550 Carb adjustment

[PSU Rob]

Does anyone have any information on adjusting the carb on my 550 Industrial? It starts and idles fine for about 3-5 minutes. Once it's warmed up however it will stall if you put pressure on it by using the loader or backhoe. It acts like it is flooding out. Restarting it usually takes a few tries. I haven't rebuilt the carb yet and probably will do so but this piece is new to me so I don't know that much about them. Any help is appreciated. Thanks

You probably do need to rebuild your carb. I was having the same trouble you are having. I rebuilt the carb and my 550 Oliver idles fine and performs fine under load even with a crushed float need to fined a replacement. I wasn't familiar with rebuilding the carb or adjusting the carb and purchased the tune-up dvd for the Oliver and Cockshutt tractors and it gives you step by step instruction on how to rebuild and adjust your carb. DVD is worth the time and money.

Are you sure it is 'flooding out'? I have a 550 Industrial as well and mine was doing the same under load, but it was starving for fuel, not the other way around. Try the choke when it starts to die, if it runs better - that's your problem (in addition to needing a rebuild/clean). A friend was over when it happened to me and he adjusted the dime sized adjuster on the bottom of the carb - opened it up about one-quarter turn. Runs like a new machine. Just a thought.
