i have a problem with carbon build up on my stil back pack blower can anyone help?
Remove the spark arrestor screen and use Opti-2 2 cycle oil for your mix.
Same problem and fixed it exactly like Bruce said
You may have to take the muffler off to scrape the entire port. It really is easy but you have to be very careful to not touch the piston. Also, I do it so the exhaust port is pointing towards the ground so no carbon goes into the cylinder. One more bit of advice, when reattaching the muffler do NOT overtighten the bolts or else you will have to use helicoils to redrill the holes (no fun at all). Good luck
Just like the other post said you have to use quality mix and remember different gas stations have somewhat different gas.
Remove the spark arrester screen and switch to Amsoil 100:1 premix but, run it at an 80:1 ratio. Your problem will disappear.
All my small engines that are a mix do that. Once in a while, you have to take off the screen, and take a plumbers torch to it. It will burn off the carbon. It only takes a couple of seconds, and then it runs great.
clean port, use amsoil. I mix at 50 to1 2.6 oz per gal.
What brand of oil have you been using?
Yep. Lose the screen. Take it off every piece as soon as you get it and run quality oil. Easy problem to fix.
