Lawn Mower
Parts Used:
Ring Set-Standard - 499425
Carburetor Overhaul Kit - 498260
Screw - 691340
Gasket Set-Engine - 590508
Repair Difficulty:
Medium
Time Spent Repairing:
More than 2 hours
Tools Used:
Screwdriver, Pliers, Power Drill, Socket set, Wrench Set, Nutdriver, Adjustable Wrench
Burning oil, low power, hard starting
1. Removed engine from lawn mower base
2. Disassembled engine - during disassembly the muffler bolts snapped, so both needed to be drilled out and then helicoiled
3. Using bore gauge, measured three points in piston bore for size and roundness - determined that standard ring set fell within measured limits based on Briggs & Stratton technical information available on the internet
4. Broke glaze in piston bore and removed small ridge at the very top of the bore
5. Lapped valves to seats and measured tappet to valve clearance and adjusted clearance by grinding valve stem to achieve clearance suggested by Briggs & Stratton technical information
6. Installed rings onto piston and measured crankshaft ODs
7. Installed crankshaft and piston
8. Completed engine assembly using new gasket set
9. Rebuilt carburetor and installed
10. Completed engine assembly and installed engine onto lawn mower base
The important items to keep in mind:
- all parts must be cleaned thoroughly to include bolts
- all critical IDs and ODs must be measured and determined to be within limits
- all gasket surfaces must be cleaned of old gasket material
- even though it is important to follow torque specifications, following a cross hatch method of tightening bolts without a torque wrench can be done - it just takes an educated touch
- there are great exploded views of assemblies all over the internet, so there is no need to worry if you can get the parts back together

    OEM parts and excellent service
    I originally ordered this gasket set along with several other repair parts for my small engine repair. All parts were Briggs and Stratton OEM and fit perfectly. The first gasket set shipped was incorrect but after contacting ereplacement by phone the correct set was shipped immediately and I was provided a return label for the incorrect set which I shipped back at no cost to myself. While I had to repurchase the correct gasket set, I received a very prompt refund on the incorrect gasket set with no hassles and no additional contacts required to receive the refund. Instructions with the parts were helpful in allowing me to do a DIY repair on this engine which saved me significant money over having the repair done in a shop or purchasing a replacement unit.
