the piston got stuck just when it switched of.. so i had to get the top of the glowplug wrench and placed it flat ontop of the piston.. and tapped it gently2-3 times.. and clunk.. it came loose.. and all was fine..

Be carefull tapping down on the piston: You can put a flat spot in the rod bearing, another reason not to use a piston lock tool also, to undo clutch retainer nut, always use a proper flywheel tool
As suggested, use a screw driver carefully to wind over pinch, while engine is still hot, in the direction of normal engine rotation only, never backwards.
Learnt that costly lesson in my early RC days
Cheers.

Man you guys are blowing it up with good tuning advice as always. I want to +12 what grizz suggested, I don't let any local guys touch my Go motors because they are used to the short LSN tuning style for the most part and you get exactly where you are now. Great guys, just an incorrect assumption. Good news! Once you get this tuned you will need very few changes, and it will be consistent over the entire tank until it is on vapors or totally dry, with great low end power. I also want to say thanks for a really good description of nearly every symptom that occurs with this type of tune, it makes diagnosing very easy. I don't think you left anything to be guessed whatsoever. Oh yea, it probably kills plugs pretty fast with that tune as well, but they last much longer once you get it dialed. Remember, VERY small adjustments on low speed needle, I usually go a blade adjustment once I am close. Happy motoring!

Well it just goes to show that many of these selfproclaimed experts are not really experts at all
But for me as a beginner at nitro tuning, I need to ask other people for help.

The funny thing is when I was breaking it in on my own, and just following the instructions from the webpage, I was doing great!
It's just when it got more complicated I asked others for help and then it all went Pete Tong.

I'm going to give it one more Go though, then we'll see maybe tomorrow. I just need some new clutch bearings first, they are all gritty and I think that means they are ripe for replacement.

Give that tuning guide on the website another real good read over, plus the tuning tips beneath it.
If you can get your head around the garden hose comparison in the tips section it will make the tuning a little easier I think, as you can picture in your mind the fuel flow, how it's restricted, and what the needles are doing in the big scheme of things.

It clarifies the reason for richening the top end when you get lean bog (and not the bottom end) quite clearly.
This is where the long LSN carbs can vary somewhat from the "standard" short LSN carburettors found on most motors out there.

The reason for the long LSN is that it gives a smooth power band with no transition period between top and bottom end power. It works very well, but you just have to be aware that the LSN controls the fuel flow from idle right up to just on full throttle, while the HSN is really just a fuel flow tap in this design and doesn't really figure largely in the actual tuning of the motor past half throttle like those other "standard" carbs.

Tuning is a steep learning curve when your new to nitro, and it takes a while to get your head and ears around it to be proficient. Hang in there and just seek advice on here if you get stuck. There is normally someone on here lurking that will be able to help out

They pop up everywhere don't they Flanno.

Where are all the super model motors - plenty of top, lean but not skinny on the bottom and a camel toe to die for
Ahh, in a perfect world eh

Love it. Hang on, I think I may have one hidden away somewhere!!

I'v got a few engines here too........... plenty of top, lean but not skinny on the bottom and a camel toe to die for


now all I need is a woman, to match my engines

you'll be right mate; remember that old saying:" Build it and they will come".

send her to Mark flanno to get modified, a bit of silicon in the right places usually increases the top end

Thanks for the info flanno.. ive just finished the 10th tank.. and she's sounding pretty sweet.. i tried following the instructions.. and listened to the pitch of the engine.. in idle and in short bursts.. in the 10th tank it did change its tune in regards to length of idle.. as you mentioned.. holding itself at 95-105c... and also i reved the engine till it was screaming.. and i did not notice any choking through the revs.. top till bottom.. the engine was spitting a healthy amount of oil out and minimal amount of smoke.. compared to when i was finishing the 9th tank at half.. where it was pretty smokey.. but as i said above.. it has come down and a good amount of spitting is evident as well as minimal smokeyness... white in colour.. if that helps with anything..

i did have the throtle adjustment at 55-60 due to the fact that it would get to low in the rev range.. if i left it.. and in the 10th thank.. when it suddenly changed its tune.. i was able to dial that up to 90in throtle adjustment on the controller.. and it held steady.. and i gave it a rev when it started getting a little build up.. no worries.. cant wait till i have it at the last 2 tanks!

11/15 4tanks to go!! ... engine sounds to be idling well.. and is reving consistently to high revs with no evident issue.. holding as mentioned at 95-105c

will update when ive hit the 15th..

Too right Craigus A touch of silicone where it counts can really make them scream

Wow !! How did we end up down this road ?? Ah yeah, that's right - the good old average woman tune thing

back again... ive got a compact cam with hd video... so ill see if i can record the running process , this will be the 14th tank that will be seen ..

all good and she the beast will be ready for track racing tune... will see if i can get a sunday or sat. of from work.. see you at the track flanno!

last and not least.. 14th tank done... recoreded... editing to be done.. and 15th tank coming soon..

A touch of silicone where it counts and I'll really make them scream.......... THEM WHO ??

plenty of top, lean but not skinny on the bottom and a camel toe to die for hehehe

you scream, I scream, we all scream for wink wink wink
