If you’re good at welding thin aluminum, yes. Then you’ll have to very carefully clean up the weld on the reed surface.
If the cages are "trapped" in the reed manifold by the carb gasket and faceplate and the reeds are intact, why bother with the crack repair? The gasket will block leakage in the cage provided the reeds are working OK. If the cracking got to the outside reed opening, the cage is toast.Quote:

Yes. If a piece breaks off and goes through the motor... $$$$$. :nonod:Quote:

I saw 5 petals for $6 but most 7 petal I’ve seen are $100. Is there a lower price somewhere?Quote:

7 petal horizontal reeds were a rarity nearly 20 years ago. $100 price for a cage sounds about right. I'm sure there is an aftermarket cage you can buy that is near that price. The 7 petal front end manifolds are even harder to find.Quote:

If you contact them might just sell you one or two.
Personally I’d buy the set of six.

You can still get the replacement five petal version of the seven petal from Mercury at $300 each.
thats why I’m thinking about trying to make a 7 petal front half out of a 5 petal. I can’t find anything about doing it.Quote:

Key problem is you need the reeds to seal with a gasket to the reed plate and the front half is a whole other animal. Whatever you do to open the cavity for the seven petal it must be done carefully because that’s the other half of the crankshaft mounting which also has to seal the crank rings too. Lots of places to go wrong and it will take a lot of time. Probably why no one has bothered
