The 600 is supplied with two jet combo's from the factory, I guess the first thing is knowing what jets and rods are fitted now. I think that the richer setup used 100 primaries 70-47 rods and 95 secondaries.

I tried very hard to get a 600 carb to work on my 4.6 lump (280 ci), I could get the AFR figures quite good but the engine would virtually stall under braking with a rich bog. A 5 degree wedge plate helped but not much. (The float heights were correct!)

You could try 73-47 rods, as a start, this is 8% leaner on cruise than the base setup but really you will not get very far without some means of analizing the exhaust gas in my humble!

If you slap the carb on I'm sure that the engine will run but you don't want it running to rich on cruise because you'll wash the bores, obviously all the other carb circuits are important too!

I'm pleased for you that it fired up and that you have noticed an improvement but don't let fool you into thinking that the AFR will be correct for all of the carbs circuits. (They 'might' be, but they might not be!)
