I hadn't started my MF 135 Perkins Gas 3 Cylinder for several months. A few weeks ago I started it up and it was backfiring really bad, popping all over the place. I was able to rev the engine at that time, so I revved it up and after a few minutes the pops and backfires stopped and I was able to start mowing down the fields with my rotary cutter. I mowed for probably 1.5 hours without an issue.
The next day I got back on the tractor to continue to mow and it started right up and backfired for maybe 30 seconds and then was fine. I mowed for about 15 minutes and all of a sudden the tractor died. I tried starting the tractor and it was backfiring all over the place again and I couldn't get it to rev at all. Eventually it got so bad, I couldn't even get the tractor to start anymore.
I took the carb off and thoroughly cleaned everything, put it back on today and I can start the tractor and it will idle for a while, but if you try to rev the engine (give it gas) it backfires all over the place. At this point I can't even get the tractor to move as it dies if you try to put it in gear.
I currently have the mixture screw all the way out, which will let it idle.
I am pretty much at a lost and no really a great mechanic, so what are my options at this point? Part of me wants to go buy a new carb and see if I can just call it a day, but at $400 that isn't a cheap option.
Here are a few videos that show the issues.
Thanks for the help!
