Hi. I just developed a problem today with the 23 V Twin Kawi on my Lazer HP.
I was trying to catch up after a week of rain so I'm running doubles and taking down some tall grass as well as mulching leaves, so the engine was working pretty hard. Then I noticed that the engine sounded different, louder.
It's been a while since I've changed the plugs and air filter and I was close to home, so I ran home for lunch and did that. The engine is running well, starts as well as it ever has, accelerates without hesitation and doesn't sputter, stall, run uneven or anything like that. The problem is, that it's loud as heck. Sounds like it's just got a straight pipe on it...it actually sounds good, but the exhaust has kind of a throaty rap to it, like when you suddenly load an engine hard and the governor kicks in. I checked and there's no exhaust leaks that I can find and the noise is coming out of the tailpipe. And, it's going through fuel really fast. I know the doubles and hard work will make it thirsty, but I went through over 2/3 of a tank in a little over an hour on my last lawn. I've never seen it use that much fuel.
I have a feeling the governor is stuck wide open. The problem is, with all the back bumper stuff and all, I can't even find it. I've never even seen the carb on this machine, which is a good thing, except I've never thought to lubricate anything since I've never had a problem.
So where is the governor? Right side as you look at the engine from the back? Left side? I don't even really know how a governor works although I have messed with them on push mowers and it's usually the spring. Will running it like this cause any damage? I can use the WB instead if necessary.
Any other ideas?
Thanks,
Darryl
