Whilst I appreciate a PH2 is not a "classic" stationary engine I think this is the group that can give me the answer.
Assuming a PH2 hasn't a two piece camshaft and its assembled wrongly - can anyone explain why the engine over 2 turns has both pistons on their compression stoke (180 deg apart) on one turn and obviously then a turn with no compression? I think that's explained it but trying another way - turning the crankshaft through 720 degs the results in:
0 compression started 90compression "lost" 180 compression started 270 compression "lost" 720 - back to 0I hope this is not egg on face time but it just offends me.
Thanks
