Newlister here. Had my CS going today, Could not wait just had to try it. made some water pipes up, put together as they would fit. had a little 12 volt water pump. And a little small heater matrix out of a Vauxhall Corsa I think, needed to try matrix to see if it warmed thru. Only second time I tried to fire it up. Ist when I went to see it, 2nd nearly start, and third time, very easy. needed to turn it a little more, and put it on high compression. well it shook the van but not as much as I expected. And the exhaust noise was not as loud as I thought it was going to be. maybe when it has a good load it will need a silencer. Anyway just had to see it going. after a while. it started to puff traces of oily smoke from the exhaust. it was worse screwing the knob out. Compression seems really good thou. Piston /bore trouble.? valve guides?. took the side plate off to see inside and oil had been splashing about. The oil in the sump looks new to see on my fingers. but the oil in exhaust is dirty black, like it's not had an oil change for a long time. There is compression leaking out, just a little bit of pressure from the small top and bottom holes in the compression knob boss.? and this gets really very warm/hot. Also there is a middle bit where the compression seems to go when turning the knob out carry on and the comp comes back when the knob is out. Not seen one running before close up so. I don't think this can be normal.? Did see a piece about the flapper/reed valve. could this be stuck ? Well if anyone is interested. have added some more pictures. and a few more soon. cheers Newlister
