I recently installed a new bearing, brass spacers, and brake pads on my turbo bumblebee and the response is excellent.
However, I only get a few seconds of spin before it runs out of steam. Is this normal after installing a new bearing, brass spacers, and brake pads? What should I do to get a longer spin time?
I think that is probably the issue. I cleaned out the old adhesive before replacing it and was able to press the pads down. I have a brand new OEM bumblebee string but replaced it with a generic white sting and it is working better. Spin time is around 7 seconds which is okay but I still think I have an issue with the pads.
It almost appears that the pads would be making contact with the bearing, hard to tell without seeing it installed. If thats the case, you could either snip the tips of the pads that touch the bearing or like Ben said, use it a bunch and wear down the pads a bit.
Maybe the lube was came on the bearing/spacers is the issue?
I think this is probably the issue. I would try cleaning the bearing in your solvent of choice (I use 99% iso alcohol, you can also use mineral spirits, zippo fluid etc.) and putting on a new drop of thick lube. I would try ruling out the bearing as the problem though before worrying about anything else.
