Where to find Carb part for Tecumseh AV520?

3 posts in this topic

I read a couple posts on adjusting the Carb on a Tecumseh AV520 3HP because mine would not run right. Went out to adjust the Low and high speed adjustment screws and noticed that my high-speed adjustment screw is missing. No wonder it doesn't run right! Does anyone know where I could order a new one? Or would most small engine places have one? Not sure if they are fairly universal or not.

Thanks!

That is the model of the engine. There aren't any engine manufactures that make carbs, so when you need a carb part you get the model number and make off the carb.

I think yours would be the Walbro WT-257.

You should be able to get that from a small engine shop or do an on-line search with your carbs make(Walbro) and model(WT-257).

Best bet it to go to Walbro's site and do a look up your carb model. In fact I've done that and your High speed needle is part # 102-3096-1 At that same site you'll find a list of shops to order that part from. Or call a small engine shop and tell them you want part # 102-3096-1 for a Walbro carb.

      Has anyone heard of a giant walleye caught on the Saturday of opener?  Sounds like the boat called the DNR and they rushed right out to take pictures, etc. Not sure if it was close to the record or not, but I heard it was a giant.

      Was up at Long Point with 5 guys last Thursday PM through Sunday AM. Thursday evening after the wind went down a bit the fishing was great. Ended up getting our limit for the 6 of us that evening. Ate fish that night. Friday and Saturday were slower but still pretty good. A LOT of little ones so we had to sort through them to get some keeper fish. Ended up getting our limits to take home by Saturday afternoon and then the rain started. Very few slot fish, which was a bit of a surprise. Only 4 over 19.5", with 2 at 20, one 22 and the biggest being 25. Jig and a frozen shiner/fathead worked well. No real preference between the two minnows. Jig color didn't seem to matter that much but we had best luck on gold, pink, chartreuse and glow white. Depths we fished were 21-26 feet, pretty much all those depths worked fine. Really fun trip and I look forward to the next one.

      Here's a couple pictures of one of the 14' boats I redid, a 25hp will be plenty of motor for a 12' boat.  The14' bat in the pictures with the additional weight from the wood would go 26mph with just me in the boat.  As you can se  left the compartment open for the gas tank, so I could monitor the level and so I could breathe better. Send me a message if you have questions.  It's really a fun project to work on these old boats.

      Do you have any pics of the process or finished product by any chance?

      wow, this is exactly what I was looking for. Unfortunately idk what the hell i'm doing, as I have no carpentry skills LOL, but i have a buddy that builds houses, so I am sure he would have the necessary skills and tools to assist me. It cant be too hard, right!? haha. Anyways, I appreciate the information, this is GREAT. Ill be sure to touch base with you if I have any questions. Thanks again!! I have a 25 hp motor right now...really old, a chrysler 25 HP from like...the 70s or 80s. You thank that'll be enough power with the added weight?

          You can keep one Walleye 13.8- 17.7 a day. With the conservation licence you can take 2 fish out with only one over 27.6. and with a sportsman licences you can take out 4 with only one over 27.6.
