Hi All, NOEB with a problem already!!

Hello all, my wife and I have just bought a VTX each, a 2006 R and a 2007 C.

Unfortunately we are already in trouble and need of some guidance. The R ran out of gas. Thinking it should be nothing more than fill her up and off we go, not that easy for some reason. Just would not start. Got her home and checked the plugs after attempting to start and they are dry. Looked at the carb to see if any gas was being pumped out when rotating the throttle and nothing coming out of the accel pump.
So I took the output hose off the tank pep cock, opened it and expected to see gas running out but nothing. I assumed the pep cock was blocked, may be with crud from the gas running out.
Blowing down through the inlet pipe I guessed by the amount of pressure I needed to use the spring loaded diaphragm needs to be overcome before gas will come out of the outlet. What is the purpose of the diaphragm as it is vented to atmosphere? I don't believe there is a gas pump between the tank and the carb?

If any one can offer some next steps it would be appreciated. Looks like the carb may need to come off and be cleaned?
Apologies for so many questions for my first post but we are both new riders and want to get out whilst the Michigan summer holds up!!

Cheers, John

Make sure the vacuum line is hooked up to the forward side of the valve.

The diaphragm is for the vacuum safety feature of the VTX. The vacuum line from the carb, once the engine is turning over, pulls the diaphragm to open the petcock for fuel flow. These are really a pain in the arse...imho. I removed mine after several mmmm hassles. So you hook it all back together and make sure vacuum lines are hooked up, leave the gas line off, turn petcock on, turn the engine as to start and see if fuel runs out.......fuel in tank of course. If yes then hook up fuel line and ride. If not, I would look the vacuum hose over real well, check diaphragm to make sure no holes in it........
The carb may need cleaned but lets get fuel first...

My 071300 r stopped running one day. After applying a vacume to the petcock , no gas flowed.igot a diaphram kit for petcock off eBay and that fixed it. Kit # 16953-kea-023 Honda part number. When I took it apart diaphram piston was stuck. Be sure you got a filter on that petcock tube.eo
