Re: pushing the tickler....
Also check your spark plug gap. .024 to .028 is a good starting point. Too narrow or too wide and it will make starting harder.
We always ask what fuel to oil ratio are you using. Ignore the kit instructions that say 16:1. That's too much oil and that too will make starting more difficult.
