I have an ENYA 35X with a TN type carb and a millinium tuned pipe mounted in a Raven 30. I set the two needle's to factory spec's ( main at 2 turns and the low mid range needle at 2 turns as well) with no luck. I realize that the tunned pipe does affect the needle positions could any one tell me if the carb should be adjusted a little more rich or lean? Every few atempts at turning over the engine I have to take out the plug and dump out the fuel so I tryed leaning out the needle's one at a time and alternating still with no luck. I really miss my old OS 32 w/ a standerd muffler on my old shuttle XX it was sooo well behaved.

If your loading up like that, it's definately too rich... First things first, just in case you don't know this... The low-speed needle actually controls the mixture all the way from idle up to about 3/4 throttle. It IS however effected by the high speed needle. If you lean the high speed, you'll also lean the low speed. (In other words, the high speed needle actually affects the ENTIRE range.)

So, with that in mind. I'm assuming your trying to start this at an idle or slightly above idle setting... Set the high speed needle to the factory setting and then turn it in probably 1/4 turn. (I think you said 2 turns out was factory? So start 1 3/4 turns out.) Set the low-speed slightly richer than factory. I think it was two turns too? Then try 2 1/4 turns out...

Next step is to check the plug... You know what... Don't even check the plug... Just replace it.. Make sure your glow ignitor is working good too...

Now try to start her up. If it doesn't want to start after a bit of cranking, then drop the plug, spin it a few times with the starter to clear the fuel, shake the fuel out of the plug, and replace it. Turn ONLY the low-speed needle about 1/4 of a turn and try again...

At SOME POINT it's going to start... Or at least try to start.. Then you know your getting close.... Then slow down to 1/8 turns on the low-speed and get it to the point of idling reliably... Try pinching the fuel line closed for a second at idle. If it speeds up slightly then dies, it's too rich, (the low speed), screw it in an 1/8 and try again... If it just dies, it's too lean. Back it out an 1/8... Once you have it pretty close, let it idle for a minute. If it dies then it's probably still a tad to rich and loading up, try leaning just a bit... If it runs the entire minute, then try adding throttle.. It should have a nice smooth transition.

Once your at this point, you can begin doing power climb-outs to set the high speed. (I'm assuming since you've owned heli's before your not a beginner). Once you have the high-speed set, you low speed will change slightly... Again just set it for a reliable idle. (Always err on the side of rich for both needles).

Thanks Rusirius. I check the plug for glow every other attempt, it is good I also put in a new one and check it as well so the plug is hot. As far as the needle's I have tried leaning the main ( 1-1 3/4 turns) and normal low speed( 2-1 1/2 turns), I have not tried richining the low while leaning the main though. This gives me a glimpse of hope .

I have tryed countless combonations with the needles for days and days some times running down the batt on my transmiter trying to get a pop out of this rig. The closest I have got was a little smoke with a very low sounding rumble, and this was only while the starter motor was turning it over. I wish I had a magic wand that would just pre set the needle's [sm=lol.gif].

I keep posting all these happy face's and the whole time you know I really look like this [&o]. There is one thing that I have learned about this hobby through the years and that is that you must always keep a smile and a good attitude, even thirty seconds after crashing one of your favorite model's. I know I do this more than I like to admit, lol. My uncle who got me in to this hobby was very clear on this in the begining, used to say if you can't laugh about a crash you shouldent even be flying them, which has keep me in the hobby for about 13 years so far.

Sounds like your tank might be siphoning fuel into your engine. Check out the "Uniflow " Tank setup article on www.raptortechnique.com in the info and tips menu.

Your engine should have started by now and should not be constantly flooding.

Yep - can't beat the reliability and user friendliness of the OS32SXH with a good tuned muffler

If you are using muffler pressure be sure that no fuel is at any time is transfering from your fuel tank through the pipes pressure nipple into the tuned pipe. This raw fuel will be immediately drawn into the cyclinder and flodd the engine everytime you turn the engine over and the exhaust port is exposed. This syphoming will happen anytime you hold the heli in a position where the tanks center line is above the pressure line nipple (while transporting the heli, carrying to pit area, or at any time while holding the heli).
