Tecumseh Carb Needle Valve Install

I have a Craftsman Eager-1 Edger with a 3 HP Tecumseh engine, Model: 143.923511
I have no manual or exploded drawing so I am wondering how you install the needle valve (i think that's what it is) I also need to dig up the proper parts for some that need replacing.

Long story. My dad gave me his old edger since it hadn't been used in 12 years since, the thing was only a couple of years old when he retired it, It's in great shape, practically new. I drained the gas in the tank and knowing my other tecumseh engines thought it would be a good idea to clean the little brass nut in the carb. Well the nut broke in an easy, minimal to no force, 1/2 a turn, so I need to get one of those. The needle valve fell out (again I think that's what this thing is called) Here's a pic of the part I'm talking about: Image

It would be the 'nose' in that picture. The brass piece looks about right too.

I assume the spring part connects into a slot on the float, but I have no clue. When I run my lawnmower down, I'll open that up to take a look for comparison sake, but would love any info anyone might have to share. Pictures, diagrams, comments on how stupid i am, manuals, other sites are all welcome.

thanks

 

If the nut broke, I'd concentrate on getting the broken part out of the carb before going any further, or you may wind up needing to buy another carb. It may be corroded in place and you might not get it out.

 

Thanks for the reply cheese. It came out without a problem

I sprayed it with carb cleaner, let it sit a minute, and it came out with a flathead. The way it broke, I almost think that it might be designed with a weak spot in case this ever happened, it gave me a perfect groove for the flathead.

 

Okay, it broke through the cross-drilled fuel passage which left you with a spot for the screwdriver.

To connect the needle, there is a tab on the float. It goes toward the needle side and the spring clip on the needle just connects over that tab so that when the float drops, it pulls the needle down and lets gas in. It doesn't really fasten to the float in any way.

 

Thanks again for the reply. My float looks like this: Image

So I understand correctly the entire spring will simply slip between the two lower tabs and the one upper?

I was trying that yesterday and had a heck of a time getting it right. I don't know if my spring was bent or connected to the needle properly. Any tips, tricks or tools?

I appreciate your help.

 

One more question, do you know of any source where I can search by my engine number and find the correct parts? The site I was linking the pics from had great pictures, but I cannot find a repair kit for the 3HP engine or one that looks like it has the correct parts. Do you know where I look to find the Carb part number on the carb? maybe that will help me.

Thank you in advance.

 

In that last picture the float is right side up as it would be in the carb. The tab sticking up is what the float clip hooks to. You might view the parts at www.searspartsdirect.com

Thanks for your help cheese I hope these links help someone else down the road.
