Description -

Tillotson Stock Carburetor
The PK-1 carburetor is legal for AKRA and many other racing divisions.
The Tillotson PK-1A fits most of the 196cc 6.5hp clone engines, including Honda GX200, Ducar 196, Ducar/Tillotson 212E, Tillotson 196R/RS, Tillotson 212R, Ducar/Tillotson 212E, Predator 212, and BSP 196 and 212 engines.

Key Standard Features:

The venturi is machined to .613" +/- .001" - very close to the .615" no-go rule. Additional boring is not necessary.
The throttle shaft alignment is made to the centerline of the bore.
The emulsion tube is of a 24-hole progressive design.
Main jet: .039"
Low side jet: .028"
Low side air bleed: .055"
High side air bleed: .043"

The jetting above is a general starting point for all different types of racing. This combination was based on a stock rule clone using a CL-1 camshaft, turning a maximum RPM of 6,100 with 10.8 springs.

If you have a current 2017 built AKRA stock clone engine with a ported head, CL-3 type camshaft with 10.8 spring and 37-degree flywheel advance, and it's turning ~7,000 RPM or more, you may use a .034"-.037" low side jet and .036"-.039" main jet. Caution: Using this combination, your idle may be rough, and there is a chance of loading up if it idles for too long.

Mini bike racers: We recommend trying the carburetor as is. If idle is too rough, you may need to purchase a .020" low side jet.
