Thanks for the heads-up, Rusty. I'll try to check my Black Widows over the holidays. This could be why I had a flame-out and had to land inverted on asphalt!

I pulled the old topic out of the trash. I'm going to merge these two topics...

You seriously need to stop adding Viagra to your fuel

My bagel almost fell out of my mouth after I read that! Watch your mouth...

I have taken a very thin piece of piano wire, and ran it right up the tube ans spring, it holds the bend...

Being a comsumate do it yourselfer, while there were no cox rescources available I did this:

When the old solid as a rock pick up tube needed replaced I trimmed off just the portion of the tube that was necked up for the nipple. a short piece of silicon fuel line sleeved over the end of the old pick up line, put onto the nipple;done and with the righr shape I might add lol Beer Cheers

And I havn`t had to replace 1 of those yet Hand Shake

Brilliant idea.
Well it does... but I'll use less colorful descriptions.

Cool, that's brilliant too. I hope that wasn't my last one I chopped up to get the spring out of.

Yet another good idea, thanks Mud.
I'm filling the place with all sorts of questions tonight.

If the length is correct, it will not necessarily be curved, but have a slight "U" shape instead. This worked pretty well for me.

Been doing that one for awhile now. I also cut the pickup end at a slight angle so the end of the tubing cant butt up against the back plate and seal off. Once I have it right, I disassemble and lay it out and cut copies/spares for other motors.
