Hello,
I recently got a Toro mower with the two stroke Suzuki engine Model# 26682. I had heard these were really good mowers so when I saw one for sale on craigslist for $40 I figured it was a good deal because it seemed to run great.
When I used it for the first time it did run great at first, cutting through tall thick grass like it was nothing. It was after about 20 minutes when I started having problems. At first, the mower would not run very fast at full throttle. I then closed the choke a little bit and it would run better for a while but the engine would surge. Eventually I had to close the choke all the way for it to run and then eventually even on full choke the mower would run, but not very fast, to the point where it was hardly useful.
After doing some research, it seemed like maybe the carburetor gaskets were bad and air was leaking around them, causing a lean mixture from air getting in after the carburetor. So I took the carburetor off, cleaned it (even though it was already pretty much perfectly clean), and cut out 3 new gaskets to replace all of the gaskets between the carburetor and engine. After doing that, the engine fired right up on the first pull and was running better than it had before when it was working.
Well, again after about 20-30 minutes, same problem. The mower would only run with choke and eventually would hardly run at all, and it surged. This was early today and I have not tried it since.
Any ideas on what might be the problem? I don't think its a clogged fuel filter or anything because when I took the fuel hose off of the carburetor, I still had some gas in the tank and it seemed to flow easily out of the tank just from gravity.
Any help would be appreciated, I'm not really sure what it could be at this point.
