lobo 22 #1 Posted January 19, 2015 I have recently did a rebuild on my 16hsp, it busted the rod and chipped the bottom of the cylinder so I used a different block, have cleaned the carb several times and here's the problem, now it will idle fine for a few minutes but then wants to rev up, not much but some, if I reach up and push the linkage closed it idles fine for a few minutes then revs up again, I'm thinking governor gear? Don't really want to tear it down again, but hey. Looking for any input. Thanks Share this post Link to post Share on other sites
rmaynard 14,922 #2 Posted January 19, 2015 Do you have the throttle/governor linkage hooked up correctly and did you adjust the governor as instructed in the manual? Share this post Link to post Share on other sites
lobo 22 #3 Posted January 19, 2015 Yes, have readjusted everything several times, carb, governor linkage, and the timing. Share this post Link to post Share on other sites
rmaynard 14,922 #4 Posted January 19, 2015 When you have the linkage loose, how much can you rotate the cross-shaft? Share this post Link to post Share on other sites
lobo 22 #5 Posted January 20, 2015 Hello, I went out and checked the rotation and there's not much, less than a 1/4 of a turn. Share this post Link to post Share on other sites
lobo 22 #6 Posted January 22, 2015 How much is the governor shaft suppose to turn when everything is loose? Share this post Link to post Share on other sites
rmaynard 14,922 #7 Posted January 23, 2015 Less than 1/4 turn. I would go back and readjust the governor again according to the directions in the manual. Share this post Link to post Share on other sites
Shynon 7,435 #8 Posted January 23, 2015 How much play is there in the carburetor shaft? If you have movement, wiggle it while running and see if it changes. Tom Share this post Link to post Share on other sites
