Mike harris 5 #1 Posted February 1, 2019 So my 10 hp on my b100 wants to backfire and quit under load(snowblowing). If I run it just under full throttle it will run ok. I have 2 thoughts. 1. Governor 2. Fuel pump. Just a thought. Does anyone have any ideas? Share this post Link to post Share on other sites
gwest_ca-(File Mod) 11,492 #2 Posted February 1, 2019 Have seen a spark plug cause that and a bad condenser. Easy to try one at a time. Garry 3 Share this post Link to post Share on other sites
Mike harris 5 #3 Posted February 1, 2019 I did read that after I had posted. I will start with the plug. Thank you for the response. 1 Share this post Link to post Share on other sites
