It looks like from this picture that our two carbs are identical. Which round gasket worked for you?

If you look at the pictures in post # 26 and look at the third picture down from the top it looks like he used the bottom gasket in that picture.

If you look at the first picture in that post I am assuming that is a picture of your carb and gasket.    See how that gasket has a diagonal opening.
The gasket in the bottom of the third picture has a straight opening.    That is the gasket you need.

My pic on bottom I use bottom left one which matches one on right coming out. One I think I always used in all of them.

Your pic would be the top and one at top  shown  in pic.

Thanks Cut4fun, Thought that's what you meant, but wanted to be certain.  Thanks for all of the information. Hopefully I can tackle it again this afternoon.

Thanks 3000 FPS, that's what I though he was saying but just wanted to make sure. Sometimes I have to be hit over the head.

Can tell I was tired. In your pic above top one was like the one I used.

So I got it back together and she fired right up! Made a video but   too big a file size to post. Learned a lot here: Had to fix a leaking fuel connector, prevented fuel from being picked up. Had to replace check valve, self inflicted problem because I put the carb in carb cleaner. Should have gotten a Walbro kit from the start, one of the diaphrams in the after market kit was reversed. When I had someone work on it they put the wrong round gasket under the plate for the needle valve, so I didn't know which gasket belonged there. I really appreciate the help I got from 3000FPS and especially from Cut4fun. Probably wouldn't have figured it out otherwise.  Still interested in buying one of these carbs as a backup if you have one to spare someday Cut4fun? Thanks guys

Had to go back in and lower that fulcrum height just a smidgen.  Even using the Walbro tool I thought I might haven been just a hair off.

What was the symptom that told you you had to lower the fulcrum?
