Carb not pulling fuel

[Ollie]

I’ve been running my wt997 for a good 8 months now and nearly 10 litres of fuel, it recently started cutting out after prolonged full throttle so I stripped the carb and found that the mesh screen on the pump side was blocked (caused by my clunk falling apart) so I gave it a clean and out the pump side back together correctly. Though I would check the metering valve height so I checked that and it was bang on. Put it back on the car today plumbed it up and now the primer bulb will only pull a dribble of fuel into the bulb? Any ideas?

Probably trash in it somewhere. Me personally there cheap enough I would replace it.

you could have put the fuel lines on the wrong way round ollie,
clunk or black line goes to the bottom of the carb and the clear or yellow return goes to the top of the carb,
or yer diaphram could be stretched or torn in the carb,

i figured it out, the in line fuel filter i have was leaking so every time i depressed the rpimer bulb it was drawing in air rather than fuel

Take that inline filter and throw it in the trash.

That clunk will do a better job at keeping the lines clean than that inline and having 2 is very redundant and not necessary.

The clunk fell apart so I only put it in temporarily, got a new clunk on the way
