How would you fix this?

Briggs 3.5hp horizontal shaft 091202-1231 E1-0105293A

Need a good way to remount the carb to engine block.

Heavy object knocked off the air filter housing, carb and fuel tank from engine block. 2 pics show the engine block and broken area. Has 1 good bolt hole at the top of carb mount area.
Tried low temp aluminum repair rods from harbor freight. Can't get enough heat into the aluminum block. Didn't work for me.

My ideas are below.

1.JB Weld carb to block using 1 good bolt hole.
2.Same as above using a paper carb gasket.

Question is how would you fix this?




Dotted rectangle area is the part that is broken off the block casting. Thanks in advance guys.

can you put a heli coil in the bottom hole?

Half or slightly more of the bottom hole is gone.

Other than taking it to a welding shop and have it TIG welded...... Probably cost more than it's worth.

Thinking about using JB Weld or a good fuel rated RTV sillycone. Basically gluing the carb to the engine block. Use the only good top bolt to gently hold the carb to the engine. Don't want to crank the torque on it as to make it sit off the engine slightly. Just as a backup so to say.

What do you guys think?

Could you tap the good portion of the hole, install a stud, then carb, then a nut.. Use the RTV as well so it won't have an intake leak..?

If you can get a drill to run square into the hole
Drill & tap for a solid insert and install it so it is just lower than the original surface
Build up the broken bit with what ever liquid mets / putty type goop you like. let it set then sand to a smooth flat surface.
And I woud do as Scrubby suggested and use a stud on the bad side.

Or if I could fit a small C-clamp or Visegrips LOL. The tank has a bolt to hold it on. Carb sits on tank.

What would McGyver do?

Here's some pics of the block area where the carb mounts.

Is it possible to find a carburetor that uses the two remaining tapped holes?

I hope I can explain this correctly, if that area is flat behind where that bolt goes thru could you make a plate that would fit behind where it is broken and tap a hole in the plate than use a longer bolt to go thru the broken area and thread into the replacement plate. You would have to make sure the plate would fit well enough to not shit when you tighten the bolt but once tightened it should stay put. Looking again you could also slip the broken piece between the the carb and your new plate to fill the space.
