Answer to "Why won’t my car run after cleaning the engine?"Take air filter out and check if it's soaked with water. After that just let that thing dry out. Or replace air filter. I buried a 93prelude in water and blew the motor. A little water won't kill it but a lot can seize they engine or cause rods to shear.
Answer to "Why is my rescue 900 jump starter not charging"If you don't keep those things fully charged at all times they won't take a charge after a while. Also if you don't fully charge it before first use it can really hurt the internal battery. Hope that helps. I'm in same predicament with mine.
Answer to "Mower's Rpm dies when deck and collector is engaged"Sounds like a mixture problem on the carb or over tightened belt. Might be running too rich or lean. I'd check belt tension. Air filter, mixture screws if present, then proper spark plugs gap. Adjusting mixture may or may not be possible with that model.
