CARBURETOR
Before all please remember that
: about all problems you can have comes from the filter inside the carburetor !
The main setting of our carburetor is obtained
by the adjusting of the of the spring that controls the opening of the needle valve placed
under the trace E.
The TOP 80 standard setting, is 1,2 /1,3 Bar on opening (pop off
pressure)
you can
measure it by the standard instrument for the adjusting of diaphragm carburetors (see
picture below)
You can order it at Per Il Volo
contact us or our dealer for more explanation.
A finer carburetor setting can be done by adjusting the height of the trace E from the carburetor's plane.
Our basic setting is a height of 0,5 / 0,7 mm (about half of the height of the plane considering the lid's holes).
Since this is not an easy adjustment we strongly recommend you to turn to an expert:
An intake anti-dust filter riches the the mixture at medium-high revs.
