Carb to sump Torque Value??

Anyone know the torque value for mounting a MA-4-5 to a 0-360 sump ?

I have been searching and I can not find it.

Got to love the service at Mattituck. 204 inch lbs or 17 foot lbs.

A email to mahlon and 5 minutes later the answer.

Thats service

On "How It's Made" it looks like the guy in the factory used the GOOD'N'TIGHT method to torque these

Yeah, it's pretty much impossible to get a torque wrench on those unless you have a high dollar snap-on job with the interchangeable heads. (I have one, but only a couple of the heads for torquing props... $40+ a head). I just torque them until they are 'tight'. By this time in the build you should have a decent feel for tight enough. Make sure you put in the lock washers!

I had mounted them before but I forget what the torque was. Pulled the carb to get the floats changed. Sent it to Volare. They turned it around in 4 days.
