Re: Cold motor start
Hard starts aren't a plug problem! They're mostly a carb problem.
Stick with the #6 plug.
The trick to starting a hard to start engine is just finding that "sweet spot" on the choke!!! It's usually around 2/3 - 3/4 of the way closed.
Also, beefing up your ignition system will help! (better wire & boot, & solder the CDI wires)
One more thing... too much oil can cause plug fouling (& hard starts). Use regular 2 cycle oil mixed 24:1 for the first two gallons, then switch to 32:1 after that.
