| Pros | Cons | |------|------| | Very durable, long service life | Not fuel-injected – cold starts on gasoline can be fussy | | Cheap parts and rebuild kits | Heavy compared to modern engines | | Runs on propane (cleaner for indoor use) | Low max RPM (not for road vehicles) | | Simple electrical system | Emissions non-compliant for new equipment (pre-Tier 4) |
Diagnosis: The idle mixture screw on the LPG carburetor (mixer) is plugged, or the idle cutoff solenoid has failed. Fix: Remove the idle air bleed screw and clean with carb cleaner. Listen for a "click" from the idle solenoid when the key is turned on.
