Hi there.

Fuel not getting through to the engine on my SR43A

Took the carbs off and found a pipe was disconnected but can't seem to see where it should go.

There is a t piece in between the carbs at the top on the airbox side.

Shown on this schematic as part number 50 :

Anyhelp appreciated!

Many Thanks

David

This pipe coming from that T-piece is about 15-20 cm long and goes nowhere.. It is called "air vent hose" in the work shop manual and what it does is to let the carbs breath out the fuel gas...
Your problem must be somewhere else..

Indeed. I`ve even removed that length of pipe on all my Bigs as it serves no purpose at all.
Check your vacuum line is not perished or disconnected or there`s not a kink in a fuel line. Fuel filters can also become clogged over time.
