Thank you for reading.. I have a 1978 Kawasaki KL250 when i try to kick start it the thing won't do anything.. But if you spray fuel into the carb it will start but won't stay runnig on its own.. You have to kepp twisting the throttle very quickly to keep it going.. Once you let off on the throttle it stalls.. Things i've checked.. I do have spark but it's orange i think it might be like that because i'm not running a battary.. Compression 4 to 5 kicks i have 125psi.. Carb i pulled apart cleaned out and the needle and seat from inlet side will hold 6" of vaccum.. I'm hopeing someone can get me in the right direction on what to check for next or had a similar problem.. Thank you, Willus
