Hi mate. Also have single carb RSP. Pretty sure the loose breather pipe goes up to the underside of the air filter housing. My carb is also only held on with two diagonally opposite bolts. My 2p, if you’ve already got the head off, you may as well lap the valves, fit new valve stem oil seals etc. My RSP was on 100,000 miles and running Ok, but had the head off as it was smoking on start up, which was the valve stem seals, but lapping valves has fixing it a new lease of life. Good luck 👍🏼
Cheers Sam, on with the valves now so will be interesting to see if that’s the source of lack of compression. Have new mpi valve seals ready. Will post the outcome! Thanks for the comment interesting that ur carb also only has 2 bolts so must be standard.
I’ve had both comments that say 2 studs is as per original and also that it should have 4 so not sure but assume if there are 4 holes there should be 4 studs!
@@MiniJay250 yeah I'm questioning my 4 studs now. Maybe it was a shortcut to make it easier? The manual references 2 but I thought that was because the HS carbs only had 2 holes. Oh well, 2 opposite studs is probably fine!

Rings most likely locked, may free up or a valves stuck open, Leak down test would help you find out.
Slowly working through things…
I haven't watched the rest of the videos so im assuming you figured it out but the carb should definitely have 4 studs and nuts on!
