Anyone skip the 4 impossible to get to nut (under accelerator pump) and only install the other 3 with success ??

 

No.

A bent 12 point wrench is your friend.

 

Is it possible to get to a crows foot wrench on the nut? Check out the offset wrench's in Slow_sevens post on his strut issue, that should help you out with your carb bolt. I had forgotten about these wrenches because I've seldom needed one but they sure come in handy when the need arises.

 

Got all 4 on

 

Used a tiny extendable magnet to place the nut, turned it with my fingers, then used my custom bent wrench

 

I use a phillips screwdriver by placing screwdriver through the nut. and pulling the nut to the top toward the handle. Then placing the point on the stud. Then use my finger to get a thread started. I also use stubby wrenches.

 

Picture of the bent wrench?
