Nice job Stelios, like the spark plug cap and the throttle lever...
The tank is incorrect, but we can live with that. Those tanks straps are wrong for the engine, and as others have noted the clutch lever is upside down and on the wrong side. The brackets holding the tank to the block should be cast alluminium ones, but they are hard to find. Nice to see the correct grip on the tiller.
The flywheel nut is not quite right, I am going to make some new ones, so when I do I'll send you one. Also I assume you are going to make a copper fuel pipe to the right shape?
Keep up the good work! Somebody with a tank for sale really ought to offer you a good deal...the straps are available in stainless or zinc plated on ebay.
