I know you will like it. The needles on this engine are a little tricky at first but no biggee. If you have a problem let me know I might be able to help, Or better yet call Ralph.

RTK,

Can you explain more about your comment: "The needles on this engine are a little tricky at first but no biggee."

Chuck

According to the instructions Ralph sent he ran it and set the needles. Hopefully I won't have to mess with it.

Hank, I haven't had any issues with adjusting the needles at all on these engines. You'll be ok... it ain't nuttin but a thang. Where is Granite Bay?

The only thing to watch out for is that the HIGH needle will affect the LOW if you do not have the butterfly closed enough. This can cause adjustment headaches. I know believe me.
Follow this procedure and you will not have any problems

Set the High for peak and back off a couple of hundred rpms.
Set the low for good transition and good idle (keep leaning till it won't transition then richen till it will)
NOW REPEAT THE ABOVE PROCEDURE and you are set to go. Remember Low will affect High that is why you repeat.
This is the same basic procedure to use on any gas engine. Ask Ralph for more details if you neeed.

Pull out the idle screw, there is no need for it anyway. If you get all turned around set both needles at 2 turns and repeat procedure. It should idle about 1800 give or take.

Try this on a few different engines a few dozen times and nothing to do with needles will every give you a problem again in your life.

I run all the conversions...My settings at 7000 feet will be leaner than someone who lives at sea level..I DO NOT advocate running an engine without setting the carb.."Factory" settings are only an educated guess that sometimes come out right and should NOT be left as is, on any new engine..

I'm not particularly worried setting the needles. The trick to setting a gas carb seems to be to take your time and be patient. Once set you hardly have to touch them.

Thanks Ralph, I will adjust before I fly. Don't want to ruin a new engine.

Good advice RTK, thanks.

Granite Bay is by Folsom lake, between the lake and Roseville. Just outside Sacramento.

You can't possibly ruin the engine adjusting the needles..If it's wrong the engine won't run right and you will hopefully not try to take off...If you lean out the high speed needle on the ground the engine will just quit from lack of fuel before it runs long enough to hurt anything..These are not ABC cylinder glow engines...

Good to know, thanks.

You could open both needles about 1/4 turn from wherever I had them set, should be very close...do the high first....
