Briggs & Stratton Engine -4.5 How to Change a (Primer>) Red Bulb on a Lawnmower

That's easy man! You will always hear, "You sir, need to gap this or that at EXACTLY .00071542 inches per square meter".

The actual "poor boy fix"-

Put your magneto back on there, and stick a business card from your wallet in between it and the rotor. Let the magneto pull itself to it, you center it, and give it just a hair of breathing room (to slide the card back out). Tighten 'er down, and you got it.

1.- If you can't pull the card out, it is too tight.

2.- If you pull the card out easily, too loose.

3.- JUST enough to pull it out, and have it drag just a bit on the way out is JUST ENOUGH!

Remember, on 4-strokes, they ARE forgiving, and can do miracles even if you try your best to destroy them.

Your engine model # 128602 Type 0212-E1. Forget about ordering from Sears and paying shipping and waiting a week. Go to your local Briggs and Stratton dealer (most shops are) and buy part # 694395. Should cost about $3.00

pull the bulb and retaing ring any way you can. don't try ti save them. you get a new retaing ring with the bulb. put the new bulb in then work the retaing ring in with a screw driver,clean everything behind the bulb before you put the new on in.

to check for firing remove the spark plug insert it in the plug boot and pull the rope while watching to see if the plug sparks be carefull not to touch the plug electrode while pulling the rope or it will shock you. If you don't have a spark, try a different plug. If still no spark the coil could be bad.

What is your engine model number? It should be on a plate on the side of the engine. Your problem is a clogged jet inside the carburetor. Once I have the engine model number, I will be able to give you a carburetor diagram that will show you how to clean it.
