Hey Robert,
Your logic is sound in my opinion. Good Job…

Just wanted to let you know that I made a couple more flights the other day. A couple guys came up to me said "that thing is really hummin".
Here's a couple pics of the plane (TF Sea Fury) with the RCGF 20cc. At 14 1/2 lbs, she is a handful to land. Looks really nice coming in with full flaps and a little throttle.
Thanks again for getting it running!

Don't want to hijack the thread, but thanks to Captmicom
Got my engine back today and have it mounted on my Cub in time for the Cub Fly-in. Runs great for a brand new engine. Thanks again. When I get ready for the bigger one I will contact you.

Hey Guy,
You are very welcome. Did you check the needles? I am at 5000 ft. ASL so it will need some fine tuning. I hope that you get long life out of her. Let me know how it goes this week end.

RE: RCGF Engines
Humm, lost my post. I have a rcgf-26 that I need to know the factory settings on the High and low speed needles. Mine runs OK but at WOT it just seems to have miss in it. Almost like it need to be leaned out. I've turn the needles in, out, back and forth but can't seem to hit the sweet spot.

Any predetermined carb settings are only going to be good for some assurance the engine will start and run when set to them. They MAY be close to optimum - but please be assured there is no guarantee the engine will be running at optimum using them! Either one or both could run much better 1/4 to 1/2 turn, richer or leaner, from the predetermined...
They are meant as a starting point, meaning that if the engine won't start/run on them, there's something else going on. That's it. There are WAY to many variables to account for that use these adjustments to compensate.

Check your plug the gap may have change or gotten dirty with oil build up carbon.

Amen. I often wonder even why people ask. Each motor is different.

The reason I asked was because I had moved the needles around so much, I needed a starting point to start over. I'm pretty good at tuning glow engines but this is the 1st gas engine I have owned. Just doesn't seem to peak like a glow one. I do realize that each engine is different but if you have a starting point it makes it easier to fine tune. Like most glow engines they will tell you to start with the HSN out two turns. Then go from there.

Per the manual, the DLE 20 is 1 1/2 on high, and 1.1 on low. You don't have to be that precise. You are just trying to get it started and then tune it from there.
Acerc,
Sorry for answering a question directed towards you. Just trying to help.

Thanks ahicks- I was starting to get frustrated.

Try not to get frustrated. What really helps A LOT is tuning these using a tach. You can really dial in the high end, then set the low for good transition.
You said that you had to turn out the high 3 turns. If that is 3 complete 360 turns, then that sounds way too much. A good starting point is 1 1/2 out on the high, and 1 1/4 on the low. You should only have to make minor adjustments from there, maybe as much as 1/2 a turn.
There are some really good tuning techniques on here. If this is your first gasser, then you really shouldn't try to tune it "by ear" like a glow motor.
I attached a file (if it worked) that should help you.

I have printed the file and btw it did work. I will have to turn the plane upside down as the engine is inverted. When the rain quits I will put it on my starting bench and work on it. Thanks for the information.

RE: RCGF Engines
I am putting a RCGF 45cc engine in my Top Flight GS P51 and need a bolt to attach the spinner cone. I think the shaft is treaded for a 6MM bolt. I need a 4" long bolt and can not find one. Does anyone know where a bolt this long can purchased or should I retap the shaft and use a regular bolt? If I retap what size bolt should I use?
Thanks, P51Tom

RE: RCGF Engines
goirish, glad you got the help you were looking for.
mesaflyer, glad you could help. That's what were here for.
p51tom, NAPA, Carquest, or any other real automotive parts store.
And as stated before, don't depend on ears to tune an engine get a rpm gauge. It will save you a lot of headaches.
On a side note, why do some partake in belittleing those who ask what they don't yet know. To those who know it may be a stoopid question but for the rest it's a legitimate question.
So for those who don't know keep asking. God know's I ask alot, sometimes even when I knew the answer and just wanted someone else to verify.
