That's a mistake most people make. When they richen the LSN and when the idle drops, they turn up the idle screw to open big to keep the engine running !

Did you try the pinch method after Michael had tuned your engine - I always tune my bottom end, so that the engine revs still rise a bit before cutting out when using the pinch method - what was yours like?

FYI, Mr Kris engine+clutch before main is set by Massimo and this is the condition :
- modified flyweight
- 1.8 centax spring (Centax2)
- yelow clutch shoe
- 61/17 1st gear
and the centax nut measurement is 1.00 mm
On the main I did not change anything but adding up idle rpm.
And the engine run healthly after the main, final temp is 106 C (EXERGEN on the back of lowest heatsink)

Ah ! Worse case scenario, just let those guys tune your engine when you chance upon them. Pretty effortless for them and you can just concentrate on your driving.
I guess you probably only need to tune plus minus 5 minute turns on the needles to get the right setting. That's all.

But I thought I noticed that Fabio was pulling slightly away from Massimo on the straights in the first few minutes...

1st time hit the track Massimo trying to leap the sweeper half throttle just like 1/8 and Fabio is more wiser to take it slowly.
Thats why the speed they enter sweeper is different.
From what I see both of their car is underteering badly, it is not their maximal setup.

True. They all set it that way. When the engine is cold, it's so difficult to start. The engine will be difficult to idle and will sound blubbery after a 5 to 10 seconds ilding. I think that's why they put one of their hands on the heatsink to gauge if there is enough heat before they start revving and tuning the engine.
But the magic thing is when the engine and car comes in after a few laps... That's where you see the engine purring perfectly without skipping a beat.

the track is not that big ..1 long straight ... not that long ..most of the time ..need to use a lot of Low end when you come out from corner.. you need low end a big rich, otherwise the engine can be overheat ..
For biger track .....fast turn, you will have to tune the highend rich and low end a little lean(just nice) ..So your engine will not be over heat ...coz most of the time u use high end/high speed..so give more fuel.

They are not really that fast.. they only joking around, even on the driver stand at the A main. Fabio is more clean, Massimo is bit nasty but both was damn consistent.
Suruth car is the best handling among of them and he is driving just like Surikarn.... very clean.
Pyramid notes when he practicing, he can take the chicane as a direct straight line for 6-7 laps. That is something

I try 1 long understeer and 2 long the car start to oversteering in mid corner. But I enjoying driving 1/8 on that track. And somehow makes my braking ability get better while driving 1/10 with 1 way.

It's weird actually... Available traction kind fluctuate in the duration of the whole weekend. When traction was high during practice before the rain, I thought 37 front and rear was a little twitchy for me to drive. So I had 40 fronts and 37 rears which drove OK and even had 42 front and 40 rears at some point.
In the end, it was a gamble as I took the risk of using 37 all around without having to test what tires were good for that Sunday morning. I told my venerable wingman <cough, cough> to prepare for front tire change to 40 front in that 3 minute given warm up time in the event the 37 fronts did not work out. But all came out well and good.
