Hi. My 121 (a B18A with one ZS 175CDS)has high idle (1500 rpm) after a full overhaul. The culprit was air leaking between the carb and the manifold. I put a bit of gasket seal on that gasket and press a bit more the nuts.

Need to plug the tube coming from the distrib for timing measurement.

Also, old engines due wear has different timing settings. On 121s (with carbs, no damm computer gadgets) we advance timing up to feel pinging driving with load aboard (like go up to a hill), after it, we retard the timing a bit up to the point the pinging are gone.

¿Your dizzy are black/rusted or aluminium?

Happy Volving
