Three or four weeks ago I posted that I had left my ignition switch in the "on" position on my Z710A. One or two replied that they had done the same. Well!. that is not good, and here's why.
When I found that I had left the key on, I started the engine and "white/Blue" smoke bellowed out the exhaust for a minute or so. Not good. Didn't think too much of the matter at the time. I connected the Battery Tender to the battery and recharged it.
Today, I went out to start the Z710A and "again" white/blue smoke showed it ugly head. So, I checked the oil, and there Gentlemen came the words...."Not Good" as the oil level show about two quarts over-fil on the dipstick. Results....gasoline. And would you like to know where it came from? I get the Z71-A repair manual out and here's what happens when the key it left on the "on/run position" The voltage is sent to the "engine shutoff solenoid " and it opens to allow fuel to the carburetor. And somehow the gasoline gets past the float-bowl and into the engine.
I remembered that I ran the engine about three or four minutes when the fuel in the crankcase. So, I must change the oil and filter, hoping that I didn't damaged the cylinder walls and all the rod bearing, etc.
However, should it come down to replacing the engine. I'll just snap in a new Kohler ECV730 Command Pro EFI 23 HP 747cc at a cost of about $2000.00. EFI that sounds like a Electronic Fuel Injection dude.
