To check the magneto on a Tecumseh 5 HP engine, first ensure the engine is off, then remove the spark plug and inspect the magneto for cracks or damage. Use a multimeter to test for continuity; if there's no continuity, the magneto may need replacement. For timing, rotate the engine to the point where the piston is at the top of its stroke (top dead center), then check the magneto's points gap and ensure they open at the correct time relative to TDC, usually around 1/4 inch before the piston reaches TDC for ignition. Adjust the timing if necessary by loosening the magneto and repositioning it.
To set the timing on a Fairbanks magneto, first, ensure the engine is at top dead center (TDC) on the compression stroke for the cylinder you are timing. Next, remove the magneto cover and locate the timing mark on the rotor. Rotate the magneto until the timing mark aligns with the reference mark on the engine, then adjust the ignition points or impulse coupling as necessary to ensure they open at the correct time. Finally, reassemble the magneto and check the timing with a timing light if needed.

The Tecumseh OHH60 engine typically uses a Tecumseh carburetor model 632347 or a compatible replacement. It's crucial to check the specific engine model and serial number to ensure the correct fit, as variations may exist. Always consult the engine's manual or a trusted parts supplier for precise compatibility.
Timing light. The instructions are on the engine hood.
You can set the base timing by ear, But to be able to get the check engine light to go out and to set the timing were it is supose to be requires a engine scanner. The computer controlls the timing on that year engine.
What year F250 and what engine??
Basically, the timing is set and adjusted by the engine computer.
The timing on that year engine is computer controlled and you must have an engine scanner to set the timing. That engine has a cam and crank sensor and they must be in correlation / TIME with each other. Are you will have a check engine light on and poor performance.

Check your engine timing, it may be too slow.
Maybe, it depends on if your engine is an interference engine.
The magneto gap for a Yamaha Banshee, specifically the 350 model, is typically set at 0.012 to 0.014 inches (or about 0.3 to 0.35 mm). This gap is crucial for ensuring proper ignition timing and optimal engine performance. It's important to check and adjust this gap during maintenance to ensure reliable operation. Always refer to the specific service manual for your Banshee for the most accurate specifications.
