Re: I get by with a little help from my friend

Bobby, great stuff! Now if they would only add castor oil to it. We were using the same stuff sixty years ago. The engines would sort of huff and puff and make funny noises. Pop used to tell me to hand him the can of "Startin' Fartin". Ted :)

Re: Seat for Scott Kneisel

Guys, I'm still hoping for someone that's going by here and heading toward Scott Kneisel's place. My health won't allow me to be out and about any more. I'd sure like Scott to have the Cheetah seat. Thanks. Ted Johnson

Re: Airheart Brake Bleeding

Rob, definitely NOT O rings, but also not standard brake cylinder cups. I don't know if Pruit got around to machining his old pistons to accept the available cups. I figured he'd send me a sketch so I could make a CAD model and machining drawing, but so far he hasn't had time. There's no reason w co...

Re: Airheart Brake Bleeding

Hey, Bob, Pruit went through the master cylinder cup thing a few weeks ago. I know he got several that had the right diameter and material, but the wrong shape. I guess he solved it, but it wasn't simple. I think he ended up turning the piston to fit the cups he found. O rings are oh-so much easier!...

Re: Airheart Brake Bleeding

With Tolomatic no longer being interested in the kart systems, they no longer sell the seals for the brakes. You must be able to find which fluid the system originally used so you can keep from mixing them. You might get lucky and find rebuild kits for both master cylinder and caliper so you have kn...

Re: Airheart Brake Bleeding

Good point, Bob! A baking pan beats a pool of red fluid on the shop floor. Even shoving the piston .025 into the caliper can move more fluid than you think! Ted

Re: MCP master cylinder "down arm"

Hi, Larry. I hope your Easter was a good one. I had CAD modeled the down arm for the Airheart for my buddy, Charlie Craibe. We sent them to Waterjet in Albuquerque to make some for him. That made me think I should make them for the MCP. I called Brad to ask him about it, and he told me that they wer...

MCP master cylinder "down arm"

MCP is making a "down arm" for its master cylinders. It means you can turn the master around so the fitting faces the front of the kart. If you clock the fitting on the master and caliper a little, you may now be able to get the master closer to the caliper. Call Brad at MCP. Ted http://www.mcpbrake...

Re: Airheart Brake Bleeding

Alan, it's more stable to use shims the shape of the caliper to ensure the outer half of the caliper can't rock. You can get brass sheet in various thicknesses from a hobby shop. It's easier to cut than steel sheet. Good luck with the feeler gauges. The trick worked on my old 175 caliper on my Bug B...

Re: Airheart Brake Bleeding

Alan, sometimes this works, sometimes not. Take a couple of .025 feeler gauges, loosen the caliper bolts and put the feelers between puck and disc. Tighten the bolts back down. Often, when you take the feelers back out, the disc will be free. Cheap to try! Of course, the best solution is to buy a Wi...
