Okay I got a 1994 ktm 250 EXC last summer the bike ran great all year started first second kick always. This year when I got it out it seemed like it always just wanted to barely start but never would. I took the carb apart it was very clean but I cleaned it anyways and put it back together I also replaced the spark plug with the same plug I ran in it the previous summer I noticed I had a very weak spark compared to my rm 125 u had to Cup ur hands around it to see it at all if u took the cap off and put a screw driver up there and kicked it over it only tingled and didn’t give a good kick like some people say it is supposed to I replaced the plug anyways and it did start and Idled good for a min and then started to bog down I would give it gas and noting and then would rev real high I tried to ride it just around in first gear and the bike bogged down I would give it gas and it would be a full second and then lulch forward then it either died or u was done with it for the night. The next day I lowered the float bowl some since it seemed like it had too much gas but now I feel as though it is the spark not sparking the gas that is in there. I have tried several things the spark plug that is in it is not the manuals one but it ran fine with it last year so I don’t think that is the problem any suggestions I don’t see it very much online with a weak spark it’s always no spark.
