Hello All,
Haven't had my LST for long and it is a new model SN#15xxx. Unfortunately this truck has been a major PITA and I have not had a single day of fun with it since I got it Anyway, I have been trying to get this thing running so it will run with good performance and not overheat (see [link=http://www.rcuniverse.com/forum/m_3111029/tm.htm]previous post[/link] for some background). Anyway, I was still messing with the settings yesterday when I couldn't get my engine to re-start. After about 1 minute I finally decided to check the plug. The little coil in the plug was all bunt up looking and pushed up into the body of the plug. I also see allot of small silver slivers of metal. So I tried another plug, this one failed really fast with the same problem. So I pulled off the heat sink and then the piston sleeve. inside the sleve I found some fairly good sized pices of copper\gold color metal at the top of the sleeve (inside the sleeve) along with more silver shavings. I haven't fully gotten the motor apart yet to see what is broken. Any idea what this is and why it happened? It shouldn't be the washer that I read about because my model is so new it shouldn't have one. I am ready to sell this thing on Ebay and get something else, i have had 3 Traxxas trucks with no problems at all. This was the first non-traxxas truck I ever owned. I have never run more than 1/2 tank before it acts up on me. I really don't want to gove up on this truck because it looks so awsome, but it is really trying my patience.

So question 1, what should I use to properly clean the engine from metal shavings?
2. what parts need replacing?
3. This is a new truck, should I keep this engine or go with a better one? This has been a PITA to tune.
4. What should I use to reseal the engine mounts and sqrews? I removed the engine mount sqrews from the bottom of truck (first time I tried to remove the motor).
5. How in the heck does the exhaust come off the engine?
6. Anything else I need to know while I have this engine apart?

Thank You
