Hello, your engine may have gummed up fuel in the carburetor. When you leave fuel in an engine for more than about 2-3 months, the ethanol that is added to gasoline nowadays easily breaks down and turns the combustable gas into gummy junk that won’t ignite. The best way to resolve this issue is by having somebody who owns an Ultrasonic Carburetor Cleaner to remove your carb and then let it sit in the cleaner for a while. After it has been in for a while, simply take it out, drain the old gas in the tank, pour new gasoline in, and re-install the carburetor. This should resolve your issue. If it still won’t start, try replacing the spark plug. Spark testers only test if a spark is being created at the ignition module and traveling to the plug, not if it is being released in the cylinder. Hope this helps!
Hello Sir, Apple does offer a free keyboard + Trackpad replacement for eligible models that have not come in contact with any kind of liquid. If I were you I would bring it to an Apple store to see if your model is eligible for the replacement. As to why the problem happened in the first place, I have no clue, my only suggestion would be to check with Apple for a replacement.
Hello, I had this problem once before. Here’s how to fix it (at least, that’s how it fixed for me.) step: 1: go to system preferences, locate the tick-box for “sticky keys”( I don’t remember what tab it is under, sorry.) toggle it on, then toggle it off again. step: 2: enjoy having your internal speakers work again! note: this is how mine got fixed, may not work for everybody.
