S2 fuelling issue
Hi guys. My s2 still wouldn't start due to fuelling issues. Had to hold metering flap down to get it going.
Then I crimped the hose from the oil separator to metering unit while my mate cranked it over and it fired up first time.
So I blocked this off and now vent to atmosphere through a mini k&n filter.
Does this mean I have basically overcome an air leak engine side so now the flap has enough vacuum to pull down and send fuel through???
Starts first time now and runs sweet!!!!

Great thanks, thought as much. However when I said it runs sweet that is a slight porky
It is now slightly overfuelling but I think that is to be expected when changing the breather set up. I am using auto specialists oil separator.
Is it safe to say that with a decent set up now on the fuelling things should be ok?? Engine seems much happier without the vapours going through the metering unit as it is quite heavily modified so does breathe a bit harder.

Im a bit lost, you on a baileys system i guess on the oil separator ? so the bottom pipe to the metering head, you capped of the metering unit and put a K&N on the bottom of the separator ?

What is your set up with the breather pipe now from the oil separator?? Do you have a catch tank ( or similar ) or do you vent straight to atmosphere??
I have merely attached a small breather filter to the end of quite a long samco oil resistant hose and let it vent down near the front anti roll bar.
Seems to be different views on catch tanks etc..and also fumes generated. Mine seems ok at the moment. Cheers

But the part i dont follow is, wont it kill the vacume. ie like when you remove the oil cap it kills the engine ? so by putting a K&N on the baileys tank or whatever make isnt it just like doing that ?? thanks, just intrested
