EZ-GO golf carts primarily use Robin Subaru engines, specifically the EH29 (295cc) and EH35 (350cc) four-stroke gasoline models. These air-cooled engines feature overhead valves, cast iron sleeves, and maintenance-friendly designs optimized for low-end torque. Since 2014, EZ-GO transitioned to Kawasaki engines in newer models while retaining Robin engines in refurbished/replacement units.

What are the key specs of Robin EH29/EH35 engines?
The EH29 (295cc) delivers 9.8HP at 3,600 RPM, while the EH35 (350cc) produces 11.4HP. Both feature 77mm bore sizes, OHV designs, and centrifugal governors limiting max RPM. Pro Tip: Regularly check valve clearances—0.15mm intake/0.20mm exhaust prevents power loss from thermal expansion.
These engines use splash lubrication rather than pressurized systems, requiring level ground operation. For example, the EH35’s 24mm Mikuni carburetor needs annual diaphragm replacement in humid climates. Transitioning to newer models, EZ-GO now favors Kawasaki’s FX series for improved fuel efficiency, though Robin engines remain popular for rebuildability. But why choose older engines? Their cast iron construction handles ethanol-blended fuels better than aluminum-block alternatives.
| Feature | EH29 | EH35 |
|---|---|---|
| Displacement | 295cc | 350cc |
| HP Output | 9.8HP | 11.4HP |
| Fuel Consumption | 1.2L/hour | 1.5L/hour |
How do Robin engines compare to Kawasaki in EZ-GO carts?
Kawasaki FX engines offer 15% better fuel efficiency through EFI systems versus Robin’s carbureted design. However, Robin units have 30% lower rebuild costs due to simpler mechanics. Pro Tip: For pre-2014 EZ-GO models, stick with Robin engines—retrofitting Kawasaki motors requires ECU modifications.
While Kawasaki’s overhead cam design allows higher RPM ranges (up to 4,200 vs. Robin’s 3,600 limit), Robin engines provide better low-speed torque for hill climbing. Practically speaking, a Robin EH35 can tow 1,100 lbs versus 900 lbs for Kawasaki’s FX440. Transitioning between technologies, consider this: Robin engines act like diesel trucks—torque-focused and durable—while Kawasaki operates like sportscars, prioritizing RPM and smoothness.
What maintenance intervals do Robin engines require?
Follow 50-hour service cycles: change oil (SAE30), inspect drive belts, and clean carburetor jets. Valve adjustments every 200 hours prevent compression loss. For example, neglected EH29 engines often develop starter gear wear from improper valve timing alignment.
Beyond basic upkeep, replace fuel lines biannually to prevent ethanol degradation. Transitional maintenance tip: Use marine-grade stabilizers if storing carts over winter—Robin’s steel carburetor bowls rust faster than Kawasaki’s aluminum components. Why risk engine failure? A $10 fuel treatment prevents $400 carb replacements.
| Component | Service Interval | Cost |
|---|---|---|
| Oil Change | 50 hours | $15 |
| Air Filter | 100 hours | $22 |
| Spark Plug | 200 hours | $8 |

FAQs
Yes, but requires adapting motor mounts—Robin’s 10mm mounting bolts differ from Kawasaki’s 8mm pattern. Always upgrade the clutch for optimal torque transfer.
Do Robin engines support LP/CNG conversions?
Only through aftermarket kits—factory carburetors lack hardened seats for gas compatibility. Expect 15% power loss when running propane.
