Was up there the other day. Tried to start it but it wasnt having it. Got the filter off and had a look at the flap. Me Mate recons it was going up and down ok. Got him to push it down a little more and it tried to start straight away.
He said he needed to push it down so none of the flap was touching the outside of the hole if anyone understands stand what i mean.

When we got it started it was idleing like a right cunt. going from 1k up to 1.5k, i cant remember it doing that last time.

Anyone have any likely ideas from where I might have air leaks.

AND where would i find the cold start valve??

All help appreciated lads i want to try everything before shelling out on replacement parts
