Hi everyone

This is my first post and my first nitro car so i have a few questions.
I have been given a Thunder Tiger TS2N with a pro 12 engine.
The engine did run but had a fuel leak so I've decided i'm going to give it a clean and replace the head gasket and muffler manifold gasket, is there anything else that i should look into replacing?

I was looking at the carb tuning as i think its running too rich as throwing allot of fuel out the exhaust but can't find the low speed needle screw?

One last thing how easy is it to turn it into the 4wd model, what will i need to convert and is it worth it?

Thanks in advance Ian

it,

Fun project. I would replace the fuel line and the battery holder and replace it with a battery pack. Those cheap holders have a history of creating a run away....

I had actually ordered some blue new fuel lines but only to make it look cool lol.
Any links to a battery pack and charger that will fit.
Can you shed some light on my carb as doesn't seem to have a low speed adjustment, should i replace it?
Thanks again Ian
 
I don't think that carb has an Lsn ,it is a single needle carb with only the Hsn ,an it looks to be set too rich by
the look of the top of the needle protruding out of its housing!

Single tuning is easy ,all you have to do is start an run the car an tune until you get that high note sound
from the engine!
You need to replace the air filter bad ,it should not be ran like that!
Also ,I was going to say that it appears that someone had taken out the front pulley ,belt an drive shafts
out of the front to make it run ,maybe the pulley broke!

The air filter has been replaced just not shown in these photos, looking at the paperwork i have the parts list is not showing any front wheel drive mechanism.
What's better to have single tuning or twin tuning?20200612_164620.webp

The 2 needle carbs have to be tuned different ,the Lsn setting is a setting for the transition of idle to full throttle
in fast throttling ,it smooths the throttling out ,as in ,if you pull the throttle real fast from idle ,the engine may
have a stall or studder an possibly die ,the Lsn corrects that ,a single Hsn ,you have to adjust on what the engine
can handle with out running it too lean an over heating an destroying the engine ,but with the single ,I think
in most cases ,it will just die from starving of fuel!

So ,the Lsn is a setting that smooths the transition from idle to full WOT. ,however ,it is a little tricky to
adjust ,the wrong adjustment either leaner or richer will effect the performance!

So do you feel i would be better off keeping my carb or replacing it?

I think that you should keep it original to the car an learn with it ,I guarantee that you are going to want a
better an faster car later ,todays newer stuff ,always have a 2 to three needle carbs!

If you had got that car second hand ,chances are ,that the previous person did not tune an lean the engine out
after its break_in setting ,an lost interest in it!

I didn't buy it, it was given to me by a friend as their lodger left it behind 2 years ago.
I am re-building the engine as has a fuel leak from the exhaust manifold but i decided if I'm going that far i may as well change head gasket and potentially carb at the same time

Any eccessive fuel residue on an around the engine is a strong indicater that the engine was not tuned an leaned
out after a break_in period ,meaning that the engine is running too rich!

It is not how you got it ,it is what the previous owner did not do!

The only reason i know it's leaking from their is because i saw it dribble out lol

Here is the results of an engine that was never tuned & leaned off of the break-in setting ,break-in settings
from factory is a very rich setting an if it is left that way ,can cause massive leakage due to the high pressure
from the ecsessive fuel & compression of the engine!

Right got it. So my overhaul will fix this. Am still so tempted with the better carb but may wait after i re built the engine to see how it runs.
With the carb i have where would a good starting point be on the needle wheel?
Thanks again Ian

On that type of carb. ,you will know once you start the engine ,first ,it will be hard to start because of too much fuel ,
like on the verge of going into a hydro-lock ,if so ,I would lean an turn your needle in about a 1/2 of a turn ,an once
warmed up ,if the engine is still putting out a lot of dripping un burnt fuel out of the exhaust ,turn it in as needed as
soon as the engines RPM's starts to get more responsive an snappier when you give it quick stabs at the throttle ,
your engine will also start to get a high note sound ,at that point ,make sure that the muffler is still producing a
little bit of blue smoke!
