I bought a VW based antique car with a aircooled 1835cc engine. I need to know how to tune the engine. I do not have specs for that engine, valve adjustment, timing, carburators' adjustment. It has a "049" distributor with centrifugal advance (0231-178-009), Bosh Blue Coil, Yellow Spark plug wires, 2- SOLEX BROSOL carburators (H40/44EIS) without a choke, 3/4 grind camshaft, lightened and balanced flight wheel with 8 pins, heavy clutch, electric fuel pump, large capacity oil pump with spin on filter, 165 PSIG compresion in all cylinders. I'm familiar with stock engines but not with midified engines. It starts just fine but seems to starggle to turn over. It has 800 miles since built but I just started it a few times. I have not driven it until I get info on the engine. Any Help would be appreciated.
