10-20 carburetor suction tube replacement????

Dave Koenigsfeld · Apr 14, 2011

I have restored two 10-20s which are posted heavily on this site. I have one nagging issue. My carbs will always have a little drip so I try and tighten up the acorn nut just one more little lb of torque and snap! It breaks off. The suction tubes are always the most rusty and weakest piece. I own 5 carbs and only have two functioning carbs and not extra suction tubes.

I have ordered new suction tubes from the Fordson House. The 5/16" parts fits the lower half of the carb fine. However, it is too small to connect to the upper part the carb and hold all three pieces together.

This has to be somewhat of a common problem. What is everybody using when the ole suction tube snaps????

This is the only weak spot in my two restorations and I don't want to keep buying carbs on ebay in hopes that the suction tube is good.

As always........thanks for all your help.

One I have had the suction tube broken near the bottom. I used a 3/8" UNF x 1.25" bolt. Through drilled (long ways)with small bit. Then used a mig welder to afix it to the long (upper part) of the broken tube. Ground smooth. I must have drilled a cross hole, but forget the real configuration.

This worked. I now have a lathe that I would fab a new one - may still have to weld to the old stub.

May have a spare if you need one. Won't be back until July though.

ok, well the suction tube from Fordson House works just fine.........i was playing around with it this weekend and took a wrench and a vice grips and waalla, the tube just spins out of the upper nut. Insert new tube and it is back to new!

Had to repost this in case someone else does a search on this topic.
