i have read many posts and opinions on this issue of the Honda GCV160 lawn mower engine and the problem of hunting. the original addressee private message box is full so.......
Robert,
I have a question you may be able to help with....
I have a Lawn Boy mower with a Honda engine:
GCV160 {GCV160-S3A-NH1 GJARA 296-1238} with probably less than 48 hours of use at most.
The engine is set up to use an automatic chock release and a constant throttle speed; off/on.
I wanted to check things out prior to using the mower earlier this year. The engine was running fine at the time but I took a look at the spark plug, determined the engine had no spark arrestor, cleaned the air filter element, and took the carburetor off the see what it looked like. However, I was not mindful of the number of gaskets used to re-install each gasket. After finally getting the gaskets and insulator right, the engine ran fine and I ordered some new carb gaskets to have on hand. NOTE: it appears that the carb to insulator gasket was no longer available, and a generic gasket was now being used. I finally found some of the 'original gaskets' and added them to my parts order. (see image of 'original' gaskets) https://www.flickr.com/photos/36268973@N08/
When the new gaskets arrived, I again removed the carb to "add" two carburetor gaskets; one on each side of the air deflector. I saw an exploded view of the system in a Honda engine guide and it indicated the use of the two carb gaskets on both sides of the air deflector, even though the two gaskets where not installed on my engine in the beginning. I put it back together with the two additional gaskets, confident that it would run ok. Unfortunately it did not. The engine now "hunts".
I took it apart again; removed one of the two additional carb gaskets i had added plus the air deflector. It still "hunts". I will put every thing back to the way it was originally, as described above, once I get a new air deflector.
My question is this. The carb itself has a very small orifice on the face of the carb facing the engine, and located directly inline with the mounting bolt. Inside the orifice I can see something brass but I do not know what it is. My question is, did I somehow introduce a small piece of dirt into the R&R process and it has entered that orifice.
Any thoughts.
thank you
