Not sure how that can happen sleeves can only go down in the case one was the case has a pin in it and the sleeve has a notch in it where it lines up in the case

We are running the long needle. Cody likes the smoother lean mid range with the long needle.

Thanks got them on order who knows when they will get in stock on another note idle scree broke again dont understand why this happens first time thought was setup wrong got everything perfect and it has happened again oh well

Anybody know the best way to fix a nipple? Just took the 2058 out of my king worlds motor combo and the nipple was welded so close to the pipe the fuel tube wouldn't go on there and I pushed and pushed and could not get it to go on so I heated the pipe up really good to try and bend the nipple out some and as soon as I tried to ease it out it snapped right off

You can drill and tap it and screw one of these into it.. http://www.amainhobbies.com/product_...ssure-Nipple-4 Use JB Weld when you screw it in..

Just tried to help a friend start breaking in his alpha motor and could not get it to run. Upon close observation, we found the needles to be unscrewed all the way as this is how it came from the factory.I assume they vacum set the carb before it gets packaged. This seemed very odd so we put them back to the factory settings before attempting to start it. We then got the motor to fire but was not running correctly. We immediately shut the engine off and pulled the pipe to find the sleeve had been turned 90 degrees. I did not catch this when we installed the head shim since neither of us were sure where the alignment marks were supposed to be on the sleeve. Has anybody else run into this before?

Normally this happens if you turn up the idle when the slide is closed. Try to pull the throttle open a little when you turn in the idle screw. This should prevent any problems.

Is this a Team Orion Alpha line engine? Or the Alpha engine from Taiwan? Sounds odd, never heard of it. The sleeve is keyed so it would be really tough for the factory to install it wrong and install the head. Did you turn it back to the right position and run it?

Orion alpha line, We did turn it back and run it and it ran fine. When we pulled the head off to install the break in shim, I notice one of the screws was way to tight. Once I loosened the opposite screw the first was much easier to loosen. The bottom of the sleeve had one imprint from the pin and the pin had been pushed in the block almost to much but just enough to catch the sleeve. As I stated it was odd the it was turned exactly 90 degrees. Just never ran into this before and I am not an alpha guy so i did not know any better.

sorry guys, there won't be any blue head Orion engine.. he was just running that to test the configuration. The new cut we will have, but the color will be red.

The needle and button set will work on the JTP, as the configuration of King/Tebo are the same. This button and needle are simply an option which gives the engine better tuning and power for American style tracks. That engine was originally run at that ginormous Pattaya track and bottom end smooth response wasn't too important, just power :lol:..

Ok, what is the difference? Head button volume? Is the needle just a finer thread count?

Thanks.

Slightly different combustion chamber. The needle is long and gives more linear mid range feel.

I see, a low speed needle..... I was thinking high speed at first. Makes much more since. Sounds like it should take care of any rich mid-3/4 throttle symptoms. Sign me up :nod:

My 5 port Discovery button just has the 3 dots on it. I take it this is the old head button?

Edit: nm, found a pic. ;)

Should allow for a slightly colder plug, for better run times, and no mid bog.. I'll prolly pic up the head and needle set as well..

Looking to get an Orion 3 port. I here of good and bad things about these motors can someone explain thanks

It would help to know what you have heard.

I here that they only last for a couple of gallons and they don't idle that good bt I really want to try one I see them running and seem to run really good

6 gallons seem to be typical, from my stand point, but that is all I have ever really gotten out of any engine.. I have had 1 of my 2 Discovery motors need a front bearing at the 2 gallon mark, but it seems to be exception rather then the rule.. As far as Idle goes I have had no problems with that at all. If you tune it correctly, IE what the engine wants, not what you might think it needs it'll idle all day. One thing about the Orion Alpha engines I have noticed is they like a hotter plug.

Is there a long needle and head button available for the .24 CRF's I am running ?

How do you guys feel about putting the newer carb on the the engines that came with older carbs? I have the .24 with old carb and a new b5, the .24 before this had n old carb n SUCKED so I put on an old style os carb from my .30 n it worked good. Now that I'm getting back into it I have the new lm carb but worry it won't be set right.
