Default 40cc crankcase smoke system

Hi Guys
I'm sure this question has been posted somewhere on RCU before but there are so many threats it's getting difficult to find the answer. A couple of guys at my local club have installed a smoke system utilising pressure from the crankcase. They have a D.A 50 and a D.L 50 (rear mount carby) and they basically tapped a nipple into the reed block to provide the pressure. A tube then runs from the nipple on the reed block, through a one way pressure regulating valve and into a dedicated smoke tank. They have fitted a servo operated switch between the tank and exhaust to turn the smoke on and off remotely. The system is very effective and provides a good thick smoke for around 40 seconds. They are using a 50 / 50 mix of diesel and brake fluid. My question is, on a side mount carby, such as a BCME 40, where do I tap a nipple to get the same result?. Do I tap it into the actual crankcase, and where abouts should it be tapped.
The system they used seems cheap, reliable and VERY effective - and adds very little weight. No additional batteries or pumps. If anybody has done this can you please let me know and maybe post a pic.
Thanks
