JimmyJam 542 #1 Posted December 26, 2012 I did my weekly fire-up of my 1976 B-80 with a K181s. I recently purchased it: changed oil, new gas, new spark plug. I tweeked the carb adjustments because it was running a bit rough and then noticed red-hot embers (sparks-like) randomly flying out of the muffler (not a stock muffler). What causes that?

Sparky-(Admin) 21,300 #2 Posted December 26, 2012 How long and where was it sitting before you got it? Could a critter (mouse) have deposited stuff like grass/sticks/acorns in the muffler and now your burning it off? Mike.......... Share this post Link to post Share on other sites

JimmyJam 542 #6 Posted December 27, 2012 Thanks guys! I want to restore it back with TLC, but it is my snow plow worker. I know it needs new things: gas lines, gas filter, NOS muffler, etc. Should I put Seafoam in gas tank? Will it help? I religiously fire it up every Saturday and give it several spins around the yard; sometimes twice a week. It fires right up in the first crank, and not much choke. She wants to go!!! Without the plow, I'll bet it'll want to pop wheelies!!!! Share this post Link to post Share on other sites
Duff 206 #7 Posted December 27, 2012 I've found Seafoam to be a very good additive. There are some excellent threads on the forum about it. Cheers! Duff :thumbs: Share this post Link to post Share on other sites
tunahead72 2,400 #8 Posted December 27, 2012 If you're going to use SeaFoam (or any other additive), I would go ahead and replace the fuel lines and add an inline filter first. SeaFoam will loosen dirt and debris in the fuel tank, if you don't have a filter that junk will go straight to the carb and gunk it up. Share this post Link to post Share on other sites
