Walbro 37 on Adventure A4

[dartvidar]

Hi I have a question about changes out a Walbro WB32 to Walbro WB37 carb on a Solo 210.

My old Walbro WB 32 carb on my Adventure A4, have 3 connections. Fuel inlet from fuel tank, puls port from the motor, and the last connection is conected to the fuel primer pump.

I have just bought a Walbro WB 37 carb, this carb have only 2 connections. One connection for fuel from the fuel tank, and the other is the puls port.

Have anyone done this modification?

How have people done it with the fuel primer pump?

How is it to start if you not use the primer pump.

I hope some one have some tips about this modification.

Thanks

Tom

Hi Tom

My Parajet Volution has a WB37 carb. You prime it by closing the choke and turning the motor over until it just starts to fire. This uses the vacuum pulses of the engine against the diaphragm pump in the carb to pull the petrol up.

You then open the choke and start the engine. Works like a charm.

Hope this helps?

Best regards,

Ian.

Not all WB37 models have the choke.
