Hey guys, need one of these badly- seems NLA everywhere and obsolete is a word thats being tossed around alot. If it's obsolete, doesnt that mean they've replaced it with a newer design? its for an 81 merc 25(2cyl 2 strk). Any help would be greatly appreciated. Thanks
Matt

Have you checked ebay for a complete replacement carb? sometimes the only way to get parts is to buy the whole carb and take what you need off of it.

i havent done that yet, hadnt thought of it actually. I'll see what I can find, but i was ordering a repair kit for my carb and just wanted to replace the jet- to be sure my 25 frankenmerc isnt actually an 18 wearing a 25 cowling. Thanks. Still hoping for the jet though, but if i can find a decent carb i'll get it- its an 81 though. are chances good of finding my carb?

There should be some on eBay. When i looked for one for my motor (1979 Merc 402 40hp) there were 4 or 5 for sale ranging from 30-80 bucks. They all looked to be in good condition.
