Hi!
My car is a MK 9 and runs very good , only with one issue;
when comming on a steep hill the engine fades down untill it stops.
its just like it was loosing the idling speed. When it goes down
its very hard to start it (unless ill reverse a little to a flat
ground). When I finally start it on a steep hill , whole engine bay
feels like gasoline , but this migt be cause im pumping the gas
thoroughly , just to make it start.
Any ideas why this happens - pls post em here

Hello Michael,
I need more info to understand the problem. Are you accelerating
up the hill or watching the idle speed ? Sounds like a float level
problem. Stop pumping the the gas, it does nothing for an SU carb,
there is no accelerator pump.

This problem occurs only when idling.
Pumping the gas a little helps a bit when starting , at least in my
case :)–

Michael,
This sounds like the floats may be sticking, or that the levers
at the top of the floatchambers are binding and not closing the
jets. Have you checked the ends of the overflowpipes when the
enginebay smells like gas? If the floatbowls are assembled
correctly (with the vent washers correct, and the overflow pipes
clear) then a sticking float or Jet will always overflow via the
pipe.

Yes, I’d agree with Andrew, although I’d also offer a punctured
float - take them out & shake them to see if there’s any fuel in
them.–
