muz123 1,192 #1 Posted March 22, 2015 (edited) This morning i went to go start it up for some seat time then a bunch of mouse nest stuff came out of the exhaust. So i sprayed out the carb and all of the little holes. Started it again and it does the same thing, but when i take the air filter off with the cover it runs flawless and when i put it back on with the cover it sputters and backfires and no adjustment will fix it. Any help? Thanks, Dave Edited March 24, 2015 by muz123 Share this post Link to post Share on other sites
muz123 1,192 #2 Posted March 24, 2015 I think it might be the breather inside the engine, gotta take it apart and see if it's clean or has any cracks in it. If it has any cracks i have to buy a new one. dave... Share this post Link to post Share on other sites
gwest_ca-(File Mod) 11,510 #3 Posted March 24, 2015 Sounds like the air filter is restricted. I know engine oil on the filter media will cause the condition you describe. Garry Share this post Link to post Share on other sites
muz123 1,192 #4 Posted March 24, 2015 (edited) Thanks, but there is nothing on the air filter. It is very clean. Edited March 24, 2015 by muz123 Share this post Link to post Share on other sites
