-"F" SERIES STARTER-

REPLACING STARTER ROPE

Unwind starter rope, rotate pinion gear out against washer and retaining ring. Pull knotted end of rope out using needle nose pliers as shown and untie o r cut knot off.

REMOVING STARTER ASSEMBLY

To remove the complete starter assembly on "F" series engines proceed as follows:

1. Remove' engine shroud, primer and fuel hoses. Disconnect switch leads.

2. Remove starter rope handle and allow rope to gradually recoil through hole in top of the air baffle.

3. Using an Allen wrench loosen the socket set- screw securing starter shaft to engine and remove starter assembly.

“F” SERIES STARTER

Thread new rope through hole, tie overhand knot, pull knot down into the recessed cavity. Wind rope clockwise with the pinion facing you.’ Pigtail on knot must be tucked into cavity as shown.

When installing a new starter pinion spring it should be stretched only far enough to allow it to snap into the groove of the nylon starter pinion. A distorted spring will not grip the pinion properly and will possibly jump off and become lost. The prongs of the starter pinion should be approxi- mately 1/4” or less apart when the spring is off the starter pinion.

ROPE BREAKAGE

Rope breakage or “cutting” can’ normally be attrib- uted to rough surfaces, sharp nicks or edges inside rope guide hole or pulley. Use old piece of rope with grinding compound or other abrasive to smooth sharp surfaces.

“F” SERIES STARTER

Reassemble spring in anchoring channel of pulley and push pin of pin and cup assembly through the pulley opening. Make sure the spring is guided into the slot in cover.

DISASSEMBLY OF STARTER

With starter assembly on bench, flat side down, remove retainer ring with a screw- driver. Remove pinion gear from pulley.

Never ‘lubricate pulley keep it clean and dry.

SAFETY WARNING

THERE IS STILL TENSION ON STARTER SPRING. TO REMOVE TENSION HOLD TWO HALVES TO- GETHE’R, POINTING SHAFT DOWN- WARD. NOW DROP ASSEMBLY ON

WARD). HALVES WILL SEPARATE AND RELEASE SPRING.

FLOOR (SHAFT POINTING DOWN-

Examine starter spring carefully for bent or weak- ened areas Spring steel is quite brittle and is damaged easily if bent or twisted. A light coating of Lawn-Boy “A” grease must be applied before reinstalling.

“F” SERIES STARTER Grasp pin and cup assembly and wrap your fingers over starter pulley to hold two pieces together. This will keep the spring contained so that you can rotate pulley in a clockwise manner, winding spring. Continue winding until spring is drawn into cover and hook rests in slot. Carefully let spring unwind slowly until it is relaxed.

Be sure ends of starter pinion spring are hooked on the die cast spring guide of the C.D. bracket.

Check to make sure rope retainer is even with C.D. mounting bracket as shown. Se- curely tighten socket setscrew.

CORRECT STARTER SPRING PRELOAD

If the end of the rope is in segment@ wrap rope by the rope retainer one time.

If the end of the rope is in segment@ wrap rope by the rope retainer twice.

When starter rope is pulled all the way out, the pulley must still turn before bottoming of the recoil spring occurs. Otherwise, re- coil spring life will be reduced.
