How does it run after you get it started? Is it getting a good spark? Whats the compression?

[cing31fan]

Run's like a shamp,it can get on it quickly thats why im stumped. Im going 2 get a new plug monday 2 see if it helps, but it seems to be alright, it does'nt look like lighting fire under someonce @$#@.HA,LOL. compression,well seems ok just have'nt road it in a long time so I just thought it was being cold blooded,but after I road it around for about 5 min and killed it it would'nt kick start. Well if this helps I have 2 keep the RPM's up 2 keep it running but the carb has'nt been adjusted,its from another CR and its not pluged or anything..

[Rickster]

If the carb you just put on has sat for a while, there is a good chance you have one, or more of your jets plugged up.

I haven't had a CR carb appart, but most carbs have 3 jets. A main jet, a needle jet, and a pilot jet.

From your description, in this case, I would start with the pilot jet. they are really small, and almost impossible to clean, and they are cheep, just get a new one.

The other thing that comes to mind, is you might need to adjust your float level.

[cing31fan]

cool Ya all sounds good place to start with. I plow the carb before I went 2 use it but still should sheck the floats.Now that I think about it the spark was'nt that all impressive to me. If this helps at all after several kicks and I get the puff of smoke it sounded like a car that was out of time, however I know that they are 2 different vehicles..could the spark be weak enough to just let it puff like that, and just for a nother apinion do you think the spark should look strong if you now what I meen?

[bigE]

if it runs good after it gets started i would change the plug and go through the carb again like rickster said

[Rickster]

cing31fan Just a friendly hint. I don't want to sound like your english teacher, but you really need to proof read your posts, before you hit that reply button.

sorry about the spelling been thinking about a lot of thing's past few day's. However plug didn't do a damn thing. Starting to think compression isn't as good as I thought. Just tryed to kick start and it seems to be to easy to do. More of a consistent movement and not a lot of pressure being built inside. Have spent about 18 years working on cars but not a much on bikes in a long,long time. Question is there any were I can get spec for compression ect. online like a car or due I have to go get a book? Guess what? found a web site it's 9.1:1 Site is Bikez.com..

TO MUCH GAS clean carb and a ring is cheap an easy ron

[cing31fan]

? Motor was just rebuilt last year..That's kind of why I'm stumped..

[the_privateer]

9:1.1 is the compression ratio, thats not what the actual compression is gonna look like when you test it. it should be around 160 psi for a 125 of that age, but the test vary a lot-so if you get anything over 120psi i'd look at the carb.

First thing is to set the float. this is pretty much the best explanation ever given here

it possible that the petcock is leaking gas into the carb when in the off position causing the bike to flood, easy to check just remove the fuel line from the carb while the gas is turned off and see if its leaking. it doesn't happen a lot but it did happen to me

if its bogging at low rpms and won't hold an idle you need a smaller pilot jet, if its bogging in the middle range you need to raise the needle clip

what bike did you get the carb from?

[cing31fan]

Thanks for that, You read my mind I was trying to turn that 9:1.1 into psi. I was told it was off the same year 125, however looked at it yesterday and it looks more like a 250. Its bogging at low rpms have to keep them up. but haven't played or adjusted the Idle yet. My original carb was stolen along with few other things while I was out of town some time ago. Guess they needed it a hole lot more then I did. I had a good idea the a_ _ hole was and took care of the pest problem. If I cant pay for afford it guess I don't need it.
It only bog's down once Im down to a Idle, any further up then its fine no mid range bog just all power.

[the_privateer]

once you've set your float, play with the airscrew some and see if it has an affect. if it doesn't do anything, or if you must take it more than 2.5 turns out from all the way in, you need a smaller pilot jet.

[Rickster]

Some years back, I had one I couldn't figure out. Went through all the usual steps, spark, gas , air, turned out the trouble was a restriction in my exhaust. If the bike has sat for a while, check for a mouse nest in the exhaust.

[cing31fan]

Whats Up? Haven't been here in a few days, but I just went and ordered a new carb. Should be here in a couple of days. That is a good place to look in my exhaust never thought about that. You guys are all great glad that I ran into this site it ROCKS. Check back soon..

[cing31fan]

What's Up? Well got the carb adjusted it and everything and still doing the same thing time think it is time to replace the rings for some reason.. After I pull start it wont kickstart still. I only road it couple of times before I bought it to make sure it ran but now it wont run the way it is suppose to. Starting to think the friend I got it from is full of it on the rebuild. We have so much snow that its hard to really work on it, because I have a 1976 Dodge that is pushing close to 400 hp and a 12" lift. Its my "pride and joy", hoping to post some pictures when its done. My wife thinks Im going to berry my self with it when I die. Im doing the body work on in the shop. It runs but dont want to pull it out. So waiting for snow to melt. Its been nice past few days so Ive been trying to figure it out. But think it needs new rings.? So what do you fine people think about that ? True or what.

Cingular31fan and your friend...

What year is your bike? I'm just wondering if it's one of the real old air cooled models, or if it's water cooled. Either way, it's not a real big job to ring a 2-stroke, but defiantly less work, if it's air cooled.

[cing31fan]

Rickster its a 1991 water cooled. I haven't had water cooled bikes apart before, only air. But that was 15 years ago. But have had 3 or 4 air cooled motors apart and true not hard; however never this year of a bike. Its in awesome shape with very few hours on it from what wear is visible. Just seems to me some people dont appreciate or take care of the things they have. Riding and Hunting are the only things my two boys and I have left that they still want to do with there dad. 16 and 11.

[Rickster]

Wish I could help more, but I'm pretty much out of ideas. It just doesn't make since that it would run good after you push start it, and than not be able to kick start it. Are you sure you have a good strong spark? The sparkplug should show blue at the electrode.

[cing31fan]

Well I think its OK not the strongest spark Ive seen. It's a brand new plug and when I hold it to check it I fill OK about the spark if you are understanding what I'm trying to say about the spark..Do You think I should change the coil or is that what you call it. I do know this about the spark. I have to pull the kill switch wires to get spark if the are connected the right way the plug wont spark until I pull them back apart.But Yes it runs like a champ after its running. It has all the power in the world thats why Im so stumped..
