Howdy Shadow,

Well, I am by no means an expert on RC, but I did stay In a holiday inn express once.....actually, having been a small engine mechanic yrs ago, it sounds to me like maybe you are getting too much fuel. The excess smoke would come from the unburnt fuel (fuel that does not burn fully) and the stalling would come from the near 'FLOODING" of the engine.
If I am not mistaken, your "fuel line" would be a small piece of plastic tubing, is it possible to "pinch off" the flow of fuel to just a trickle? Is there anyway to slow the flow of fuel by adding a fuel filter maybe? if there is any sort of true carbuerator with an air filter, try removing the air filter to allow more air in for the fuel to burn.
OR...............even simpler, if there is an "air" or "fuel" mix needle valve, restrict the fuel and increase the air. It may even be possible that you have bad fuel....with some sort of contaminant in it...ie....condensation, oil etc...
Anyway, maybe one of the other guys mentioned above will reply.

I hope this helps, have a good day,

Greg

Hello Shadowmaker,your engine has all the signs of being over-rich,Glo engines do run a bit smoky due to the castor oil content,once the engine is leaned out ( via the needle valve ) then it should run properly,however you could have a blockage in your needle valve assebly,to clear this remove the feed pipe and place a piece of fuel tube onto the end,then remove the feed from the tank,next blow through the pie to clear any obstruction,glow fuel can settle and cause tiny molecules,the castor bean has fibres,especially as our fuel is a second and even third pressing of the bean itself.
So obstruction will not help and give the impression that your engine is struggling,so clear that first,then set up the needle by aprox 2-3 turns out to start,then slowly move the needle inwards again,that should sort the problem.

Not knowing a great deal about engines such as this but based on what you say a smoking engine is possibly running 'rich', i.e. too much fuel.

It is important to note that too much fuel will usually give you a black smoke but too much oil will give you a white smoke.

Too much fuel could be as a result of a problem in the carburation process, maybe a worn needle is allowing too much fuel in or, another possibility, you are not getting enough air so I would have a look at any air filter or air inlet arrangement you may have fitted. Is the inlet blocked by something etc.?

This would give OK running at idle but smoke and poor performance when the throttle is opened.

i have a ts4n sport too (although mine has no engine )

you need to richen it out a little

tune it so it has a decent amount of smoke and power but is not overheating

your engine wont last as long if it is overheating

shadowmaker

i do have white smoke coming out when i open it up and then it splutters abit then when it dies there i a bit of steam coming off the engine is this normal or is it over heating?????

Phoenix

where about from ?

if it is too lean it will behave like a rich engine except it will overheat

best thing to do would be to reset the needle to factory which is 3 turns out

then lean it out a quarter turn rin it and then lean it out in 1/8th turns until you get the best performance without it overheating

shadowmaker

it is steaming from the top part near the glow plug on the cylinder head

Phoenix

ok its possible that your glo plug isnt making a proper seal to the engine head

give the glo plug a little tighten up if that doesnt work go to your model shop and get an os 8 glo plug for it

when you have an air leak in your engine it will cause it to run poor and overheat can even do it when its rich
