There is some natural priming action due to the pumped carb. A finger over the exhaust won't work the same way as with a non-pumped suction carb like the glow Saito engines have. I use an electric starter, first start of the day takes a couple of seconds to draw fuel, subsequently it lights off on the first bump.

Hi fellow FG-60 flyers

I took the dive and bought two MRS ring collectors (fg0 and fg84) from ebay here in europe two weeks ago. Being about €100.- cheaper each than importing a keleo I thought "what could possibly go wrong..."

Truth be told, nothing. They are really top notch and very clean craftsmanship. I contacted the seller and turns out its a small company in germany that makes them.

Very happy with mine and a nice alternative to keleo.

Now, I am not connected to this company in any way (bought my two rings at full retail), I did however allow him to use my videos for his shop. Just so that theres no misunderstandings here :P

I bet they have better customer service than Keleo many Keleo have broke and no warranty.

CRG, the link you provided shows the Keleo exhaust ring, not the MRS ring.

CRG... From what I can see on mine from experiments I did over the last few days, this engine will draw fuel with the exhaust sealed just like any other Saito. Mid throttle, ignition off, thumb over the exhaust, give it 2-3 turns in normal rotation, throttle to idle, ignition on, cold started every time with no fussing.

Not really any cheaper for us here in the States, plus it says seller won't ship to US. Good for you though to have other options.

Hmmm, I tried that and it didn't work. Maybe I didn't quite seal the exhaust. I'll have to try that again.

You can't pressurize the fuel in the line (which is what your doing) without having somewhere for the air and fuel to go. In order to do that the barrel has to be rotated to at least 1/2 throttle or so, but then you wind up dribbling fuel all over the place out the throat, which I don't think is a good idea, at least not to excess. Granted, the lines I used were pretty long, it just being a experiment using a primer. It would work better with shorter lines, but I'm still concerned about the dribbling situation.
Thanks for experimenting with this. I tried it too and didn't have good results. I connected the bulb between the tank and carb and it wouldn't draw fuel. I then switched the lines and it would draw fuel fine when I pumped the bulb, but then I started the engine and it would only run for a second, wouldn't draw fuel on its own. Not sure if these bulbs need to be hooked up differently.

I probably should note that I'm using a 2 line setup from the fuel tank, so when I'm fueling, I'm also filling the line to the carb, so I don't have much air in the lines. When I was "playing" with the primer bulbs, they'd work fine in just a jug of gas, didn't work so hot in the planes fuel system. One reason is the air has to have some place to go, ie through the carb, but you also get some fuel. Bottom line is you get a big mess with the possibility of forcing fuel into the engine... big no no there. Note also when I'm fueling, or defueling for that matter, the barrel of the carb must be closed, so I've set up my radio to handle that.

Just tried again to choke/prime by covering the exhaust and flipping the prop, fuel line empty. It does not draw fuel, throttle open or closed. Looks like the best way is indeed building some kind of choke to cover the carb, blowing into the vent or a 2 line fuel setup with a T. The latter does require to close the carb completely though or fuel will run out of the carb during fueling. I think I will eventually just go with the T.

Well having a two line with a tee definitely puts gas to the carb without fail! Maybe I was just drawing a snort of raw gas into the intake, but it sure worked good yesterday especially on a cold start. Anyway, by time I got done I'd had it buttoned up with baffles and cowl and ready to fly except I need to shift the battery to the rear for CG purposes. The Saito wound up being about 1.4 lbs heavier than the G 62 it's replacing.

For what it is worth I set it up with a three line system. One to the carb, one to the Keleo exhaust which is also the overflow, and one fill line to the tank. It works just fine with no mess or fuel going anywhere I don't want it. No T
s in the system just three lines to the fuel tank.

I usually run a 3 line system as well. But this is about finding the simplest way to choke/prime this engine. Of course what seems best for one won't work for others.

Anybody but me having issues with their FG60 not idling down as quickly as it should after running at WOT? If there is a vacuum like, I cannot find it! Thanks

I've had that happen if I got the low speed to lean. Fatten it up a little and that should take care of it.

Thank you! I'll give that a shot. I figured I had it too lean. :-)

To choke it since there is not much room between the carb and the firewall we took a flat piece of metal with sticky foam on one side and covered the intake with that. With throttle wide open it seems to work well. We choke it by pulling it through instead of flipping it and of course with ignition off. Never ran one of these before, it's a very new experience.

As a rule of thumb you want the low speed needle as lean as possible while still giving quick acceleration from idle. And the high speed needle as rich as possible while still giving good power.

If anyone is interested, I have a custom ring muffler for the FG60 for sale on Flyinggiants and RCgroups.
