8. TROUBLESHOOTING
8.1 ENGINE
When troubles occur, be sure to check the simple causes which at first, may seem too obvious to be considered. For example, a
starting problem could be caused by fuel starvation due to an empty propane cylinder or an unopened service valve. If you do
not check for this, starter burnout could result.
Some Troubles and solutions:
Surging idle
To smooth out the engines' idle characteristics, adjustment is provided by an idle screw on the lower left side of the carburetor
as viewed from the operator's position. The screw is bright steel and 1/4" in diameter with a Phillips head on it. Rotating the
screw clockwise will increase the idle speed and this should cure the "surging idle". If it does not, call our customer service.
Engine starts and idles, but will quit as the throttle is advanced
It is possible that the propane tank's service valve is faulty. To check for this, close the valve completely and then reopen very
slowly while you listen for a "click" when the gas begins to travel through the valve. If you hear this very slight noise, the
valve is only partially opening. This allows enough gas through to start and idle the engine, but not enough for full throttle
operation. As the throttle is increased, allowing more air to enter the intake, the engine will quit from fuel starvation. Call
your dealer or the factory for instructions on where to have the service valve replaced. Meanwhile, to get by, you can
continue to open the service valve until you do not hear a “click" and then the engine will run normally. If it does not, call
your customer service.
Starter barely turns the engine over or the solenoid just clicks
The battery is likely low in charge. This can be remedied by recharging the battery using a 12 Volt battery charger at 4.12
Amperes. The battery is located on the left side of the propane tank holder under the battery cover. The positive post is the one
with the RED cable attached to it. Follow the instructions that came with the battery charger. REMINDER: this will continue to
happen unless your engine is run for sufficient time between starts to recharge the battery.
