Would you use this carb slide?

So I've worn out another slide and needle on my BST-40. I'm learning though and have been carrying a spare slide and needles since Quito. Problem is I broke the edge off the top disk in the slide while carrying it in my bag .

I glued it back together with Loctite Superbond and it seems really strong. This part of the slide takes absolutely no load and I am considering using it as it cost me $40 and I am unlikely to find another one until Guatamala. My fear is that vibration will shake it apart and possibly damage the rubber diaphram leaving me dead in the water. The alternative is to run a new needle in the old slide which has an ovalized hole. Besides the poorer fuel mileage and performance I think I will wear out the new needle quicker.

You can see the repaired slide below. Opinions?

a cv carb is hardly worth putting any but very little money into

most motors are much happier with a flat slide

i think you will be fine for now but i would probably think about ordering a new one and then using this one as your back-up.

laters,

I don't know what kind of force that part of the slide experiences... creeper knows that kind of information than anyone else I've come across 'round'bouts'chere.

It may be a stretch, but if the old slide is good save for the elongated hole, is there any chance of being able to epoxy the "slot" closed and re-drill it to the proper hole size. If you are careful, I'd think it could make for a usable slide. Maybe. Just throwing WAG's here.

As for the cracked slide, that repaired flange nests into the diaphragm. I would worry about air leakage causing the diaphragm to not function properly, but the bike should run. I'd use it in a pinch. I'd also put it back into my "back-up parts" bag when the new one arrived.

As Meaty said, hope for the "Big C" to stop by and give you his thoughts on the matter.

That's where it sits at the moment. Put a new needle into the old slide and it runs "OK" at the moment. I'll run it this way until I get a new slide or it starts running worse.
