Awaking my TD .09

TDbandit Tue Feb 10, 2015 11:18 am

Today is somewhat decent so I decided to give my TD 09 a little exercise and man I forgot how loud it was It's been years since I've run it. Anyway here's a couple of pic, one sitting in wait and the next burning some nitro Smile

Here it is popping off that nitro. Kills that syringe in 45 sec lol I'll have a video of it running as soon as I figure out why it began surging all of a sudden after the pic was taken. (Bandit)

(Edit) Well I found what was causing the surging, After looking the engine over I noticed that the dang plastic carb body had split at the threaded portion just under the NV block. DAMMIT!

The split goes down past the threads on the venturi so it had developed a mean air leak. To be honest I'm really suprized that it kept running, bummer and it don't look like Bernie or Matt has one. Anyone know where I can lay my hands on one??

I have a couple of them and never fired them up. Never seen one run in real life either. I think I'll give it a try this weekend. One of them has some slight contact at bdc between the piston skirt and the backplate. I don't know why, but will investigate.

Skirt interference with the back plate?? Haven't seen that yet Could it be something down in the case? (Bandit)

I don't know. I took it apart and inspected all the parts, it all looked okay, so I put it back together. It still did it so I chucked it into a drawer for another da...year. Now you got me interested so I'll dig it out and have another look. And run the other one. They're both nice looking engines that were given to me. I bet it's a slightly bent rod that I didn't notice the first time. Somebody might have hydrolocked it and slammed it with a starter.

That is very possible and if it is indeed a bent rod, check the crank too. I've seen them crack around the pin when slammed with a starter while hydra-locked. (Bandit)

I have seen the piston hit the backplate on a well used Queen Bee.
As the piston wears against the conrod and is reset, it will sit lower and lower in the bore....

Matter of fact come to think of it, I had that happen with one of my well used BW's which ended up punching a hole in the top of the piston. That there is a possibility as well.

BTW, Do anyone know where I can get a new carb body? the surging I experienced was caused by a split which runs down below the threaded portion of the venturi and I've looked on both Matt's site as well as Bernie's and I didn't see one. (Bandit)

I'll look for that, Thanks Kris.

If you can't find one you can sleeve the neck with a piece of aluminum tube and JB-Weld. If it goes beneath the neck I don't know if you can seal it up with JB or not. Maybe spreading it slightly and forcing the glue into the crack.

If you can't find aluminum tubing you can also use copper wire. You might need to "rough up" the nylon with sand paper to make the JB-Weld stick. Ugly but works.

Thanks I didn't think of that. I'm still hunting for a plastic body hopefully i'll find one. I'll try the aluminum sleeve method you mention if I can't. You'll enjoy running the 09 BTW just watch the finger's It can be a biter lol. (Bandit)

Mike Parkin can provide you with a aluminum body for the .09. He may not have them listed currently on Ebay. Cost is going to be more than the stock plastic. Mike's name on Ebay is Ridenfligh. If interested in that route I would certainly check with him. Ken
