Tried a couple of hours last weekend tuning the engine.

With stock carb it's a nightmare. It can run very very fast on a very long straight, but it takes forever to rpm up.. Engine is far too rich stationair and middle area. If I lean it, the middle gets much better, but on top it simply dies. If it's tuned for good speed on top, it's very hard to keep it running stationair, and the smoke it produces when you drive away is insane.
I am using "low smoke" fuel !

But great potential !

So next step was the 10E from my friend. Checked it before I put it in... rubber are gone, mixture needle was broken.. Don't know what he did with it but it leaks air through the mixture needle... no option to even try.

Ordered yesterday a brandnew 10E-R, expecting it end of this week.
I thought about the slide, but the rotary just fits in very easily.
My goal is simply good stationair, don't care much about middle, it just shouldn't slow down the car, and a very good top. Everything that is better is just a bonus !
