I have one too, and that is the way the plug fits, it's acually very secure. I had a problem w/ mine drawing fuel and it was hard to start. turned out the choke plate was off just a small amount and would not close tight. It would not draw fuel up to prime. I just loosened the screw on the plate and repositioned so it would seal, and my problem was solved. You can ck spark by removing the plug and grounding to engine, then w/ switch on, rock the trigger magnet back and forth past sensor. You should see or hear the plug fire. Make sure you have the plug grounded! You can also just grab the wire and rock the crank, Ask me how I know . If you still dont have any luck try www.fpengines.com
