I am new here and just got my 1978 Blanco after restoration. Motor had 300 original miles so was not opened but everything has been cleaned (fuel tank, new gas line, carb, filters, cables, new pipe...). the first 30 miles went perfect but since, randomly, the motor wants to stall (and sometimes stall) when I want to accelerate from a stop. I also feel it drops while I am riding and pull the throttle. It drops before picking up again.
Oil mix is 32:1 regular gas and my carb is a Dellorto SHA 14 12. It holds idle very well.
Thanks for your help
