G260PUM Marine Engine – with Walbro WT-813A Carburetor | Zenoah

$239.95

– New generation 25.4cc displacement gas engine. Features an all-new cylinder design w/4 transfer ports for improved torque & high-RPM performance.

– This lightweight, compact engine has a redesigned combustion chamber & new single ring piston. Includes water jacket, velocity stack & recoil starter complete from the factory. Factory rated at 2.89HP.

– Approaching 4HP@14,000 RPM w/ Bonzi Tuned Pipe

– Includes (1) Walbro WT-813A big bore carburetor for increased performance featuring an accelerator system. It has a modified throttle shaft pre-installed for maximum compatibility.
Zenoah recommends this for upgrading your engine.

Engines with the standard carburetor (WT-603, WT-644, etc) tend to experience a lag in low-end acceleration when tuned for peak power.
The new carburetor includes an internal acceleration pump to allow faster recovery as throttle increases.

WT-813A Specs:
Venturi Bore: 12.7mm
Throttle Bore: 15.84mm
Primer Bulb: Yes
Choke: No
Mounting hole’s distance between centers: 31mm
This is IN PLACE of the stock WT-644 carb.

Looking to run this engine with a clutch / water pump set up? Be sure to have us drill and tap the engine for only $5!

Be sure to add a bottle of Bonzi Break-in Oil – it is formulated to get the max performance out of your stock or modified engine by properly seating the ring to the cylinder through what is known as a scuffing process.
Most 100% synthetic oils are so slick that they do not allow this process or take an extremely long time to do so.

Just mix 5 ounces to one gallon. Bonzi Break-in-Oil allows for complete break-in in just one gallon.
