cuts off at idle


Recommended Posts

well it runs strong as hell when your moving and from a stop it does well, but when you make a complete stop and let the motor come down it will kind of sputter and die, and when i restart it after it cuts off, it will sometimes start or require that i pull the choke to get it running and then push it back in and take off.

 

Basically what i am saying is i suck at jetting, so where should i go from here? what would be off?

 

I'm running 330 mains, not sure on pilot or air screw position. Also has t5's on it at sea level

the snorkle is off, and where it goes in an to the back and then into the box, well that part on the inside that makes it a passage way is gone, if that makes sense it just goes in at the inlet and its instantly in the air box

I know what your talking about I still have that passage way in. I have the same problem that it literaly almost dies at idle when you try to give it gas. I think it is just the pilot/ airscrew on my part. It might be the same problem with yours.

tors removal kit, with real idle screws, step 1

if its the stock needle try the 4th clip down and lean out more if need be

leave the pilot stock, and play with the air fuel screws untill its idling good, give 20 seconds or so between adjustments, shouldnt have to turn it more than 2 or so turns out, anymore and ur pilot is too big,,

330's are WAY too big if that thing is stock other than t5's, depends alot on your air filter and airbox setup though, if you got a k&n and adapter in there, cut a huge hold in the top of the box, through both layers,or take the top totally off, and try some 300's which will be rich i bet, and then lean it out from there, depends on the temperature too, its been weird here latley, almsot in the 60;s in day then back to the 30's the next,,that will fuck ur jetting up, keep tjhat in mind

I guess i need to play with the air screws. The 330's feel good as i had 310's in there and it bogged when you stomped on it like it didnt have enough gas and when i put these 330's in, it totally woke up and no bogging anywhere. I guess the tors removal should be the next thing i look at for these stock carbs and playing with the needle settings.

 

Any other suggestions?

if the 330's are good keep them. You have the passage way cut out an I dont so you have more airflow. I am running 300's and it also seems like it is bogging as if it is getting no gas. You said you didnt know what pilots you had right? I'd check it out and adjust the airscrews from there. I bog when you try to punch it when your completely stopped but I think it is the average no torque 2-stroke :biggrin:
