husqvarna hu700f with Honda Engine- ENGINE PROBLEM

[overheadstew]

Hello everyone-

I am new to this forum so bear with me. I have a husqvarna lawn mower that is giving me some engine problems. At the start of the season, my lawn mower would start, but would rev very slowly and had a hard time before it would die. I cleaned out the carb and it seemed to work well for a while. Then I noticed that the engine would start fine, but then it would surge and have a hard time finding a steady rev while I was cutting my grass. It got to the point where it wouldn't fill up the bag and struggled through thick grass.

After starting the lawn mower, I could press on the governor throttle arm and after a few pushes it seemed to run a more consistent rev. My governor arm on my honda engine has a small hole and a large hole. One day I moved the spring position to the larger hole and it revved fine and gave me no troubles. My question to everyone is- is this ok? Do I risk harm to the engine? Should I get a new spring and put it back back into the original position?

Thanks again- I know this a lot, but it has been killing me since this lawnmower is only 1 year old.

So it probably is still under warranty, I'm sure. In many cases, the engine and mower chassis have their own warranties, as they are made by different companies.

I would contact your local Husky dealer and inquire about having the mower evaluated and inspected. Worse case is they tell you there's bad fuel in there, and charge you to replace the carburetor. Or, you may also have a Honda Engine dealer check it; find one in your area by using this link:

The real problem is not the governor spring location, but most likely stale fuel in the carburetor, or a malfunctioning choke system. Honda issued a Service Bulletin on certain GCV160 engines with Autochoke; if that is the real problem, it will usually be repaired at no charge, but confirm with the dealer what is and what is NOT covered before you authorize any repairs.

Only a batch of the GCV160 engine might have an autochoke problem, and you can find out if your is part of that batch. Get a flashlight and look on the side of the engine block for the engine serial number; here are the ones that might have a defective autochoke:

GJAPA-1000001 through GJAPA-2295257
GJAPA-1546575 through GJAPA-2295257
