Rate my spark plugs...

Postby Technohedge » Sun Sep 09, 2018 5:32 pm

From Caldina GTT thats not been boosting like it should for a while now. Keep meaning to get to the bottom of it.

Pressure gauge reads normal boost pressure, but it smells a lot of unburnt fuel so im wondering if its rich?

seems a fair bit of carbon on the plugs?


Left plug is from cylinder nearest river
