This carburetor kit for the smallblock Lambretta engines of the 125-190cc class is a handy piece of kit if you need to upgrade from the old-fashioned SH carb.
Race exhausts, porting work to the cylinder and similar often ask to much of the simple SH carb and its limited set up range
The PHBL Dellorto 25mm offers a much wider adjustment ability, especially in the needle and idle jet setting range.
The piston ported engines respond very happily to larger carb diameters. Not only offering more power, but better thermal consistency as well due to the better inner cooling.
Another advantage is that you can use the carb with the original elbow and air filterbox outfit. This supports a low noise level and underlines the classic standard look of the bike.
To have the maximum air flow, the elbow under the seat should be modified or dismissed.
The throttle cable should be routed without kinks for perfect function.
With the very handy main jet set, idle jet set and carb needle set it is very easy and uncomplicated to adjust every engine from the standard Li125 to larger cc ported conversion cylinders.
