Anybody no what jetting I should be using

I'd start here, remember all jettings a guide, even machines with the same setup will require different jetting much of the time.

I run a muggy 186, JL3, 30mm PHBH transfers matched, 16 x 46 LI 150 box in it. no problems with it screeming, like has been said above check the clutch.

Leaving gearbox as it is , have removed the AF lightend flywheel an I'm putting a standard one on I'm also resetting the timing to 14 degrees plus I've sent my 30mil delly off to cam lam to have it blue printed so to speak to suit my setup hopefully all will be well with it once I get all this done
