Procedures
12Adjust Governed Idle Speed adjustment
Tools: Tachometer
- Hold governor lever away from carburetor so throttle lever is against idle speed screw.
- Start engine and warm up; adjust screw to approximately 1200 RPM.
- Release governor lever and check throttle lever is in idle position.
- Turn governed idle adjustment screw to obtain equipment manufacturer recommended idle speed (1500-1800 RPM).
- Move throttle lever to wide-open/full throttle and set high speed screw to intended no-load RPM.
Adjust Low Idle Fuel adjustment
⚠ Do not attempt to remove limiter caps.
- Place throttle control into idle or slow position; adjust low idle speed to 1200 RPM.
- Turn low idle fuel adjusting needle out (counterclockwise) until engine speed decreases (rich); note position.
- Turn needle in (clockwise); note position where speed decreases (lean).
- Set adjusting needle midway between rich and lean settings.
- Repeat for other low idle adjustment needle on two-barrel carburetor.
- Recheck/adjust low idle speed to specified setting.
Adjust Low Idle Speed (RPM) adjustment
Tools: Tachometer
- Place throttle control into idle or slow position.
- Turn low idle speed adjusting screw in or out to obtain 1200 RPM (± 75 RPM).
- Check speed using a tachometer.
Carburetor Low Idle Fuel Adjustment adjustment
⚠ Do not attempt to remove limiter caps.
Tools: tachometer
- Place throttle control into idle or slow position; adjust low idle speed to 1200 RPM.
- Turn low idle fuel adjusting needle out (counterclockwise) until engine speed decreases (rich); note position.
- Turn needle in (clockwise) until engine speed decreases (lean); note position.
- Set adjusting needle midway between rich and lean settings.
- Repeat for other low idle adjustment needle on two-barrel carburetor.
- Recheck/adjust low idle speed to specified setting.
Clutch Adjustment (wet disc type) adjustment
⚠ Do not attempt to pry or force spring lock away from ring.
Tools: large screwdriver
- Release clutch and remove nameplate. Using a large screwdriver, turn adjusting ring clockwise, one notch at a time, until firm pressure is required to engage clutch.
- After adjustment, engage clutch and check that rollers go over center to lock unit in engaged position and prevent releasing under load.
- If trouble persists after readjustment, clutch reconditioning is indicated.
Determining Camshaft End Play adjustment
Tools: camshaft end play checking tool, feeler gauge
- Install shim removed during disassembly onto camshaft.
- Position camshaft end play checking tool on camshaft.
- Apply pressure on checking tool (pushing camshaft toward crankshaft). Use a feeler gauge to measure camshaft end play between shim spacer and checking tool. End play should be 0.076/0.127 mm (0.003/0.
- If end play is not within range, remove checking tool and replace shim as necessary.
- Reinstall end play checking tool and recheck end play.
Digital Linear Actuator (DLA) Adjustment adjustment
Tools: Torque wrench
- DLA must be in fully retracted position during assembly.
- Loosen DLA mounting plate screws located on top of actuator plate.
- With throttle linkage centered in U-Clip or secured with retaining clip at end of DLA shaft, slide DLA bracket assembly back until throttle plate is fully open.
- Torque mounting plate screws to 2.5 N·m (22 in. lb.).
Governed Idle Speed Adjustment adjustment
Tools: tachometer, pliers
- Hold governor lever away from carburetor so throttle lever is against idle speed adjustment screw. Start engine and warm up, then adjust screw to approximately 1200 RPM using a tachometer.
- Release governor lever and check throttle lever is in idle position. Turn governed idle adjustment screw to obtain equipment manufacturer's recommended idle speed (1500-1800 RPM).
- Move throttle lever to wide-open/full throttle and hold. Turn high speed screw to obtain intended high speed no-load RPM.
Governor Initial Adjustment adjustment
⚠ Do not tamper with governor setting. Overspeed is hazardous and could cause personal injury.
Tools: Torque wrench
- Make sure throttle linkage is connected to governor arm and throttle lever on carburetor.
- Loosen nut holding governor lever to cross shaft.
- Move governor lever toward carburetor as far as it will go (wide open throttle) and hold in this position.
- Insert a long thin rod or tool into hole on cross shaft and rotate shaft counterclockwise (viewed from end) as far as it will turn, then torque nut to 6.8 N·m (60 in. lb.).
Governor Sensitivity Adjustment adjustment
- To increase sensitivity, move spring closer to governor cross shaft.
- To decrease sensitivity, move spring away from governor cross shaft.
High Speed (RPM) Adjustment adjustment
Tools: Tachometer
- With engine running, move throttle control to fast.
- Turn inner adjustment screw outward to decrease, or inward to increase RPM speed.
Ignition Module Air Gap Adjustment adjustment
⚠ Do not attempt to set the gap with a business card or folded microfiche card. Use the feeler gauge specified.
Tools: Feeler gauge 0.30 mm (0.012 in.), Torque wrench
- Turn flywheel magnet away from module position.
- Attach module to mounting legs, pull it away from flywheel, and 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, and retighten mounting screws.
- Rotate flywheel to remove feeler gauge, position magnet back under module, and recheck gap minimum 0.28 mm (0.011 in.) under each leg. Torque screws to 4.0 N·m (35 in. lb.).
