spark plug, swapped for a new one and good to go. Just a short ride up to 50 mph and kept revs below 5000. Engine pulled fine. Nothing fell off including me. Front brake improved since I fitted new pads. Checked compression's when hot only to find them slightly lower than when tested cold, they were all around the 90 mark. Previously I refitted the carbs with the air box on and managed to join the club of those that have blackened a finger end so I now have the trophy. I've started the strip down now this marks the real start of the project. I plan to strip the top end with the engine in the frame. 2 tappet covers are stuck so I've sprayed them with plus gas to see if they will play ball tomorrow. 4 of the nuts on the header are the square cheapo coach bolt type however they came off easy enough with a 12 mm ring spanner.
Bryanj:
If it runs fine and ticks over OK i would suspect the gauge
