Procedures
12Adjust Ignition Module Air Gap adjustment
⚠ Do not attempt to set air gap with a business card or folded microfiche card.
Tools: Feeler gauge 0.30 mm (0.012 in.)
- Turn flywheel magnet away from module position.
- Attach module to mounting legs, pull away from flywheel, tighten screws temporarily.
- Rotate flywheel so magnet is centered under module.
- Position a 0.30 mm (0.012 in.) feeler gauge between magnet and all three legs of module.
- Loosen mounting screws, allow magnet to pull module down against feeler gauge, retighten screws.
- Rotate flywheel to remove feeler gauge, recheck specified gap under each leg; torque module screws to 4.0 N·m (35 in. lb.).
Adjust Low Idle Fuel and Speed adjustment
⚠ Carburetor adjustments should be made only after the engine has warmed up.
⚠ Certified engines may have a fixed idle or limiter cap; do not attempt steps 1 and 2.
Tools: Tachometer
- With engine stopped, turn the low idle fuel adjusting needle in (clockwise) until lightly bottomed.
- Preliminary setting: turn the needle out (counterclockwise) 2-1/4 turns from lightly bottomed.
- Run engine at half throttle 5-10 minutes to warm up; verify throttle and choke plates fully open.
- Low idle speed: place throttle in idle/slow; set low idle speed to 1200 RPM (± 75 RPM) with the low idle speed screw.
- Low idle fuel: turn the low idle fuel needle in slowly until engine speed decreases, then back out approximately 3/4 to 1 turn.
- Recheck idle speed with a tachometer and readjust as necessary.
Adjusting Low Idle Fuel and Speed adjustment
⚠ Carburetor adjustments should be made only after the engine has warmed up.
Tools: Tachometer
- With engine stopped, turn low idle fuel adjusting needle in clockwise until it bottoms lightly.
- Preliminary setting: turn adjusting needle out counterclockwise 2-1/4 turns from lightly bottomed.
- Start engine and run at half throttle 5 to 10 minutes to warm up.
- Place throttle control in idle/slow position and set low idle speed to 1200 RPM (±75 RPM) using tachometer.
- Turn low idle fuel adjusting needle in slowly until engine speed decreases, then back out 3/4 to 1 turn.
- Recheck idle speed with tachometer and readjust as necessary.
Governed Idle Speed Adjustment (If equipped) adjustment
Tools: Tachometer
- Hold governor lever away from carburetor so throttle lever is against idle speed screw; start and warm engine, adjust screw to approximately 1200 RPM.
- Release governor lever; turn governed idle adjustment screw to obtain manufacturer's recommended idle speed (1500-1800 RPM).
- Move throttle lever to wide-open/full throttle and turn high speed screw to obtain intended high speed no-load RPM.

⚠ Engines will have fixed low idle or limiter caps; do not attempt to remove limiter caps.
- Place throttle in idle/slow; adjust low idle speed to 1200 RPM.
- Turn low idle fuel adjusting needle out (counterclockwise) until speed decreases (rich); note position.
- Turn needle in (clockwise) until speed decreases (lean); note position.
- Set adjusting needle midway between rich and lean settings.
- Repeat on other low idle adjustment needle (two-barrel only).
- Recheck/adjust low idle speed to specified setting.
Low Idle Speed (RPM) Adjustment adjustment

Set Ignition Module Air Gap adjustment
Tools: Feeler gauge 0.30 mm (0.012 in.), Torque wrench
- Rotate the flywheel to position the magnet away from the ignition module bosses.
- Install each module to the crankcase bosses; slide modules up away from the flywheel and snug the screws.
- Rotate the flywheel to position the magnet directly under one module.
- Insert a 0.30 mm (0.012 in.) flat feeler gauge between the magnet and the module.
- Loosen the screws enough to allow the magnet to pull the module against the feeler gauge.
- Torque the module screws to 4.0 N·m (35 in. lb.).
- Repeat for the other ignition module.
- Rotate the flywheel back and forth and check the gap with a feeler gauge; final air gap 0.280/0.330 mm (0.011/0.013 in.).
