compression, gas and spark warrior still wont start

[89warrior1995]

I bought a warrior off one of my freinds the other day and i knew from the start it didnt start, but i checked to make sure it had spark it did but the spark was yellow (so could use a new plug), i took carb off and checked it it was clean and what was dirty i clean, and the jets werent clogged, i cleaned the air filter. I put a little gas in the spark plug hole and it fire for a secong and died right after and one time idle for a few seconds then stalled when given gas,, the bike also has very good compression ,the gas was also changed. any ideas on what is making it not start? thanks in advance

yellow spark is pretty weak you want blue spark. It could be a few things but sounds like she is not getting enough fuel and before you start push the trottle in and out all of the way twice and it will prime the bike

yah im going to get a new plug soon but the carb i took into the auto shop at school and teacher said carb was like new perfect, would it maybe need an adjustment? and was pushing throttle in all the way when trying to start it, could it maybe be the timing off alittle?

no that can't make timing off but you should probaly check your timing
