If you closed the regulator this is the wrong direction. You made it leaner. Surging on the mid range, requires you to open the regulator further.

This is is the pressurized YS system. The regulator adjustment directions are not the same as the Dingo engines. The DZ enigne don't have a pressure regulator like the other engines.

Back to the engine in this cae. Open the regulator until the surging (up and down) at 4000rpm goes away.

Then re-set the High Speed mixture.

You will have better luck using the proper fuel. YS engines require 20% oil. Can less oil be used? That depends on the oil that is being used. To be sure and safe a 20% oil content is specified for the warranty on the engines. You will also have better luck with a higher nitro content.

DO YOU THINK THATS IS BETTER TO SET FIRST THE REGULATOR AND THEN THE LOW AND HIGHT IDLES??
ALSO HOW MUCH I HAVE TO OPEN THE REGULATOR SCREW???
THE FUAL THAT IM USING IS 18 ALL SINTETICS

WATH I HAVE FOUND IS THAT I OPEN THE REGULATOR HALF A TURN , I HAVE THE SAME PROBLEM AND ALSO THE ENGINE RUN VEREY RICH IN THE LOW IDLE

THANKS MARCELO

Status: offline 		opening the regultor will tend to richen the low end also. So yes. 1/2 turn is a fairly large adjustment. I would do less more like 1/4 turn.

As for the 18% oil It doesn't matter that the oil is all synthetic or not. In my opinion it should be all synthetic. It needs to be 20% oil content per the recommendations of YS.

This will affect your settings as well.

Go to this site for recomendations of tuning and setup. These instructions work for all YS engines except the DZ or Dingo engines.

Status: offline 		Troy you seem to be the YS man! I got a question for ya, I am here in Tiawan and i bought a F4U with a great running YS 110 fz, it really ran well right up till I had a little ground airplane separation problem. busted the valve cover and rocker arms, i regrouped did a rebuild of it, put new bearings , ordered all the affected parts, put it all back ( included a new F4u) but now the thing will just not run well. I was thinking that the cam timming may be out, but it will crank up but it won't idle, and i can only get about half RPMS that it should, and that doesn;t last long. but it usually restarts just acts like a timming problem. do you have any good tips (or maybe pictures) to help with this. I would ship it home for rebuild, but the postage and shipping is a killer from here. They make it all but you cannot hardly buy it here if ya don't speak chinese which i speak Texan so that don't work real well. any way thanks for any info !!
