help please - Aprilia Pegaso 650 carb

[Just Anne]

We (well Ian mostly) is suffering severe wallet pains as a result of my boy's disagreable Pegaso 650. Cutting a very long story short, the carb isn't pulling fuel through. We sent it to a carb man who said idle screw was broken and a few other bits were apparently worn out and he refurbed it for £155. When it came back after successful bench testing our tame mechanic said it still wouldn't run. He's talking to the carb man and we're awaiting the outcome but it's all been such a pain, we don't hold out much hope. Any ideas would be gratefully received. Thanks.

will the engine tick over but not rev with this carb fitted?

[Just Anne]

no, apparently it's not pulling fuel through at all at the mo. What you described was the original problem, in that it wouldn't run without the choke on. Any ideas?

Maybe the problem is further up like kinked fuel line or problem at fuel pump or fuel tank vent blocked.
Just things to check out if you already haven't.

have you checked compression or leaky exhaust valve? its hard to diagnose without actually getting me hands dirty. i would do a compression check.
