Hey all i just bought this engine second hand. The H.S. needle came removed from the carb. Can anyone give me some ballpark needle settings to get me running?

TIA

raddivr, the instructions for mine say 1.5 turns...That should be close, but you might want to go a little more, just to be sure it's a little rich when you first get it going,especially if it's new.

thanks. Ill give it a try tomorrow. Still have linkages and stuff to adjust tonight.

No Go proptop.
I can get it to start if i prime the carb and suck in fuel. It starts, it runs that fuel out, wont suck anymore in, then dies.
I have both needles Low speed, (left faceing front of plane) completly open. I have the highspeed needle (right facing front of plane) out 5 turns and still cant get it to stay running.

Suggestions?

Will it draw fuel when you choke it? Put your finger over the carb. opening(plug batt. not attached) and turn the prop thru to see if there is an obstruction somewhere in the line or tank...It should pull fuel thru the line when you choke off all air! Especially w/ the needles that far open! Sounds to me like you've got a kinked fuel line, a blockage, or a split fuel line or something like that...Check all your lines, the clunk(make sure it's to the back of the tank) and maybe reverse flush the carb. Seeing as you've got the needles so far out(man) why don't you take your fuel filler line and push some fuel thru the spraybar.(take both needles out, of course) I'll get right back to you w/ the rec. setting for the idle needle, if you need it...Tom.

It will draw fuel when choked. I pulled the tank out thinking it was some other draw problem, like the outlet not being above the carb or something. Still no go. Ill try cleaning the carb and see if that helps. Denatured alcohol for this?
and the idle needle setting would be great if it doesnt mess you up at all.

No prob. The spec sheet says 1.2mm (.050") out from the nut, or the distance between the idle needles outer portion that screws over the threads, to the retaining nut...But that can vary a little. If you need it I can check the actual # of turns mine is out, but, if you've got feeler gages, just measure .050" out after turning it all the way in. And yeah, alcohol will work fine...If you can, use a fuel bulb, or just hook up a length of fuel line and blow thru it to see if there's any crud in there. Are you using muffler pressure? That helps a lot, and some engines won't run w/o it! What plane is it in? Is the tank center-line about level w/ the needle valve? What about the plug? Sometimes the most obvious problems are the ones that get over-looked. Got a good starting batt.? I hope this helps cuz I'm runnin out of things, ya know?! Maybe someone else will "chime in" and notice something else we missed...
