Please do not argue with the techs who are trying to help you.
We rebuild these carbs an a daily basis
That is the most commonly used metering diaphragm gasket
So common in fact that Rotary & Oregon both sell them in packs of 10 & 25 so we , the techs can afford to replace then every time we open up a carb.
Just about every workshop that works on small 2 strokes will have boxes of them and some will even have both the diaphragm & gasket kits ( D10WAT) as well as the full rebuild kit ( K10WAT )
When ever a cube carb is opened up the diaphragms & gaskets should be replaced at a minimum for the home owner who is not charging $ 100/hr for labour .
As for buying a $ 20 carb on line can you tell a good one from a defective one ?
Because about 1/2 to 2/3 of what is on line cheap are carbs bought as scrap metal then sold on line as "OEM" or "Fits A " safe in the knowledge that they can never be called to account for this .
That actual gasket is a 92-149 or 92-146-8
Walbro gaskets were by default cut from 1mm thick sheeting
So the original 92-149 is 1 mm thick which was replaced by 92-149-8 which is 0.8mm thick
However for your carb you can also use a 92-359-8 or a 92-359-8 or the 92-251-8 Rivets mentioned as there is nothing to line up with the extra holes .
