Index of Problems and Solutions
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 o ur 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 c harger at 4.12 amperes.The battery is located under the frame, next to the turbine.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.
