CSB80 3 #1 Posted 5 hours ago Just purchased this from my neighbor. Always wanted one since I was a kid, and seeing my grandpa with older tractors. Came with a plow, and mower deck. Neighbor said it hadn't ran in 3 years. Changed fuel, oil, and transmission oil, new spark and fired right up. Did just recently clean the carb. Only issue I'm having is, it seems like it's surging. Any ideas? Thank you all. Wanting to tear it apart this winter and restore it. 3 Share this post Link to post Share on other sites
SylvanLakeWH 32,362 #2 Posted 4 hours ago I just picked up a B-80 myself! Great little tractor! Did everything you did as well. Had to soak the carb 3 times before it ran. Change entire fuel line, filter, and the fuel shut off / rubber grommet at tank. Clean out the gas tank - a couple times... Replace the whole petcock / grommet etc. Old fuel line will keep feeding the carb a steady stream of gunk... Also, adjust the governor. Surging went away for me when I did that. 2 Share this post Link to post Share on other sites
ineedanother 2,850 #3 Posted 3 hours ago Excellent! Post the model and spec # for the tractor and engine. Download manuals from this site and look through them. Verify that the governor is adjusted correctly and focus on the fuel system to stop the surging. Other advice will be coming... 1 Share this post Link to post Share on other sites
