Description

Tillotson HL-129E 2-Cycle Gas Carburetor – Compact Performance for Rookie Classes & Small Engines


Versatile Diaphragm Carburetor for 2-Cycle and Restricted 4-Cycle Racing

The Tillotson HL-129E Carburetor is a compact, gas-fueled diaphragm carb originally designed for Pioneer chainsaws, but it has proven itself as a reliable performer across a wide range of racing and recreational applications. Commonly used on 50cc 2-stroke engines, it’s also adapted for 5hp Briggs Flathead 4-cycle engines in restricted racing classes like Jr. Sportsman, Rookie, or fun kart categories where performance needs to be balanced with control and safety.


Featuring a manual choke system for easy cold starts and consistent idle, the HL-129E uses a standard volume (single stack, gas) pump stack, making it ideal for smaller displacement engines. Its diaphragm-based fuel delivery systemoffers smooth and consistent metering, especially on bumpy tracks or where engine angle and vibration vary.


Whether you're tuning a rookie kart or need a reliable gas carb for small 2-cycle setups, the HL-129E delivers dependable performance with simplicity and serviceability.
