Pump gasoline in it's self is a witches brew of solvents and aliphatic resins that are brewed to behave predictably at a given temp and altitude. Defferent refineries with different refining processes make chemically different fuels, all called "unleaded gas". So I guess where ever you are, there it is. Coleman fuel will not run in an old leaded 4 cycle gas engine, for long. Hard on the top end and bad pinging. 2 cycle's don't seem to care as they don't need lead for top end lube. I don't think I'd pour it in my car, pump gas has top end lube as an additive. So let your engine mfg, warranty and your consience be your guide, because the gas you buy in L.A. is different from the gas you buy in Chicago, Miami, N.Y., Denver, Vancover, Hong Kong or London. So, where do I have to drive to get the good gas that's going to run right in my gasser??????
I will try and answer 2 questions here: One being on an earlier question. First, I run the 16X6 on my CRRC 26 and will switch to 16X8 once it is totaly broke in. This is on a Seagull Edge 540 60. It does, however, fly great on the 16X6.
Second: Jodi was right on by his statement. CRRC, DA, DLE and BME are some of the engines that are being run today and none of these manufactures will warrantee these engines run with Coleman Fuel.
A buddy of mine tried it in his BME and quickly removed it when he started having preignition and idle problems with it. Will it happen to every engine? I don't know, but why take the chance!
Have been running 32 to 1 lawn boy ashless for breakin and will switch to Amsoil Saber at 50 to 1 there after. And no, I will not run 100 to 1. A little more oil is good insurance in my book and generally what most call for. Again, the engine manufacture will dictate what I run in my engines.
Just my most humble opinion!

I guess my post was not really so much what I learned about coleman fuel but what I learned about pump gas. I would never even think of running Coleman in my expensive toy of which I am very picky about the gas that goes in it. With the ethanol that's in most of todays gas I'm a firm believer in mixing Stabil Marine with every drop of gas that goes in it and my truck too. It keeps all the ethanol in suspention and not gelled. I have not experienced any hard starting or dieseling at shut down and I'd like to keep it that way. Many others have who've refuse to treat after the recient decline in fuel quality. Flying our toys around (I know they're real airplanes, just small ones.) is a little different than having my fat @$$ in a boat in the rapids and fast water. So I guess let's get real, we're discussing fuel to run in our toys, one gallon at a time. Again my best advice is to follow the mfg's warranty reccomendations. Do I think Coleman fuel will ruin your motor? Probably not. Will you realize any performance increase? Not likely unless you doctor it with the additives that are missing for your location.

So why bother? Go to the gas station and squirt some in the can after you dump the oil in. Be glad it's a gallon and not 80 for an afternoon of fun.

Even better yet, go over to the neighbors house and ask the guy doing his lawn what he runs in his trimmers and whackers......... bet he puts a lot more hours on his engines than any of us ever do and they are his life.

Remember, this is a hobby and something most of do for fun. No sence at all getting any panties in a bunch. Save that for work or the jerk driving next to you.......

Hey, Bodofish, well said. Just to let you know, I was not flaming anyone. This is why I love this site. Always good information and even though I am 64, I learn something each and everyday. Hey, you are never to old to learn.
I just installed a DLE 55 in my 27% CAP and I can't believe how well this engine runs.
Buddy of mine who flies DA and BME, dropped his jaw when he witnessed this engine and its power!

Hey Anderson, hows it going? Your weather up in TN is not good right now. However, we have had some wind issues here and the last 3 days, the fog is so thick you can't fly until 11.
I sure did enjoy my trip up to my old stomping grounds. Had a great time at the Madison field. Sorry we could not hook up. Maybe another time.

Yea, it's alright, Joe. I swear, I'm cursed. Everytime I say I'm gonna meet up, something else comes up. lol. Glad you had fun up here and got to meet Mikey.

CRRC, still scooting the Frenzy along.

No worries, just passion for the sport/hobby. I just crack up over the dyed in wool, cast in cement attitudes towards many things. Gas and oil go figure. I'm a technology / computer consultant, things change so fast in our industry if you make up your mind it's going to be one way HA it's changed because there's something new. Gotta go back to school again. It's tough on old guys.

Hello all,

I hope there is help to be had. I have about 2 hours of run time on my GF26I V2, broken in per instructions. I noticed it is getting harder to start, and making some funny noises, so I read around and checked the engine for the usual culprits.

I have the 793? carb (Not the 805), and I checked to make sure the machining issue is not a problem on mine. I took the carb apart and sealed all parts of the carb / spacer, as I saw some fuel coming from between the gaskets.

I think the carb is now in order, but I noticed a noise coming from the motor, only noticeable when it is not running. I will grab the prop and rotate it back and forth around BDC (and TDC), and it clicks loud. I opened the back of the crank case and found about 1mm of lateral play in the lower rod connection to the crank. It is not moving laterally on the bearing races, but where the inner bearing race goes over crank pin. I have attached a picture for better explination, the red arrow is pointing at the part that has play. Also see the video I took of the popping noise I am talking about.

I simply need to know if this is normal or if I have a problem.

Thanks for your help!

Lateral play on the con rod big end is normal. You will get a certain amount of lateral play at both big and small ends. There should not be any detectable side deflection though

Just seen your vid it sounds like you have play on the wrist pin, a damaged crank bearing or possibly a broken ring moving in the piston groove if you cant see any side play in the big end. Just a thought....the hall sensor isnt rubbing against the hub is it?

The hall sensor is not rubbing. I have wonderful compression, and after sealing the intake, it fires right up like it was before.

The sound comes from the big end on the con rod, as well as the side to side is mostly on the big end. I do notice a tiny bit of play on the small (piston) side of the con rod.

I had an evolution 45 that was making almost the same sound and like your engine was getting harder and harder to start. Finally I couldn't keep it running for more than a minute. It ended up being the nikasil plating on the cylinder wall was letting loose at the top of the cylinder. I replaced the jug and have not had a problem since. Hopefully this is not your problem too, but it is an idea if you can't find anything else.

Oh yeah I replaced the ring too. I know someone would have hazed me for not stating the obvious.LOL

I guess it would be in my best interest to pull the head and inpect the piston and sleeve, just to make sure...

Hi I need help with my gf26i that has picked up a bad vibration.I thought the prop connecter and hub was damaged by a bad fall so i fitted a new hub and shaft but when i turn the motor with a dial gage fitted to the thread section of the shaft the shaft runs out by about 1mm . I dont know if the problem is with the key not lining up or is it possible for the crancpin to bend.
Thanks,
Andre.
