R100, used locally in town for MOT early April, standing till 7th May, no problem starting up and 60/70 mile run out, pulling like a train.
Return home, fuel off coming down the lane as usual, back in to the garage and on its side stand with a block of wood underneath the stand to hold it just a fraction off level, as usual.
Pull it out this afternoon for a run around in the sunshine and start it up. Fires up ok but with a slight misfire on right hand cylinder........
Then suddenly thick, very thick grey smoke from the the right silencer and a small amount from the left, more even thicker smoke from the front cross over tube on the exhaust. Slowly cleared and the engine ran sweetly. Went out for a spin and alls fine, poping and banging from the right cylinder on small throttle openings in slow traffic. Bit bloody annoying but other than that all ok.
Left to cool down and and checked the oil level, fraction under the full level, so ok. Disconnected the fuel lines to check that off was off, no problem no leaks.
The boss said that like me, she had never seen smoke like it other than on an old diesel tractor starting up in the coldest of winter.
Any ideas from the knowledgeable collective ????????
