Spray first time without retard?

Just curious if i should have the ignition not pull any timing out the first time i spray it. Or if i should just pull the recommended 2* for every 50hp rule.

Some people say that they dont have to pull any timing for a 100-125 shot.

So what would you recommend?

I don't pull timing on the 150 shot and I have had no problems. As long as you have colder plugs and run premium fuel, you should be ok.
