Rob.A.700 306 #1 Posted July 22, 2019 I have a c111 with the 11hp Briggs. It's got a newer fuel pump and carb. I want to cover all bases because recently I ran the tractor out of fuel and since then it hasn't seemed to run right. I run an inline filter but I know it doesn't stop everything. Tonight it ran the worst. It lacked power, backfired, stalled. I have always felt like the governor has never properly worked. I tried adjusting that. I pulled the carb and I am going to clean it at work tomorrow. Is there anything else I should check? May get a new spark plug as well. Any input is greatly appreciated.

troutbum70 857 #2 Posted July 22, 2019 The backfiring part of it sort of seems like points or timing, but also maybe fuel related. Share this post Link to post Share on other sites
ebinmaine 63,079 #3 Posted July 22, 2019 What was the behavior prior to running out of fuel? We run most of our small engines out of fuel ON PURPOSE on a regular basis. I'm thinking a carb clean is the place to start. If you don't know when was the last time the fuel line was replaced do it also. If you use ethanol, definitely replace the fuel line AND clean out the tank AND fuel pump. Once the fuel system is cleaned out, address other causes. Share this post Link to post Share on other sites
Rob.A.700 306 #4 Posted July 22, 2019 (edited) @ebinmaine fuel line and filter are at most 2 years old. Tank was clean. Prior to running out of gas it ran fine with little issue. It just never seemed to have the power it needed. After running out it seemed starved for fuel, running lean the motor was getting hotter than usual. I also run 91 non ethanol in all my carborated equipment. Edited July 22, 2019 by Rob.A.700 1 Share this post Link to post Share on other sites
ebinmaine 63,079 #5 Posted July 22, 2019 Good to hear you don't use ethanol. The bane of our existence in the small engine world and most people don't even realize it. 1 Share this post Link to post Share on other sites
pfrederi 17,143 #6 Posted July 22, 2019 Running hot and lacking power would indicate too lean a mixture. the original carb on your engine had a high speed mixture needle (#118) if the new one does have you tried enriching it. Share this post Link to post Share on other sites
Daddy Don 889 #7 Posted July 22, 2019 Check the points and the setting. Share this post Link to post Share on other sites
Rob.A.700 306 #8 Posted July 23, 2019 Anyone familiar with these engines or have on with a properly set up throttle/governor linkage that can post pictures? It's not easy sorting through 40 years of other peoples "handiwork" Share this post Link to post Share on other sites
