Be careful here because a good file will remove the valve stem metal fast. You have to file metal off the end of the L-head valve stem to set the clearance. You can review such on-line about re-staking valve seats and setting the valve clearances and other info on you tube. It's common for the single cylinder Briggs engines STEEL valve seat to come loose in the block and require re-staking and also the valve stem clearance to get too close.

You can use a rubber tipped air nozzle gun to inject into the spark plug hole just holding it by hand at 20#'s. It will be normal to hear air going into the crankcase past the rings, but no air should be coming out the muffler or carb when at TDC compression stroke.

With compression that low and If you have access to a air compressor or air tank lock the engine at TDC compression stroke and inject about 20 lbs (not over 20) of air pressure into the spark plug hole and listen at the muffler and carb for a air leak. Check the compression on your good engine and you will see the difference. A single cylinder L head Briggs should have at least 80. I am at the end of my diagnostic expertise in this.Д¬an someone direct me to the next step in figuring this frustrating problem. I realize this is an old generator, but it gets limited use, normally less than once a year, and more importantly I have to figure out why it will not start or it will drive me nuts.

It seems like a fuel delivery issue since I have spark, but the starter fluid and manual pour of gas in the cylinder should allow a start if it is strictly a fuel problem (I would think) Checked to ensure the piston is moving up and down and the valves are moving smoothly. Opened the head and verified there are no head gasket leaks or cracksДЁ. Sprayed starter fluid in the carb and actually poured a ВЅ cap of gas in the spark plug hole without success.Д§. Cleaned all the contacts on the on-off switch.Д¦. Verified there is oil in the engine, and overrode the low oil cut off to test.ДҐ. The know working carb, coil and spark plug from the WORKING generator, when placed in the NON WORKING generator do not solve the problem.Д¤. The carb, spark plug and coil from the NON WORKING generator work perfectly in the WORKING generator. In an attempt to isolate the problem, I exchanged the carb, coil and spark plug from the WORKING generator. Verified that there is spark at the plugДЈ. Verified that the fuel is good and the filter is clearДў.

During the recent power outage after Irma, I ran them both about 14 hours per day, turning them off at night to conserve gas.ДЄfter 8 days, one of the generators would not start, and I am at my wits end in trying to diagnose the problem. Both have Briggs & Stratton 10 HP engines. I have a 2 nearly identical Coleman 5500 generators from the 1990вЂ™s.
