SERIES 11 BRIDGED
Externally this carburetor looks identical to the standard
series 11 with the black restrictor cap. The difference is
internal through the addition of a second idle feed passage
with a restrictor as shown. This extra passage improves
run quality during light load engine operation (diag. 22).
NON-TECUMSEH CARBURETORS
DELLORTO CARBURETOR
The Dellorto carburetor is similar to the dual system
carburetor. It has no adjustments and has a primer assist
start. It has a noncorrosive float and the needle is viton
tipped, eliminating the viton seat found in the dual system
carburetor. The angle of the fuel inlet is adjustable and
attached to the carburetor body with a banjo bolt. This
carburetor is used on some TVS rotary lawnmower
engines.
