Hello guys, i have a 1965 Mercedes 230 w110 fintail with the M180 6cyl. Dual carbs. I brought this car out of the grave and refreshed the engine changed the coolant did tune up,etc. Started up. Its auto. Someone recently looked at my engine an said my harmonic balancer is bad. I don't know what to do now. I have looked everywhere and cannot find one for my car. Ive been stuck in this stage for a few months and i havent ridden it for about 2 months, since i don't want to ruin my engine. Please help! Thank you for your time.
