7. TROUBLESHOOTING
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.
