markha,

1st thing I have to say is get yourself a note pad and write everything down. I created a document which I used to tune my Webers. If you are not using a note pad I hope you have an excellant memory.

2nd, You are going to receive different opinion here, I am sure all of them are good and valid. However, get the thought out of your mind that what 1 person is running in the same motor will work for you. All the advice you receive will put you tuning in the ball park.

Dont worry too much about the mixture setting being 3/4 1 turn 1 1/2 turn. Get to know your motor.

Study how the emulsion tube works, get a good understanding of this.

Chuck @ Inglese is a great guy but the values he is telling you is to get you started. Not a perfect tune.

As Rick mentioned, you can stay with the F16 and tune around it or you can try and see what the motor is asking for at different stages idle, transition, main.

I would forget about the main stack right now and concentrate on the idle circuit. Get this right. I think once you see how the emlsion tube operates you will see that it makes a huge difference with normal driviablility.

Let start off with this:

List all the jets you have so we know what we can test to see if we are heading in the right direction.

As for idle, I think you will find that the 60 idle fuel jet will be the 1 one you will need, as suggested by Rick. You can then get creative with the holder and etube to maintain your 13.5 ratio.

Just to give you an idea I am running 15.5 @ idle (standing still) and 13 .2 off idle. My idle circuit is 60 fuel and 70 holder with 40 chokes on a BB.

When jumping from 60 holder to 65 and then 70, these were huges changes.

Good luck
