Tecumseh Diaphragm Carb

Greets

I have a small Toro Sno-Blowr that I want to install a new diaphragm in the carb and I can't remember which way I took the old one out
Does the round 1 inch diameter metal plate in the center of the diaphragm face in or out away from the needle valve?

Engine tag # is 7829884 preceded by 1574B

Regards

Hello Fabe317!

The head of the rivet that holds the disk on goes toward the needle. I believe this means the disk goes toward the needle, but it's been quite a while since I messed with one of these carbs.

I'm working on my Toro 2 stroke snowblower carb right now.

My diaphragm has a large disk on the rivet heat side and a small washer on the side that is peened.

The side with the rivet head would go against the needle, thats the one with the large disk

That's what I thought...just hadn't looked at one in a while. The head should be the smooth rounded end of the rivet. It should be on the side with the disk according to Larry , and my vague memory. To post a pic on this site, you have to post your pic elsewhere on the web and link to it on this site.
