Hey Guys,
Just got my rebuilt engine put back together, and mounted. Started right up, but at low RPM or idle it tends to backfire a lot out of the exhaust. At higher RPM it sounds fine, and every so often a little backfire. What could be the issue?
The carb was rebuilt with a kit, and triple checked timing marks before putting the engine back together. I used a air gun for the flywheel wheel, so I believe that's all good and tight. I used a business card to gap the Magneto, so I think that is good. Plug is new. Gap is .003 for the intake, and .005 for the exhaust.
I'm not sure if the mixture screw is off or not. I started 1 1/2 turns out if I turn it counterclockwise the engine will speed up, and slow down clockwise.
Here is the Youtube link to the video I took of it running in case it helps. (Apologize for it being a little shaky.) Briggs & Stratton Rough Idle & Backfire - YouTube
Appreciate any help and advice.
