i have a 250 trailblazer that will not start. it ran fine the day before i just moved it into the garage to get it ready for the next day it ran for about 15mins than i shut it off . the next day it fired rite up i put it gear and then i N and it died. i cleaned out the carb,new plug,even tried starting fluid and it wont do nothing. it is getting spark and fuel, i seen alot of talk about a cdi box , what is that?

 

Capacitor discharge ignition. Used on motorcycles starting in the 1950s.

 

ok...............that doesnt help me much.

 

will it turn over at all by the bat.? hows the compression of the motor?

 

if the cdi was gone you would have no spark at all.

 

it turns over with the battery but wont do nothing it doesnt even sound like it wants to start, the comp i havent check yet because i dont have one of those fancy tools to check it yet. even though its a 01 i got it from a older guy he hardly drove it looks brand new would the comp go that soon, i heard that 2 stokes are a pain in th a-- . thank you for taking the time to help me rite now i two atv's down. and its killing me

 

How did you check for fire (pulling the wire, or pulling the plug)? Having spark at the wire doesn't always mean you're in good shape,,, especially with 2 strokes. My dad has a trailblazer & I've got his old 2 stroke 300. He's rarely even makes it to half throttle and rides at a jogging pace. So, he's always complaining about fouling plugs out. I've had his 300 for 2 years and am still on the same plug,,, but I tend to ride a little faster,,, ha ha ha.

Also, the engine could be flooded because of a stuck float,,, another problem that I have had with mine. I reset the float height and have made it a habit to turn the fuel off when I park it. When I have forgotten in the past,,, all I had to do was turn off the fuel and crank it for a while (in short spurts to avoid overheating the starter) and it would eventually fire. Then smoke like he!! for a minute.

 

ya pulled the plug and it looks like it is getting a good spark its a new spark plug, i have not check the float yet i am kind of iffy about the carb this is my first atv and i'm learning as i go. i'll give that a try, thanks!!!!!!!!!!!!

 

Hey do you mix your own oil or does it do it for you i had the same problem on mine all i did was cover the hole and it started rite up

 

DOes it have ETC?
