Status: offline 		I got my ST G-3250 running today and what a nice running engine. I have Iron Bay regulator (muffler pressure ported), 5% nitro, 18% oil, 20 X 6 prop.
I will put 18x10 on it tomorrow (just got it from Tower Hobbies).
It took for a while to get it started, but once I got it running I couldn't believe how smooth and strong it runs. No issues in the middle range at all
Aceleration is awesome with no hestitation from any throttle settings. High speed needle is not very responsive (slightly on the rich side ) rich/lean turning possibly due to higher pressure in the tank (regulator is working awesome). I am realy impresed with this engine, another Super Tigre didn't let me down.
Only question I have is where should I leave the High speed needle setting since I can turn it either direction a lot with no change at full thrrottle.
It doesn't seems to run hot and there is a enough oil smoke, so is running plenty rich.

Arch any suggestions on the High needle?

Status: offline 		That is one thing with the IB regulator. Your high end will become very broad. I would start with it where you know it is rich, and you can slowly lean in from there til you get the performance you want, as well allowing the motor to stay cool. As long as you have a good rich exhaust trail I wouldn't worry about it. That's usually a good sign that you are in the right area.

Status: offline 		Arch,
Thanks for the info. I will leave it at the rich side, doesn't seems to bother the engine at all.
I was little skeptical after all the posts about midrange issues. This setup works better than I expected.
By the way my tank is way back and higher then my engine bolted to the test stand, and it has no fuel
starvation or flooding issues. Now I now I can put my tank right on the CG in my Goldberg Extra 330 77".

Thanks again for the top notch support.

A question from the uninitiated..
If the regulator requires "pressure " to open it, albeit only a small amount from the muffler or crankcase,.....then how do you prime the motor for start before there is any muffler/CC pressure. Catch 22?? ..

Status: offline 		CG- I, also have an Evolution 1.0. Installed on Seagull Extra 260-90 ARF. It flights OK right side up, but in -G maneouvers the engine quits. If you do a figure "M" after the inverted outside loop portion quits also. Have you come up with any solution? I filled the muffler with steel wool to increase tank pressure, replaced pick up line, wrapped tank with foam rubber. No luck so far.
Any comments/suggestions?
Anything will be appreciated

I got it fron Arch years ago and since I fly YS only needed it once.

Where is Cedar Park, TX? I'm just outside SA and at one time was the production manager for Iron Bay. I can answer any of your questions.

Status: offline 		Hi Arch,
Cedar Park is in the NW suburbs of Austin. I fly R/C in Georgetown which is about 20 miles N of Austin on HWY35.
As I mentioned before I'm having problems with a Webra 1.20 before and now with an Evolution 1.0. They both do the same thing and it's that they quit when pulling -G. The airplane is an Seagull Extra 260 90. I flew pattern in the '80 and Rossi .60 was the master engine. Never had this kind of problems. I have replaced pick-up lines, surround with foam rubber the fuel tank to no avail. Do you think that the regulator may help.
Any suggestion will be appreciated.
Rene

Status: offline 		Hi Arch , or anyone else who might be able to help me...I know that this is an old thread, but I have misplaced my instruction/diagram sheet on how to do the plumbing setup for a 2 stroke engine. Ive got the ironbay regulator and I am going to use it with a Thunder Tiger 46 2 stroke where the fuel tank is higher that the carb, lots higher, due to the design of the plane, like appx 1 and 3/4 inches.
The engine tests reveals that raw fuel is siphoning out and pouring out from the muffler when the engine isnt running.
I would aslo like to move the tank back another 3 inches or so to place it over the planes cg, and I hoping the IB reg would allow me to do this ( ?)
Think I can get away with using just muffler pressure? I sure hope so since this would be the easiest for me to do.
Any pictures or help with the above setup would be certainly most appreciated!!!!!

And by chance, does IB still operate /still around or are they no longer making the regulaors for sale?

Thanks SOOOO much !!!
John

Status: offline 		I've used both the Cline and the IB regulators.

Yes, you need a regulator if you are going to pressurize the tank. The Cline and the IB are demand regulators so they only send fuel when the carb requests it. Without the regulator you can and will flood the carb.

Both units have a check valve that captures the pressure from the; crankcase for a two stroke and muffler for a 4 stroke. The regulator then allows the fuel to flow only as needed.

If you have an engine mounted where the carb is well below the centerline of the tank and you are flooding problems during idling the regulator will solve the problem. BTW a pump is not going to help this situation.

My first installations were for a low carb situation. The Cline did a superb job. I went from problems keeping the engine idling to being able to leave the throttle at idle the entire length of the runway and more. The bonus that I did not expect was that the engine run better in all orientations. When going to a vertical climb the engine does not lean and in a vertical dive the engine does not go rich.

The Cline is a lighter unit and works well. The IB is a little heavier and also works well. However, I prefere the Cline because it uses two standard size nipple. The IB use a very large nipple on the input side and makes connecting and placing the unit much more difficult. I have 6 Clines and 1 IB. Both are highly recommended.

Status: offline 		I've used the Cline regulator on a couple of Moki 1.80 setups in the past. It worked well, so about 4 or 5 years ago I went ahead and set up an OS 160 FX with the Cline. That was an utter failure. I could could not get it to work at all. I came to the conclusion that the check valve on the newer Cline was the culprit, and since it was far easier for me to just drop in a VP30 pump, I never went back to the Cline again. For whatever reason, the newer check valve was this rubber bladder "duck call" style device, and it didn't work at all. I'm quite sure that the pressure regulator would have worked just fine with the check valve that the Cline's used to come with.

Status: offline 		Yeah, YS would not airdrop a check valve to me at the field that day. Luckily, the VP30 was ready to drop in. A solution that is 1/2 the price of the Cline and less maintenance too.

Will a Cline regulator work with an OS 70 Surpass? I've seen them on 2 strokes, but am not sure about a 4 stroke. Comments?
Thanks,
Kevin

Status: offline 		I have the Cline on two different Saito 125s (four stokes). Works great. I did wonder about only being able to use the exhaust pickup for tank pressure. However, it seems that on the four strokes this works just as well as the crankcase pickup on the two strokes.

BTW we are talking apples and oranges when people start sticking the VP30 in this discussion. The pump will not do what either the Cline or the IW regulators do. Maintenance? There is none on either the Cline or the IW regulator.

I am using both the Cline check valve (new) and the YS check valve. So far both have worked fine. Just flew a Delta Vortex with an OS 95AX and the Cline with the Cline check valve. I must admit a preference for the YS. Why? I must just like stuff made from metal.
