Hi,

Well i have got hold of my first Nitro car. Its a HPI Rush Evo with a HPI T16 pull start engine. Having a bit of trouble starting it.

Car is brand new. Full asembled out of the box. I charged the glow plug starter over night (14 hours) as instructed. Put the nitro fuel in the tank which was supplied by the model shop so i presume its correct fuel. Primed the fuel, correctly as instructed in the book... Placed the glow plug starter on the glow plug and gave the cord a few quick pulls. Nothing happens then the pull start gets too tight to pull any more without fear of breaking anyway.

Watched a DVD which came with it and it suggested i had flodded the engine. I followed the instructions on removing the glow plug then giving the cord a few tugs to clear the fuel out... which cured the cords pull action. Tried all the above again and no start. Cue the cord becomming hard to pull again.

Tried all this over and over about 4-5 times with no joy :(

Last thing i have done is put the glow plug into the starter to see if the wire glows, which most of it does, but the very end peice which sticks out seems to stay silver - is this the problem ?

Any help apreciated :)
 
Hi there.

Yeah it sounds like you have flooded it. Best thing to do in this case is to take the glow plug out and then give a few tugs of the pull start as you have done. By the way, it is normal for the pull start to become harder to pull once the glow plug is screwed in place. When it is extremely hard to pull/start that's when you know you have definately flooded it.

Glow plugs should glow quite bright almost a bright white colour, if not then you may have to get a new glow plug which are quite cheap. Has the glow plug been used before? - if so how many times?

By the way, pull start are notorious for the amount of times that it can take to get the engine fired up. Just try and get a nice action and keep trying it.

Hope this helps.

Whappers
 
The carb is open too much. Tune it so it is open just enough for a bit of fuel to get in for it to idle.

(I don't own a nitro car, but would love to so this is a educated guess as to why it is flooding.)
 
I had a simialr problem starting my HPI Savage straight out the box, just couldn't get it to fire. Eventually took it down to a hobby shop, got them to fit a different glow plug and it fired up first time.
 
Thanks,

Well the car is at factory settings so i didnt think it would need altering. The dvd does show how to tune the engine and how to reset it to factory, so maybe ill give that a go.

The glow plug should be brand new as this was a new sealed car!

It doesnt glow white its just an orange, quite bright but certainly not white.

Not all of the wire in the plug glows though - only the first few coils.. then peice which actually sticks out stays silver.
 
R220,

The factory settings on the Rush Evo is way too rich, lean out the high speed needle some more. When i use to have the Rush Evo with the T-15 engine in it, i remember having lots of problems getting it going. If it still doesnt start then get a mate to hold on power whilst you crank it, should help out. A nice warm day will also make it even easier.

Now i have got an OS .18 CV-RX and its a right beast now! Wheelies can be pulled at 40mph. :D

Let us know if you need anymore help.
 
Well tried closing the high speed needle completly then openin it up using 3 full turns as instructed, but still no start.

Going to take it into the model shop i got it from tomorrow to see if they can help.
 
glow plugs can last seconds, or they can last years. its really quite random to tell the truth, the amount of people weve had coming into work wantign replacements lol its quite funny.

always ahve a few spare though just in case. buy them discounted in bulk if you can
 
Is the engine even starting? Or does it start, thutting and stopping? You need to get correct combination of mix (needle valve) throttle (carb) and amount of fuel in engine (primed----flooded) Is the fuel line contanst and no air bubbles?

Glow engines can be either really easy to start, or pig. I've found the better engines are much easier to start (ie OS)

I gave up on nitro cars, toys :p

You need to lean it more then that. The setting it says in the manual is completely useless i found with mine.

Also when it floods keep the glow plug starter on the engine and it will slowly burn away the fuel in the cylinder. Wait about 30 seconds or so and it should be loose enough to start.
 
Another tip for new and tight engines is to crack the glow plug off half a tuen allowing some fuel to bypass the threads (leaks up the side of the glowplug) once the engine fires tighten the plug .

Also with new engines preheating the engine helps (hair dryer) . My son has a rush evo and it only takes 1-2 tugs to start but was a pig initially . And as saitrix said they to come overly rich from the factory which does not help .

Yep, heating the engine will certainly help. Me and a mate have Savages and they always spend a couple of minutes in the footwell of our cars with the heater on full blast. With they engine nice and toastie they always start first time :)

Don't waste your money mate, after buying a decent nitro car and replacing engine with a OS (stock engines are rubbish IMO) you might as well just buy a large scale petrol car.

A FG Marder is about £350, and comes with a reliable Zenoah engine. Twice the size of a nitro toy, handles rougher terrain and is faster, TONS more torque, and cheaper to run. It's also easier to start and you don't need the starting gear you do with nitro.

I've had both nitro and petrol- and wouldn't go back to nitro, even if it were free.
 
To people wanting to get a nitro rc: don't :)

Unless you have a lot of money to waste, that is, on fuel, parts, sliced tyers and smashed gears.
