A right pain to replace on certified aircraft with the single airbox in the way!
It's a right pain to replace, even with dual K&N air filters, too. Access is tight, to say the least.

As I recall I had to cut down some box wrenches to access the nuts and bolt heads. When I made the replacement I increased the distance of the holes from the edge and slotted them. Slots allow for minor misalignment without stressing the bracket. My guess is they crack due to minor misalignment.

And when you do replace this bracket......be sure to place a cloth under the bracket work area so that an errant nut or washer doesn't fall into the magneto/generator assembly and its voracious magnets. No, this didn't happen to me but the potential for a major headache is great.

I've observed the same on mine. Part #33 on this diagram.

851-267 BRACKET

I know my plane was getting uneven throttle at full rpms, the throttle cable on the left carb was jamming against the fuel line hose, not applying full throttle.

Very, very time consuming to get in there to change this part out. Removed the K&N right air filter for easier access to the bits that needed un threading. Miserable in there, if you have large hands.

Temporarily, I've wedged and glued some hot water insulation foam around the engine mount and between the ignition coil. Will address the problem when it's a bit cooler, both temperature wise, and frustration wise, dealing with fixing this right. In my case, I'm sure the cause was the throttle cable on the left carb not going to full throttle, while the right hand side did. It was jamming into the heat proof fuel line.

Rotated the heat proof fuel line away from the throttle linkage, and resecured with zip ties. Now I get full throttle from both carbs.
