NormK now you admit it. I had thought you were in the dark during my daylight hours here.
Bonnar, What you are looking for is the GX110, GX140 service manual but I haven't seen any PDFs available just paperbacks from Honda. They don't even have a shop manual though they are worthless anyway. Honda does keep a tight reins on their service manuals which is probably why there no PDFs out there. They are still in the dark ages on this. I rather have the PDFs as they much easier keep track of and definitely not grease covered.
What worst Honda doesn't have any available currently according to their Amazon store here.
So if someone has one they could scan the page or pages related to the governor linkages and springs and post them for us to look at. It would be nice, otherwise someone could just take a snapshot of an actual engine's governor setup and post it. I would but I have not even seen a GX140 here in the 9 years I have been working on the Honda engines.
