Seal the air pan to the scoop opening.

Leave the exhaust. Faster through muffs is better

Add jet until it slows down and go back down a size.

Does your 3310 have a secondary metering block? If not convert it.

If you add one step in jets and it slows down, go the other way until it slows down.

Once you find the optimum fuel curve, start experimenting with timing.

Get a log book and maintain copious notes. Change ONE thing at a time.

I PROMISE YOU, if the motor is remotely healthy you have a solid high 12 second ride with the parts that you already have!

Happy Hunting!
