Roybi RSV 3100E leaf blower.

Hi Lads. looking at a hand held RSV 3100E which was given to me. The fuel lines and primer were present but not fitted as they had gone brittle. I bought a new bulb- primer and pipes, all fitted BUT I can't see which of the two pipes fits which connection on the carb. I have found a few parts 

list but they don't show the connections. The connections on the bulb and different lengths which indicated the flow. HELP please.

I have connected the pipes and primed the system. Petrol is flooding straight into the engine. It is a Walbro Carb. Would it be a diaphragm ?

Possibly. Maybe sticking needle valve holding the carb float down? Is the carb flooding? Are you sure you have the fuel pipes the right way?

It's pouring into the combustion chamber at quite a rate. I will get a rebuild kit, they are cheap. Would having the pipes in wrong order let this happen, Thanks.

Don't know for sure. I've never had I happen. Just a thought. You could try swapping them round.
