check the reeds and spark

could be alot of things, does it have good compression, it could be a timing or spark issue. check that you have good spark by pulling the plug, do a compression check if you can

yes, what color is it?

 

[blasterdemon7]

I would check the carb. Your float could be leaking fuel into your motor causing a flooding condition.

Check the frame earths, Blasters are notorious for poor earthing.

 

[bubba813]

so What Do I Do To Test stator If Its Putting Out Enough Power ?

 

[quadboy22p]

are you sure you have fuel, is there a reason your focusing on spark, also what about compression?

 

[bubba813]

Its Gettin Plenty Fuel Thier fuel In The Intake , Thiers spark Its Blue But Some Times I Kick Over Some Times It Dont Spark , Compression I Havent Checked Cause I Dont Got The Stuff Do It With.

cdi box or the main jet in the carb has trash in it

 

[quadboy22p]

how much fuel are you talking about? if you have to much fuel you could be fouling your plug. if you think it is spark check the plug boot, coil and cdi.

Alright Ill Try Thanks For The Help

 

[bubba813]

alright So I did some work to Blaster I Had My Friend Bring His Over To Pull Start It Cause It Wouldnt Start Kicking It , But I Pulled Start It When It Start Its Sputter's & Back Fire's Alot But If I Take It Down Road & Come Back It Clears Up & Thier's Smoke Comming Out Muffler But Not Alot & I Let It Idle For Lil Then Give It Some Gas It Puts Out Alot Smoke Then Clears Up After A Few push's On Throttle. Float Need To Be Adjusted ? Or Foul Plug ?

 

[blasterdemon7]

I would first do a leak down test then check the carb leaking float needl or mis adjusted float.
