wasp .28 breakin and tuning

[tyrewq]

probably the idle adjustment thingy? to set idle speed of engine? i'm assuming it's like my engine too. the manual said it determines how fast the engine loads up. they like to do 20-30 seconds before loading up.

not sure. i'm new to nitro myself

here are some things i found out:==============

Here are the factory needle settings:

Approximately 4.5 turns from fully closed (tighten all the way then loosen the appropriate number of turns) for the top end needle and 5.5 turns from fully closed for the bottom end needle. Leave the mid-range needle untouched.

I copy / pasted this directly from the instruction sheet. The engine that we have been running here at Team Orion is almost exactly at that setting still. As always settings change due to weather and location, but that should get you back to the starting point!

The factory setting for the mid range is 1/4 turn out from bottomed out.

REMEMBER: It sometimes takes a few days at the track or in the backyard to really find that perfect tune. Most pro level racers often go club racing a few times to get their race engines tuned to where they like it. So be patient and give it some time. Usually when you have good power when the engine is cold but it goes away when it is at full temp. , you are probably to lean. A common mistake is to lean it out when it doesnt have enough power. A Rich settings lets the engine have more fuel in the cylinder which creates more compression, so a rich setting most of the time creates better power. Just tune the high speed needle so it cleans out good and accelerates throughout the RPM range.

I hope that helps.
