I guess good things come to those who wait.
I received an email from flea bay listing a part number. What the heck is this? Don't remember anything. In March of 2016 I had set up notifications for some hard to find parts specific to this model one of which were carburetor diaphragms.
In the past I had contacted many Web sites only to be told "rare as hens teeth" and the only place was CMS in the Netherlands. I wasn't about to spend $177.00 each plus shipping but would roll the dice when rebuilding. Pretty easy to change out after a rebuild which is suppose to be tomorrow.
Seller only had two, purchased both for $145.00 shipped out of Germany.
Very fortunate. Good things come to those who wait? It did this time.
