[Tom hadlow]

I have a bg86 that run fine when in an upright position but as soon as you change the orientation of the blower it will stole out I have pressure vacuum check it and all is fine I have also checked the whole fuel System (fuel line filter tank breather) and pressure test the carb I am really stumped in what could be the cause of the problem any help is much appreciated thanks tom

Maybe a damaged insulation on the short circuit wire grounding it? Also check the high tension cable for the spark plug for damages.

mine was running wierd and it ended up being the spark arrester in the muffler being blocked with oil residue. I unscrewed the arrester and burned off the buildup and she runs like new.
