My 650 CSR project

I would think you can get the brass port back in to the carb either as Tex indicates or use some fuel proof RTV or the like. Wanted to say the stock petcocks for the H models are all vacuum operated and have 2 ports on them. One for the fuel to get to the carbs, and one to provide vacuum to the petcock to allow fuel to flow. I have added a pic of a set of vm24 carbs with an accel pump and a vacuum port on #2.
 
 

Great picture, thanks! Helps me understand what I have here.

That is a fairly common problem. Last time it happened to me, I knurled up the brass tube with a pair of pliers and carefully pressed it back into the petcock. Worked a treat.

I've knurled it just by trying to get it out of the hose to which it has bonded. I think I will use a bit of Seal All on it when I put it back in.

In other project news, I made my way under the cam covers and checked clearances. Everything checked out within spec, but being my first time on this engine I am going to check them again tomorrow to make sure I did it right.

Moving forward if hoses are "really tight" you are better off splitting them with a sharp knife and then trimming back the end of the hose before re-fitting

I was being slightly sarcastic, which you have to watch out for with me. I did start to scratch it up a little when I first tried to pull it out so I stopped and cut it out.

FSM specs call for .08 to .18 clearance

Following the FSM 4-step directions my valve #s this morning are, from I1 to E4

Intake
.10
.10
.10
.10
Exhaust
.18 (tight so maybe .17?)
.18  (same ""   "")
.15
.15

I will double check these but they seem good to go. A more experienced person might want more clearance on the intake but I am not that person, yet. I'd hate to cause trouble for myself when .10 is "good enuff"
