Minimizes creep and resets with seals on both needles and a ratchet spring on the high-speed needle. A rotor guide screw eliminates spring-related movement, too.

Includes a lock nut and a longer crankshaft with more thread length to ensure better prop nut engagement and greater pilot safety.

Includes glow plug, muffler, cable extension.

The ABL (Advanced Bi-Metallic Liner) includes one layer for better bonding, and another to reduce wear and extend life.

A needle-valve extension cable and rear-angled high-speed needle maximum pilot safety and convenience.

A generously sized chamber and larger sound baffle help the Power Box muffler significantly reduce exhaust noise without compromising power. Rotatable exhaust outlet provides effective, no-cost finish protection.

 

Recommended Propellers: 10.5x6, 11x6-8, 12x6-7, use 10x6 for break-in

 

Simple, side-exhaust design.

Power Box muffler features a squared-off shape for easier fits in more cowls.

40K carburetor has high- and low-speed needles, plus a mixture adjustment screw. Tighter tolerances between the piston and ABL create a tighter compression seal and improved power.

Dual ball bearing-supported crankshaft lowers friction and wear.

Head automatically centers and levels itself and snugs down with just 4 screws.

Subtly tapered low-end needle eliminates surging at transition, ensuring smooth, controllable power across the rpm range.

Updated liner ports and a ball-milled inlet port minimize turbulence and promote better fuel/air mixing.
