i have an older XL gasser with a G23 engine. running gas and 3 oz. of amsoil. while spooling up around mid stick the engine sags or quites. i don't want to start chasing needles. can anyone suggest which needle i should start with and rich or lean.

Hi
The first thing I would suggest is to check and clean your filter
I had a similar problem it would start and idle fine and as you spooled up it would sag then quit
its unlikely that the needles will need radical adjusting if its been ok previously
when I opened my filter I found a great wad of muck
hope this helps
Cheers Michael

I agree that you should check the filter and other things first. Once a gasser is set rarely should you have to do anything with your needles.

cleaner was a wrong term to use. i have a velocity stack. guess he was talking about the foam air filter. not using one. as i spool up and the heli gets light on its skids it sags or quites, but if you can get past that it flies fine.

Hi Torque
I was actually meaning the Fuel filter
However if you say it sags then comes good at higher throttle setting this would indicate a lean idle mixture?
What carby are you useing? if its the 677 then this unfortunatley may be Normal they really suck on the heli engines

i am at work, so i can't check the carb #, but i think it is 197. the heli is smoking so i really don't think the engine is lean. the last time i pulled the plug it was perfect.

3 oz.'s of amsoil may be a bit much unless you are breaking it in. try dropping it down to 2 oz.'s (this is per gallon i presume)

agree.
go back to 2 and the richen the needles a litte. let us know how you turn out. A lean low end will also do what you describe and actually kill it when it is too lean spooling up.


but if you say you have smoke and the engine is running 'ok' I think it might be just the extra oil in the mix you see. Somewhere this a fine line of needle and oil mix with xyz carb. Let us know know what happens.

It coiuld be the screen inside the carb, There is a small screen on the inlet side of the carb,, you will have to remove the bottom plate, to get to it,, I have had this happen before.. But first I would try to richen the low needle just a hair,, Hope this helps.. John Crotts

Whoa there horsey! If you haven't flown it since November and it was running fine then, carb adjustments should be minimal and other things need to be looked at first, primarily your fuel system. That much "down" time between flights may have resulted in fuel evaporation in the system and oil and other matter having congealed enough to stop up your fuel filters. Personally, I would pull the fuel system apart, replace fuel lines and clunk line, then pull your carb and do a through inspection and cleaning. Replace/clean all your fuel filters. That's where I would start, were I you.

Could be this!
Hello,
One other thing you could check, make sure that your lower frame, the two running down either side, are not cracked anywhere. My gasser had one side of the frame cracked, and when I went to approach hover, the frame would actually open up, and the engine would sag, but, as soon as I brought the throttle back, the frame would close up tight. It took me a few minutes of cursing, adjusting needles to no avail. All of a sudden I went to pick up my heli, so I could look at the bottom of the carb, and I noticed "from the bottom" that my frame had a crack. Soon as I replaced the frame, my heli was as good as ever. This is the extreme, and I hope it's not your problem!!!
