Thanks, Bert. I was lucky to get an OEM carburetor for my roughly 15 year-old Toro 20038 mower for $41. The chinese/after market carbs were running anywhere from $10 (this carb didn't fit) up to about $30. So, at $41 for an OEM replacement this seems reasonable. I could have used the original...

Hey guys, just wanted to come back and thank everyone for your help. It turns out it was the carb, after all. After I rebuilt it, the mower ran pretty close to perfect. But, I sensed a small amount of surging and figured if I got the float positioned right things would be fine. Well, after I...

Thanks for the bread tie tip! That's a great idea. I appreciate the tip on the shellac too. You are absolutely right about the carb cleaner and how it behaves. The first time I sprayed the carb cleaner on the carb it splattered all over the place - including my face and eyes! It's a miracle...

Thanks. Throttle plate - got it! I seem to have 2 welch plugs. When disassembling the carb the first time, one just fell out on its own. I didn't remove the other one because it appeared stuck in there. There's a little groove/hole on the side that I tried to pry up - but I didn't want to use...

Thanks. What's strange is that the float wasn't parallel the first time I opened the carb (bowl). Regarding the red seat, I really pressed down firmly with the end of an allen wrench with the same diameter as the seat "washer". Did this twice. Any harder and I was going to break something.

Thanks, Slomo. I'm not good knowing the technical parts yet, but you know when you look into the carb and there is a brass disc that's bigger than a dime yet smaller than a nickel, and it rotates? There's a tube running through that (top to bottom - or bottom to top). I'll look into this when I...

Thanks, guys. I was sure to clean the carb really well; including every small hole I could find. Used carburetor cleaner, very thin needles, air pressure spray, etc. One thing that I wanted to do was remove the emulsion tube. However, I was unsuccessful with that. Does anyone know how to remove...

Got it, thanks! I installed the rebuilt carb a short time ago and it started on the second pull. However, I can still hear the up and down revving somewhat. Could this be another issue? If you have a moment you can watch the 10 second before and after videos. Before...

Thanks. I did install the red seat with the grooved side in first, away from view. It has a grooved right around the perimeter of it. What does chamfered hole mean?

Hi guys. I'm in the middle of my rebuild but have come across a problem I'd like to run by you. I'm having a hard time getting the carb float to rest parallel to the carb. I replaced the red "seat" and made sure it was down all the way (used the butt end of an allen wrench to firmly press down...

Thanks Bert. I appreciate this. I'll be sure to come back and let you know how it goes.

Hi guys. Thanks for all your help. The Carb rebuild kit arrived today for my lawnmower. Toro Model 20038 (Briggs and Stratton engine Model 122602-0111-E1). I'm having a hard time finding rebuild directions. I visited the link Bert sent but its hard pin-pointing which instructions pertain to the...

Awesome, thanks Slomo. I appreciate these steps you outlined. Also, thanks for pointing out that this mower is a keeper. This is good to hear.

Thanks, Slomo. I'll start with the carburetor first, and maybe move on to the other maintenance. I'm glad to hear this mower is a keeper. I'll take of it for sure.

Thanks, Bert. I appreciate your help and for providing the outdoor power info link. Personally, I'd go straight for the rebuild. However, I have a relative that wants to install a new, non-OEM product. I'll wait until this $10 new carb bombs and then do the rebuild :-)

Thanks, Bert. I visited the site but when I searched for my Toro model number (20038) it didn't yield any results. From what I understand, it has a Briggs & Stratton engine. I'm wondering if I should check the engine for its own model number. I'm a few miles away from the mower location so I...

Thanks, Mark. I'll look into carburetor rebuild kits and cleaning methods. I appreciate your help.

Hi folks. My lawnmower revs up and down when try to use it. I think this might be called, "hunting and surging". The mower is about 10-15 years old. I made a 10-second video and I'm hoping someone can view it and offer possible solutions. Video Link...
