Check the engine for pinch. If the engine is a cheapish one, or the one that came with it as an RTR, from new you should be able to just turn the flywheel beyond the pinch - with effort. More expensie/competition engines will tighten up and lock, won't be able to from new.
But if you can turn it past pinch relatively easy, then it doesn't need to be run in. If its an expensive/competition engine and you can turn it past pinch with some effort, it doesn't need to be run in.... it'll have done a fair few tanks already. Incidentally, if it is tight, after running it make sure the flywheel is turned so it can rock - makes it easier to start next time, and its easier to do this before the engine cools otherwise you may need to do it with a screwdriver. |
if its run in and has just stopped running it will be the glow plug,charge up the glow start,CHANGE the glow plug and it should be ok,one thing i would say is when ever the engine has been run,as soon as you can make sure the piston is at the bottom of the piston sleave,if you take the the exhaust off the back of the engine,turn the fly wheel so you see the piston move down to the botton through the hole,turn the fly wheel so you know what it feels like at the top and bottom,then when you have the exhaust back on and its in the car you know what it feels like,this will make the engine last a lot longer as the sleave cools before the piston,if you leave it,the sleave will get stretched due to the piston still being hot and larger than when its cool,

If you have not got any pinch then send it to me and I'll re-pinch it for you. Set it back to factory settings and then run it on the 25% as been advised. It sounds like you are too rich and its putting the glow out on the glow plug. Start tuning you top end needle clockwise (leaning) 1/8 at a time until you've got a good crisp plume of smoke coming out of it until you have hit full throttle. if you have turned it in too much you'll have fuel starvation and your engine will cough and not get full throttle. Richen the top needle up a 1/4 turn. You then will need to set the bottom end needle up. You need to keep an eye on the tick over because as you lean the bottom needle (clockwise 1/16th at a time) the tick over will start to race. So keep turning the tick over down.

Nitromethanol is added to the fuel to make the engine run cooler - so it can be leaned out further - thus higher performance. |
cheers for all your help guys, im going to give it a go when the weather clears up a bit, as there is so much snow about now
cheers james |

The nitro content will make an engine run cooler the higher you go on the nitro |

i did read your post mate, just someone else then said lower was cooler. I reset the needles back to factory settings, fully charged and changed the glow plug ect, but it still wouldnt start :( :cry:
im really stuck now..... |
its working now :) thanks for your help guys!
|
Yeah, they tend to need a little persuasion. Also, 'factory settings' are usually so rich that they will be a pain to start. Sometimes, return to factory, then lean an 1/8th on both needles.
Electric is better though... |
Fuel
I remember many years ago I bought a small diesel aero engine.
It wouldn't start. i tried for days, weeks, out in the garage long into the night. Wouldn't start. In the end my dad said "you'e wasting you're time here. Buy some different fuel". I did, and it was running fine in 5 minutes. |
There is a lot to be said for even shaking it up before using it. I always have, afterall its going to get shaken like mad in the car.
