Default RE: any one seen this before??

The mjority of the poblm of multi-cylined sharing one crank volume is more of getting the fuel-air charger into the crank case volume so that it is ready to be thown into th cylinder. Ignition is one of the problems, but the induction problem will represent the majority of the problem here. So, spark ignition will not resolve the induction problem.

For the fuel-air charge to be sufficiently enough and presuriezed to be put into multi cylinders that share that volume, the best type of engine would be valved 4-stroke or the valved 2-stoke draw-through scavanging engines. Four stroke would be best since the individual cylinders do all of the pumping work and there is no reliance on the crankcase volume to do any pumping work at all.

aww, i see. it does make all the sense... at least the bomb-problem would be solved with a sparky.

LOL

I agree. For our loop-scavanging 2-stroke model engines to go multi-cylinder and fit into a monster truck, an in-line design with each cylinder with its own crank case volume is the way to go. forget V with more than one cylinder on the same crank volume.
