for a stock blaster motor if your under 100 psi its time to rebuild

 

I would check compression like they say and also check your carb, you could have dirt clogging your jets.

 

I've read that blasters had problems with the auto lube. Plastic gears getting stripped causing insufficient mixing of oil. That's why you see alot of them with block off's and people pre-mixing. Don't know how old you blaster is or if it's a problem but, something to look at.

 

could the plug be fouled and how hard or how do u clean the carb

 

i highly doubt its the plug. so get off that subject. take off the carb and dip it into some carb cleaner and that should just about do it.

 

1 more question, could it need a new fuel filter?

 

im pretty sure i found the problem, i think it was the carb ring that as loose

 

well i'd stil check your compression just for ***** and grins
