Nice engine,well packaged and ran first time, the cylinder was slightly loose when recieved but was easily tightened with the supplied alan key and the left hand flywheel runs a little out of true other than that it is a pretty engine to watch running, subseqent runs seem to be a little reluctant perhaps bcause I only have 3 in 1 oil to lubricate it which might cause too much drag. The only other minor problem is that no funnel was supplied to fill the tank through the small filler hole so had to improvise one until I could get a small syringe.
