Frequently asked questions
Use only a good quality gasoline, free from dirt and water. The fuel should have an octane rating of at least 90. Using low octane gasoline can cause the engine to detonate or knock, which can damage the engine.
The oil filter should be replaced after every other oil change. If operating conditions are extremely dusty, replace the filter after every oil change.
The engine is cooled by air circulated by a fan-flywheel. Make sure the cylinder shrouding is clear of dirt and chaff to ensure proper air flow. If the engine is still overheating, check the cooling system for any blockages or other issues.
The oil pressure is controlled by a relief valve. You can adjust the pressure while the engine is running by removing the outer lock screw and using an Allen wrench to adjust the spring tension.
The fuel pump is actuated by an eccentric on the camshaft. To prime the pump, move the hand lever up and down until you feel a distinct resistance.
