I have found the error, it is not a correct camshaft in the engine. This camshaft must be to a engine wth 1 carburetor. The inlet and exhaust valves on cylinder No. 2 and 3 opens in wrong order. Does anyone have a Holbay camshaft for sale?
Hi Now I have tried to start my Holbay replica engine, but there is a problem that I need some help with. It blows out the exhaust from the carburetor from the cylinder 2 and 3. I have checked the valve clearance, ignition sequence, and compression, this is ok. Cylinder 1 and 4 is ok Can I have installed a wrong camshaft? it is bought as original Holbay. It is marked: MC 24002 N, 1981079, and R. Does anyone have any good advice? Best regards Jan, Norway
