This may be moot but here are a few things to look at when a Guzzi carb
model sits for a long time.

Is the fuel new?
Is the inside of the tank clean?
Is the fuel filter blocked?
Float bowls clean and banjo bolt screen clean?
Is the distributor adjustment bolt tight?
Does it have a kill switch? Is the switch defective?
Plugs wires cracked?
Distributor cap cracked?
Inside distributor, rotor clean?
Points and Point plate tight?
Ignition wires tight, undamaged?


As well as the valve issue brought up by Patrick
Good Luck

This bike sat a long time. Was it torn apart? Did you have the heads
off? If the heads were off and new gaskets applied, the first few heat
cycles will dramatically swell/shrink the metal mass and alter the valve
settings dramatically. I usually take a new motor, start and run for 5
or 10 minutes, cool overnight and re-torque before running again. The
valves have to be re-adjusted AFTER the torque process. Do it all again
at 100 miles and 1000 miles.
