You have a lot of cylinder pressure there, but not too much. You have no quench, but that should not be an issue. You ned to add fuel, as you suspect. You should get the Pro Max metering plates that will use standard jets to adjust the outboard mixtures. I seem to recall that Euro 98 is about the same as our 93. So it's not octane. i think you're lean as you think. So instead of rebuilding the engine, give it the fuel it wants. You should NOT be running that engine until you figure it out. KBs and pinging are NOT GOOD at all. Also, you should be able to go to the purple springs in your outboard vacuum pods after you get some jet in it. What is you timing curve? You should be around 15° initial, and total around 36° with it all in somewhere around 3K.




Dave , I have seen KB spec a max of 34* total ???

Edit I just reread your first post , I'm with moper it sounds like you are too lean .
