V35II - Hydraulic Lock...

   My last Monza became something of a ball ache but like your bike it suffered random flooding, especially the left side. I never managed to pin the problem down as the carb had been fully refurbished, so I replaced it with another one after throwing the original across the garage in frustration My flooding was of a similar nature to yours but I thought it wise to remove the head and barrel rather than leave it to soak in oil for a week. By doing that I was able to confirm that no damage had been caused but I did find that the piston rings and bores were `dry` (very little oil residue etc.). On reassembly I not only lubricated the bore and piston but also dripped oil onto the crankshaft and big ends for good measure. Obviously I changed the engine oil and then ran it for 50 miles before I changed it again just to be on the safe side.
My advantage over you was that I had no other projects on the go at the time

	Thanks Paul, I've put some 5W oil in & will let it soak a while.. The float valves & needles were new on both carbs quite recently as a "while I'm at it" measure, maybe I'll try and find the old ones...... Cheers, Adrian Bristol UK

	Thanks Chris, To be fair the bike had not been any trouble recently (famous last words!) so I guess I can't really complain, it is over 40 years old after all... You are quite correct about other things on the go. Ignoring the V50III project there's the MSS with the self-adjusting clutch (working on that) & the Venom that starts when IT feels like it which now has a leaking fuel tap as well..... At least I have the BSA if I actually want to ride somewhere........... !! Ahh well...... I'll drop the oil tomorrow on the Guzzi and see what that looks like.... Cheers, Adrian Bristol UK
