Magnetron Ignition

Remove Armature

The best means of testing Magnetron™ armatures is on the
engine. Before replacing the armature, be sure that the
problem is not in the wiring, the safety/engine stop switch,
the neutral switch or speed limiter.

Inspect Valve Springs

Replace broken, distorted or worn valve springs.

Inspect Valve Guides

1. Check valve guides for wear using Reject Gauge Tool

(#19122)

.

2. If flat end of gauge can enter guide for 1/4" (6.35mm)

or more, valve guide is worn. Replace the cylinder
head.

3. If plug gauge is not available, replace the cylinder head

if the valve guide exceeds .267" (6.78mm).

Finish Ream Valve Guides

NOTE:

The following procedure is recommended

to assure that the entire guide is clean and free of
foreign material.

1. Use Finish Reamer Tool

(#19096)

and Reamer Pilot

Guide Tool

(#19191)

to remove foreign material or

burrs from guide.

2. Use Stanisol® or kerosene to lubricate reamer.
3. Ream through entire guide.
4. Keep turning reamer clockwise when removing

reamer.

5. Flush out all reaming chips.

Reface Valves and Seats

Valve faces can be resurfaced using a commercially available
valve grinding tool. Briggs & Stratton does not recommend
this practice as a high quality repair procedure. Valve
replacement is recommended for damaged or worn valves.
Valve seats

(Figure 65B)

are cut to 45° using Tool

(#19237)

or

(#19343)

, “Neway Valve Seat Cutter Kit®”.

Valve and seat are lapped in using Valve Lapping Tool

(#19258)

and Valve Lapping Compound

(#94150)

to

assure a good seal between the valve face and the seat.

1. Thoroughly clean lapping compound from valve seat

and valve face.

2. Valve seat width should be as shown

(Figure 65B)

.

3. If seat is wider, a narrowing cutter should be used. If

valve face is badly burned, the burned valve should be
replaced.

4. Replace valve if margin

(Figure 65A)

is less than

1/32" or is damaged

.

5. Valve seat width

should be 3/64 - 1/16". If the seat

width is not within specification, or if the seats are
burned or damaged, replace cylinder head.

Remove Piston Rings

Remove piston rings using Piston Ring Expander

(#19340

)

as shown

(Figure 66).

NOTE:

Some oil control rings consist of two thin

steel rails and a spring expander. The steel rails
cannot be removed with the piston ring expander.
