Carburetor Tube Broken
Hi Guy's,
Finally found time to start work on the 49 Cub. I have been working on the list of things that are recommended when you bring a Cub home. Because the tractor sat for five years I wanted to rebuild the carb.
When I open it up I gently separated the body halves and found the tube that should have been hanging down from the Idle valve area broken off and loose. It appears to have separated at the end of the threaded portion. I have a "Complete Carb Kit" coming from Steiner and went back to look at the picture and it appears that a replacement tube is included with the kit.
I plan to soak the broken of portion with penetrant, and attempt to use an E-Z- out to remove the broken off portion. Failing that I will drill it asn retap to opening for the new tube.
Any Suggestions?
I am attempting to pose an image to clarify the components.
Thank You,
Dick Cupka

Re: Carburetor Tube Broken
If you have any small left hand drill bits I'd try them first. Don't use a drill, but do it by hand. The idle tube threads are 4-48 and that takes a # 42 drill bit, so you'll need to start smaller. The EZ-out may expand the soft brass and make it harder to remove.

Use a 3/32 left hand drill bit.

Re: Carburetor Tube Broken
Soak that idle tube stub in your favorite penetrant (not WD40) before trying any removal technique.

LH drill bits are available at Harbor Freight. I bought a small set with case for about $15.

Thank You for the advise, sounds like you have been down this road before! I'll pickup a left handed bit tomorrow and let you know how it comes out (no pun intended).

Why not WD-40?

Re: Carburetor Tube Broken
WD-40 is not a penetrant. It is a Water Displacing lubricant. I have not found it to be very effective when used as a penetrant. Your results may vary.

Yep! BTDT. I got lucky with a small ezyout and it backed out after soaking for a while. You might not be so lucky, that's why Bob recommended the LH bit and hand drill, less chance of further damage and difficulty removing the pieces. A broken ezyout is a SUPER PITA!!!!! BTDT TOO!!!!! Once is enough.

Make sure you use a hand drill and not a power drill.
There are two ways to get enough Cubs. One is to continue to accumulate more and more. The other is to desire less.

When I see a post that says not to do something then I assume damage will occur. In this case that WD40 will somehow damage the potmetal or ZAMAK of the carburetor. I don't think anything in WD40 will damage ZAMAK.
The original name of WD40 does not have anything to do with what it can be used for. All penetrating oils are water displacing, that is what a thin low viscosity oil will do. A penetrating oil is just a thin low visosity oil and WD40 certainly meets that definition.
I typically will not give my personal preferences simply because there are too many variables, at least with using penetrating oils, that a personal preference is essentially meaningless. I use about 1-2 spray cans of penetrating oil a week, many different brands including WD40. I have not noticed any differences with any of them, just too many variables for a human to sort out through their observations.

Re: Carburetor Tube Broken
Success!
I soaked the tube and casting in PB blaster, used a drill bit and then an easy-out and it came out clean. I will post a picture tomorrow.
Thanks for all the advice

Re: Carburetor Tube Broken
It feels good to have that accomplishment under your belt. Now, your replacement tube from Steiners will go right in.

Re: Carburetor Tube Broken
Threads came out cleanly. The Complete Carb Kit from Steiner Tractor arrived yesterday and all the parts look great. Hope to put it all together this weekend and if all goes well will attempt a start for the first time in 5 years this weekend.
