Dyno shows Air Fuel Ratio rich

[Blu427]

Hi,

Done some checks today ,

Checked both float levels whiche were found to be low no fuel dribble out of bowl screws and so adjusted . I dont think this will cause a rich issue. Checked power valve and found this to be on at no throttle so adjusted .
Fitted in -line fuel pressure gauage and found pressure at 2lbs so not over pressure .
Few more checks tomorrow.

Cheers

You need to go down in jet size.....a lot.

Also, if your fuel pressure is indeed 2psi, you need to raise that up to about 5-6.
