JimD 3,345 #1 Posted September 23, 2013 All summer I've been battling the carbs on the B60 and B80. They ran rough and only ran with about half the choke applied. I tried adjusting them a few times to no avail. They'd run ok for a bit then back to rough. Well the other day I bought a new battery for the B60 and when I put it in I decided it was now or never getting them straightened out. So I set the adjustment screws to bottom out counting the turns on both tractors, took them out, cleaned them, shot some Gumout carb cleaner in the holes and let it soak a few minutes then blew them out with air. I reset the screws to manual specs like I did earlier this summer on the first go-round. Then it occurred to me to tighten the mounting bolts. They weren't loose, but they did turn a bit. I think they were just loose enough t suck air and cause the problem I had. They ran beautifully when we mowed this afternoon. So when you get into carb issues, take a second and check the bolts and even periodically again to keep them snugged up. Made a huge difference on mine. 3 Share this post Link to post Share on other sites
