Hi Jim...Welcome to the forum...
Throttle linkage can be a little tricky but not imposable to figure out... Is it a Briggs & Stratton engine?
If you could post a picture or two of what you have to work with, there are several ways to do linkage but they are common on many different applications...
Speaking of pictures... a very handy trick I have used for many years now (since digital photos) take many pictures before and during disassembly ... you may not need them BUT... and come to think of it I have done that before digital, it was not as handy or economical... use to go through a lot of Polaroid instant developing picture cartridges... BOY life is easier now... :smile:KennyV
