Running rich

[Fused7]

Hi chaps
The 5 seems to be running rich a few people have commented on the petrol smell after start up, also it seems to idle really low (under 1k rpm) how do I adjust these?
Thanks

Do you know what size jets are in yor carb?

The idle screw is place to start for idle, but they are supposed to idle under 1k rpm' I always aim for around 850-900rpm idle keeping the afr's around 14.7


+ to add it's an R5 GTT with a carb they always smell of fuel:laugh:

I'd check it's not actually leaking fuel also. Check all metal and rubber piping from the tank to the engine.
