please post what altitude,humidity and temp also ;)

Got to B&B at noon of Fri. Used heat gun to cycle engine to 250'F. Let cool down. Heated again to 250' and started with VP Racing break in fuel. Used Thunder Innovation heater and idled 1 tank. Kept temp at 200'F. Let cool. Repeated 2nd tank. Let cool. Heated again and started. Blimped throttle on and off entire tank with TI heater still on. Let cool. Heated again. Started and richened high needle 1 turn, opened full throttle so wheels were spinning slowly while I held a heat gun to block to keep it at 190'+ for entire tank. Let cool. Heated and started again and drove in street 1 tank with VP 25% fuel and put on race tune. Let cool. Heated 1 more time and put it on the track. Fine tuned each tank with no heat gun needed. Ended with these settings:
Idle .7mm
Mid range 2 turns out from flush at 2 o'clock
Low 1 turn in from flush at 2 o'clock
High 1 and 3/4 out from all the way in

7mm reducer
Temp 265'f

Humid, mid 80's
2060 pipe
P3 plug

Engine ran perfect and had almost half a tank after 5 min quals. Never flamed once and idled like a kitten. ;)

Also I did not use the break in shim. Temp was about 280 for the first 4 tanks on the track, then it broke in and cooled to 240, so I leaned it out more.

Can you run this engine in a truggy?

ive been running this engine in both buggy and truggy for a year now with great success

Thanks, how about matching pipe for a truggy

i use a werks 2013 on both

Stock factory carb settings?

Use these carb settings. The factory settings do not work.

Agree.....:nod:

I will try it out...

thanks

I set everyones arrow carbs at the track last weekend the same as mine and they all loved it.

the setting is almost identical in every engine.....consistent, ease of tuning and reliability.

Got my new Arrow engine in yesterday, looks good, although this thing is SUPER tight, couldn't even really turn it over by hand with the flywheel on, are they all like this? Guess once I start the break in and heat up the head it will be easier to turn over and start? Lookin forward to see how she runs!

Why would you try to turn it over by hand?? :weird: Every new engine is like this. Keep the engine out of the pinch zone until you are ready to start it. Heat it to 200 degrees before attempting to start....
