So I broke off a carburetor vent hose fixture somehow. The vent hose probably got caught in the chain and ripped off the fixture. Now I was left with a hole where the fixture used to be where dirt could get in. I had to fix this.

I called the local shop and he told me my best bet would be to buy a new carburetor but I said screw that.

Instead, I went to a local hobby shop and bought tubes in successive sizing. I measured the inside diameter of the carburetor vent fixture hole and it came out to be about exactly 2.5 mm. I already knew that carburetor vent hose diameter is a 1/4 inch. So at the hobby shop, I bought 2.5 mm, 3.5 mm, 4.5 mm, 7/32 inch, 1/4 inch, and 9/32 inch brass thinwall tubing, all for about $20 .

I came home and much to my surprise and joy the 2.5 mm tube fit snugly into the carb vent hose fixture hole. I put all of the tubes inside one another, placing each tube 2 millimeters apart, with the smallest tube at the end, creating a pencil effect.I used a large pair of pincers to crimp all the tubes into place, whilst ensuring that I didn't crush the small 2.5 mm tube in the process. Finally I did a couple measurements and cut through all the tubes in one slice with a Dremel tool at the highest speed. I stuck the vent hose onto the fat end and stuck the tiny 2.5 mm tube into the carb hole, making sure it was snug and that I hadn't made the tube long enough to push against anything inside the carb. I then applied a small amount of JB Weld to this area to secure the new fixture. Behold the final product. Unfortunately I didn't think to take any pictures before I applied JB Weld to it, but you get the jist.
