My first JD lawn tractor was a 110-8 hp. Kohler. My FIL's friend was a JD salesman and sold me the first JD. He said the engines were made to run wide open. He said he always left the throttle wide open till he was shutting it off. He would idle down, shut it off, and put the throttle back at full for the next start. Since then I've had Kohler 8, 10, and 12 hp. My JD 318 I bought brand new was an Onan, the JD 265 I have now is a Kawaski 17 hp, the walk behin is a 20 hp Kawasiki and I start them all on full throttle. They are al electric start and fire on the first bump of the key. So, if the choke is on the same lever as the throttle, I put it on choke, and as soon as it fires back to full throttle. The wood splitter is a no choke Briggs with a primer bulb. Pump 6 times and it always starts on the 2-3 pull. last year I had a hard time starting it, turned out it had water in the fuel.
I was at an auction and bought a brand new, in box, Briggs Ready Start for $25. It says it's guaranteed to start on the 2nd pull every time or the will fix it free.
