The engine is very tidy. I have shown a few pics of the piston through the exhaust port, to indicate the condition of the piston.
The head / barrel have some tiny nibbles on the fins as shown. This is a lovely Levis Popular 211cc engine. I have some Amac carbs that might suit this. They will be listed separately.They are equally as nice. It is at PE28, near St Ives in Cambridgeshire. If you don't see a price, please ask. If you can't collect for a while, it's not a problem.
However, I will need to be paid very soon after the sale. This item is in the category "Vehicle Parts & Accessories\Motorcycle & Scooter Parts & Accessories\Engines & Engine Parts\Complete Engines". The seller is "daosb27" and is located in this country: GB. This item can be shipped worldwide.
