Car Boot Subaru Nitro - tips please! (never had Nitro before)

[jonny_bravo]

£20 got me a boxed Subaru TG10 MK1 with radio gear, fuel, glo starters etc ,. apparently the radio gear has an intermittent fault,.(looks like a dodgy battery cradle so far )

Now then, how easy should it start?,. I had a quick 10min effort this afternoon,. but then realised I was just flooding it,  I have one of the glo starters on charge at the mo so I will have another bash tomorrow (just tested the plug,. it glows nicely) 

OOh yes,. stopping the engine,. whats the best way?

Cheers for any tips!

As long as its in tune (air/fuel mixture set right) and there is good compression it should start within 10/20 pulls maybe more if its a bit worn. To get a nice bit of fuel through to fire it up when its not been started in a while just give it 3/5 pulls with a finger tight over the exhaust hole and this will prime it for you, too many pulls and you will hydro lock it (piston cant move due to bore being full of fuel) if this happens take out plug and give a few pulls with the car upsidedown to clear it. Clean air filter if its a sponge one in warm water and washing up liquid, dry out in airing cupboard then apply some light oil to catch dust/dirt 3 in 1 is just right.

Best way to stop the engine is by pinching the fuel line feeding the carb not the one going to the exhaust obviously, or if in a hurry either block the air filter or a finger over the exhaust.

Hope that helps[]

Don't pinch the fuel line but use the other 2 methods (be carefull not to burn yourself when blocking the exhaust) as otherwise the motor runs shortly very lean due to lack of fuel and lack of fuel means also lack of lubrication.

Coincidence - I also got my nitro Kyosho running this weekend, after 4 years in the shed []

If it's not been run for ages it will probably be all gummed up

inside.  Nitro fuel is famous for glueing carbs together as it

goes very sticky when it dries.

First of all, screw the mixture needle all the way in (clockwise) until

it stops, making sure you count the number of full turns.  Don't

tighten it otherwise you could damage the jet.  Note the number

down, as it will be a reference for finding the right mixture later.

Next, unscrew the needle fully and remove it.  Get some carb

cleaner from Halfords, and blast loads of it down into the hole. 

I recommend you wear eye protection when you do this, as carb cleaner

is under high pressure and can have air bubbles that squirt back into

your eye.  Trust me, this stings - a lot.

Pull the starter for several minutes.  If you're new to nitro,

remember not to pull the starter to its full extension - just a quick

flick of the wrist is enough.  Pulling the starter will suck the

carb cleaner into the motor and wash all the gunk from inside the

transfer ports.

When you're done pulling through carb cleaner, pour a bit of fuel into

the carb and do the same again - this will wash out the carb cleaner -

it won't run very happily on carb cleaner []

Finally, give the mixture needle a good wipe and screw it back in fully

(remember the rubber o-ring; don't overtighten) and then screw it back

out by the number of full turns you noted previously.

You should be about right to get started now.  Prime the motor

with fuel, attach the plug heater, and give it a few pulls - it should

fire up pretty soon.  As for getting the mixture adjustment spot

on, I'm about to post a thread on this very subject - because I'm not

sure myself []

Cheers guys,. will have a go tonight!

Most of Tamiyas nitro engines should start with the needle turned out 2 1/2 - 3 turns

Also bear in mind that even though the glo-plug may glow nicely out of the engine it doesn't mean it's good enough when it's mounted in the engine, most problems with nitro engines are plug related and normally just fitting a new plug will cure the problem

Oh and if you're UK based try to AVOID the Model Technics fuel it's very oily and can cause you quite a headache when trying to tune the engine

Fuels I and many people would recommend are Byron,Blue Thunder and Tornado(which is available in most Halfords stores!!)

Well I got it running [],. think the mixture is way too rich though - will try the 2 1/2 - 3  turns of the needle that fatboyslim recommends.
