Engine Related Parts

Engine Parts Note: The following parts are those commonly found on the B&S engines of many vintage Gilsons. While many parts remained consistent there can be variations especially at the out years. It is suggested that you download a PDF of your engine's breakdown and confirm all part numbers. Note that some numbers in the PDF document have changed over the years but they should be traceable to the items you order. You will see that many of these suggested parts reference the older numbers they replace. If you have a part number or don't find what you need below enter the part number or keyword here.

This kit includes all you need to replace the 1/4" ID fuel line and filter found on 6, 7 or 8 HP Briggs & Stratton engines. Hose deteriorates with age and ethanol is not helping any. This fuel line is safe for ethanol blends of 10% and higher! Hose length supplied is 2 feet so you can trim to fit your shrouding since they vary. 150 micron filter and 4 clamps are included. Most of these parts are available below individually from M&D Mower if you prefer.

Fuel Valve Kit
This kit includes the valve and clamps to add an inline fuel shut-off to engines with 1/4 inch fuel line. This includes 6, 7 and 8 HP Briggs & Stratton engines. It can be installed with the fuel line kit found above. A fuel line shut-off can be desirable if you are concerned about carburetor fuel weeping. On units with electric start the factory valve is often inaccessible and certainly is not mitten friendly. This valve can be added for convenience.

Ignition Related Parts
Spark plug boot

These are frequently lost or damaged but not expensive or difficult to replace.


These are the conventional points found on most pre-1981 engines. If your engine is 1966 or older be sure to consult a B&S parts breakdown since yours may be different. Flywheel tools, see below are required to do this job properly.

Mega-Fire Ignition Module

This kit allows you to upgrade your pre 1981 engine that does not have the Magentron (solid state) ignition. The change to maintenance free is nice but the beauty for the do-it-yourself mechanic is that you need not remove the flywheel to install this system. Without the need for expensive flywheel tools an ignition repair is now easy for any capable shade tree mechanic.

Tool, Books and Supplies
Recoil Clutch Tool

Combined with your torque wrench and engine manual specifications you can get your clutch off and on easily and torqued so the safety key functions properly.

Add the following tools for a 1st class job:

8 Ounce STA-BIL
STA-BIL ETHANOL TREATMENT. Fuel Stabilizer, 10 ounce

Adding stabilizer to your fuel keeps gasoline fresh and retards the formation of damaging deposits in your fuel system. This is much more important for a single cylinder engine than a regularly used automobile. This special Ethanol formula helps manage the effects of ethanol blend fuels. This will enhance perormance and help prevent costly fuel system damage. Add to your storage can before heading to the filling station and it will come home well mixed. I use STA-BIL in all of my outdoor power equipment all of the time. That way I never need to worry about what is in a machine when storage time comes. STA-BIL ETHANOL TREATMENT. Fuel Stabilizer, 4 ounce

These are actual manufacturers publications and include all of the required torque values and test specifications.

Valve Spring Compressing Tool

This tool is worth the price even if you only use it once in your lifetime. Working to compress valve springs and set the clips using pliers, screwdrivers and wedges is fools errand. With this tool it becomes an easy task. If you have one of the engines from the 1960s with the split cones as part of the exhaust valve retainer this tool is an absolute "must have".

Valve Seating Tool

With this tool and some Valve Lapping Compound you can restore the finish of the valve / seat interface. Remember to reset the valve gaps per your engine manual when doing this job. Also plan to have a valve cover gasket and an intake elbow mounting gasket on hand.
