Hello!

What carburettor do you recommend for a Quattrini M1XL cylinder kit? The cylinder kit comes with a manifold that has a 30mm inner and 40mm outer diameter.

Interested to know too... I'm trying to track down a PX150 cases for a project

That's the intake manifold which the cylinder kit comes with....

Sorry, maybe I wasnt clear, I meant, i'm trying to track down a PX150 crankcase for a (planned not brought yet) Quattrini M1XL kit.

So I'd be interested to know what carb people would suggest too...

A flatslide dellorto would be tempting for me... but dont know if its a good combo.

My suggestion is to do some searching on Google, if you haven't already, and find a few setups including exhaust you can emulate. This could save you a lot of headaches and time. Someone here should chime in, I know there is a site with jetting and setups listed I just can't remember it at the moment.

They are on the expensive side, but you could try a smart carburetor, a few people here have tried them and like them.

You might try calling this shop and asking if they have a baseline using a smart carb.

Is it this site?

It's pretty cool to check out and reference, but realised a lot of the setups didn't work for me...

Yes, it had some TMX setups I looked at.

I think TMX 32 and 35 comes with a 40mm connection so fits the manifold.
