I am messing with a Briggs 375 on a mower, Drill starting it is fine, (takes a few revolutions to get it to fire) It runs nicely, no rattles or smoke it is just that I can't get enough revolutions out of it on the pull start to get it going. I was going to scrap it but it runs fine once started. Any thoughts? I have changed the coil and that made no difference and neither did swapping the plugs around. I'm guessing maybe a valve problem as this motor has been sitting around for many years. I'm thinking that if I use it to mow my lawns the valve problem may seat itself down properly? I wanted to try that today but we keep getting this rain
