Hi all.

I've been working on my mini for a while after it sitting for 6 years with a blown head gasket. I've got it 'running'. With the choke out, it runs ok but when it's up to temp and I take the choke off, it drops revs a lot, then picks up a bit then drops off again.
My thoughts was to increase the idle but it just surges higher then almost stalls and repeats this. I then thought maybe it's too lean, increasing revs but almost stalling due to fuel starvation? I've adjusted it slightly but don't want to carry on as I may make things worse if I follow my untrained intuition. Perhaps it's too rich and flooding? I just don't know.

Any help would be great.

It's a 998 with a HS4 carb.

How old is the fuel in it ?

The other thing is there's every chance the fuel system has dried gunnmy residue through it and will likely need a clean out.

It's new fuel. I suppose there is a possibility that there was some old fuel in the lines but as stated, it seems to run ok with the choke out. Just not when it's at temp and choke off.
I have a glass fuel filter and the fuel seems to be clean coming in, no bits in the filter, no odd color. The float has been cleaned also.
