Golden Bees from the Sturbridge trip...
roddie Tue Dec 26, 2017 3:02 pm
These two engines share a peculiar "damage" between them. Both of them have damage to the bottom tank-vent. 
I don't know their history. They were included in a bag of 10 "used" .049 engines.. mostly Cox.. but also a couple of Testors/McCoy rotary-valve engines.
One of the GB's had it's tank mounted 90 degrees from normal.. and the other had a Tee Dee glowhead installed..
Both engines have #2 cylinders.. and the "standard" (Babe Bee size) air-intake.
Well.. I'd been wanting to further-inspect these engines ever since sourcing them.. so I took them apart this afternoon. What I found; surprised me a bit..
That engine doesn't look like it's ever seen a drop of fuel..
Here's the other one.. not quite as clean.. but a LOT cleaner than I would have expected.
These engines both show "external" signs of being run. The gold anodizing is worn-off where the starter-spring contacts the nose of the crankcase.. and there are the tell-tale "scratches" of mounting-screws on the tank-anodizing.
One has a "tight-spot" in its cylinder-bore. I'll have to see if I can lap it out. It seems to be above the exhaust-ports though..

If the vent tube is loose in the tank, some carefully applied J-B Weld should cure it. I did that on a Black Widow some years back and it held pretty well. I've found J-B Weld to be glow fuel-proof and have also used it to attach clunk weights to brass tubes in my 1oz fuel tanks.

Vent tubes can be pushed back out of the tanks and replaced. You can make vent tubes by sanding down a section of aluminum tubing. They wouldn’t be gold anodized though.

As long as they don’t cause a tank leak they will work fine as is. Not knowing the history, the front ends could be used, tanks could have been cleaned out, new rebuild kits installed and new backplates. Looks like some sealer was used on the gaskets so they have been apart at one time. The possibilities are endless.

Roddie, I'm glad to see that you're better! ... I'll tell you a solution that I do in these cases.
I take a spoke from a bicycle wheel, I adjust it well, I hit it by inserting it into the tube and the aluminum tube expands, then I extract the bicycle beam.
I give temperature to the aluminum tank with heat gun, and I incerto the expanded tube, when the tank cools it compresses the modified tube! Chau leaks! Solved theme friend!

Thanks friend!!
It is advisable to place some fat in the bicycle beam, so that it is easier to extract later.
Placing a washer between the beam and the tube, then allows us to use the washer to retain the tube, without having to force the tube and deform it accidentally, it works, it really works!

That's a very interesting method/fix Mauricio! Thank You for sharing!

Mauricio, thank you!!
I do have an 8cc tank that leaks, and I thought sealing it from the
inside was my only solution. The technique you posted is pure genius.
I also have access to liquid nitrogen, perhaps to shrink the vent/fill tubes.
A new year hug for you!!

Great idea on expanding the vent tubes Mauricio! 
If you make a new thread on how-to tighten/seal the vent tubes, I'll make it a sticky. Or, this thread can be retitled.
