Reply To: Hard to start when warm

[Don]

Well, your 1977 model does not have one of the redesigned grommets that causes all the issues, so I wouldn’t replace it unless there is an issue.
These engines have a linkage that limits how fast the engine can be run/started in neutral. It is very easy to adjust, there are two screws on the shift linkage that position the limiting bar.
Like Bill says, the choke linkage is often positioned upside down which will cause the choke not to close completely, but you are not having an issue starting the engine cold, so this seems unlikely.
That being said, don’t be afraid to use the choke to restart a warm engine if it doesn’t start after a few yanks with the choke off.
Once restarted, the engine idles and runs OK? If so, seems like the compression is OK, though the readings seem a bit low.
Try testing the compression on your engine when it is cold, before using it, then rechecking after using it to see if there is a difference.
Post some pictures of your engine and carb/shift linkage if you have further questions…
