[QUOTE="firecracker22, post: 672802, member: 20316"] Ok I have a DT 400 of indeterminate age (it's yellow with a monoshock so I'm told that means it's a 1978) and it puked on Saturday. I inherited it from my little brother, so I have no idea as to its history or its care and feeding. I've been using the same gas and oil as I do for my KTM only mixed at 32:1 as I've been told. It seemed to run strong, though it is very down on power. I am guessing that is just from being long overdue for a top end. It starts very easily, idles, and runs fine (no coughing, backfiring, stuttering, blubbering, etc). Until Saturday that is. I wasn't riding it but when I couldn't hear it behind me for a little while I turned around and poor Keith was kicking and kicking. A new plug didn't help at all, and the plug that came out was a little dark but otherwise looked good--cleaner in fact than the plugs I take out of my KTM. Couldn't kick it or compression start it at all, had to tow it home (now THAT was an interesting procedure!). What do I do? Where do I start? I did pull the cap off and kick it, didn't see a spark. Or do I need to leave the plug in the cap in order for the spark to be visible? I am not sure if it is a gas or electrical problem. Does this bike have points? Where are they? I followed the plug wire but it seemed to go into some kind of black thing, but I wasn't sure when they came out with CDI. It does pee gas which indicates a float problem but I have been chicken to tear the carb apart so far. However this problem came on so suddenly I am not sure it is carb related. This is a spare bike I am taking care of for my little bro, and all I want to do is keep it running. It needs new brakes, seat and cover, and a few other things so I dont' want to spend a whole lot of $ on it, but it was such a stout bike that it has been great for Keith to ride since he is uncomfortable on my bike. (He's just starting--maybe the DT isn't the best beginner bike but it's all I have). Any input will be greatly appreciated! Thanks guys! [/QUOTE]
