which i am a hour away from right now.

do you guys just lean your hsn first? or both? should i not even touch the lsn now? what kind of tunning steps do you take?
be careful doing that. One time a friend broke a head off(all but bottom fin) in a race and temps were aroung 45 and that thing went hot fast.

What is your outside temps?>

My email is alanburton20@gmail.com if I can help you in any way.
dreaux, maybe you should send the engine to Alan for
a proper break-in. Leave the carb needles where you
have them set now, box it up and send it to him, along
with your phone number. I'm sure he would gladly let
you know how far off you were on the adjustment and
give you some pointers. Please don't give up on burning
nitro and turn your car into a flashlight. Most of the guys
that offer engine service and modding would gladly help
you with getting your engine right. They all love to talk
about these nitro belching little engines. Good luck.

outside temps were mid sixty's. i need to tune it up obviously. the plug was soaking wet when i took it out.

Besides if i don't get it right now then it's ruined any way, like some of the other motors i have had. I good break in is great and all but if it's not tuned right it won't matter. A bad tune will destroy pinch regardless.

now i am going to tune my high end and get it close to full power. My problems come when i try to lean my high and low at the same time.

Will my idle raise if i lean out the hsn??? It's very fat right now and i don't want to mess with the lsn until i get the hsn right. At the same time, it wont idle with out me setting the trim to keep the throttle open it's too rich, but i don't want to lean out the low end just to get a better idle right?

I think you just have a bad temp gun..try cleaning it, or going with exergen..Do a test, Boil water and temp it with your gun, it should be at 202-210 degrees

During break in....I really only mess with the LSN for the most part. At least for the first few heat cycles. I'm not revving the engine anyway....so the LSN is doing the brunt of the work.

Just send to Alan...he'll get it spot on for ya ;-)

105 degrees Celsius = 221 degrees Fahrenheit, which is about right for an engine that is quarter turn rich than a race tune.

switch your temp gun from C to F!

My Alpha plus S852 still has alot of pinch after over a gallon of fuel. Don't worry about the pinch.

Stick with it fella, you'll get there.

I heat cycle....but I like the sounds of this when getting started...didn't think to keep the gun on it for a tank or two of rich idling...thoughts?
