Start car up on a stand, so that all wheels are off the ground. Then leave the car at idle for 2 mins, whilst making sure the engine is roughly 50-60*C- if not adjust the big screw on the carb, out for cooler in for hotter (1/8 turns only!!!).
After 2mins stop the engine by putting your finger onto the flywheel (the quick thingy spinning about when the engine runs.).
make sure that you can wiggle the flywheel about left to right abit when engine stopped, this makes sure piston is at the top. let the engine cool for roughly 15-20mins. then repeat the above cycle.

Once repeated roughly 6-8 times, you can run the car about on the ground, still checking the engine temp every 2 laps, (30 secs.). Once the engine starts to run quick and fairly cool, its time to play!!

hope this helps.

Oh dear, I think I'm about to start an arguement about running in. Yes Ok start your car with the wheels off the ground. BUT UNDER NO CIRCUMSTANCE mess with the carb. This has been factory set and is totally Ok for running in. Providing that you have some sort of air flow over the head ( my advice would be to leave the body off)you can run the car until the tank is empty. Then let it cool down, (the head should feel cold to the touch). Then refill the tank and go through the whole process again for at least 4 tank fulls. Boring process I know but it's worked for all the IC engines we've had. Then you can run it on the track, but still take it steady for at least another couple of tanks full. Yes it will be rich (smoking a lot but this won't damage the engine). When you've gone through all that you can start to lean the motor off but I suggest that you get someone with IC experience to do it for you or with you.

Thats another way of doing it.lol. ;D
Used to do it like that until I got an STS engine this year, which had a very good highly detailed running in guide. It baisicly said everything I said earlier, and the engine is ballistic now. I think that both ways are effective, however running at idle on a bench doesnt stress the engine at all. The max temp it got up to through all 8 times I did it was only 155*F.

Spot on about not messing with the carb straight away however if the engine is red hot then I would richen it slightly.

Either way works very well, its just up to Justin to decide.

thanks guys thats a real help

my engine flooded

i need to know how to start it!
and how to use glow starter

only one line on your sig please

[Mark Christopher]

Did the shop you got it from offer no help?

you should only use the fuel you will be running it on! why have you got 10 and 16%?

I would have to second johns method, never heard of the the other in my experience

try looking in FAQ in here and 1/8th rally cross all you questioins are answerd in there!

charge golw stick up and clip it on the glow plug!

[Yokman]

Sounds like you need basic help here to get your car started. Try this -

Make sure your glow starter is fully charged (that presumes it came with a charger, if it didn't, go back to your model shop and get one). In case you didn't know, the glow starter simply heats up the element of the plug to get the engine going. Once the engine is running you can remove it and the heat from the engine keeps the plug going.

Since you reckon you've flooded the engine, drain the fuel tank, remove the glow plug and turn the engine over a few times with the pull start to blow through the excess fuel.

While you've got the plug out, connect it to the glow starter and make sure the element glows. The idea here is to make the centre contact in the glow starter touch the top of the plug with the outer part clipped around the bottom (nut shaped part). If the plug doesn't glow either your glow starter is flat (shouldn't be if you've just charged it) or the plug is blown and you need a new one.

Assuming the plug glows OK, put it back in the engine and refill the fuel tank with whichever fuel you intend using to run the car. It should run happily on either 10 or 16 per cent fuel but 16% will give better performance.

Remove the pressure feed pipe (that's the flexible tubing that runs from the exhaust to the fuel tank) from the exhaust and blow gently through it to force some fuel into the carb then reconnect the pressure feed.

Put your car on a stand or suitable alternative to keep the wheels off the ground. Connect your glow starter to the glow plug. Switch on the radio and car.

Pull fairly vigorously on the pull start a few times and hopefully the engine will burst into life. This is not a test of strength, try and keep your pulls fairly quick but stop just short of the maximum travel.

Assuming the engine starts, blip the throttle control on the radio a few times to warm it up, remove the glow starter from the plug and then follow the advice others have given on running in.

If none of this works, there are so many variables that could be wrong it's really difficult to diagnose remotely. Either get help from somebody with a bit of experience or take it back to your model shop and get them to sort it out.

Sorry if this sounds a bit patronising but it can be difficult to judge how much or little you already know.

at the moment i know nothing!

i bought it from modelsportuk and i live 150 miles away from them! if not more

when i cover the heatsink with a thick cloth and pull the pull start is easy to pull but when the glow plug is in it wont pull at all plug is alwright and fully chargedall that happens when i pull the starter is fuel comes up in the head

please help

kIEth ;) nice description can i use that in FAQ??

how do you mean into the head? you should have fuel above the piston or the engine will not work! but to much and it will lock up!
you are pulling the cord in fast short bursts?? do NOT pull it out all the way!

is normal to be harder to pull when the plug is in.
im affraid it might have been cheaper at the shop you bought it but your local shop would now be offering help!
where in Uk are you? we can maybe get you in touch with somone to help!

[Yokman]

From what I can gather, your car is fitted with a Force 15 engine. This is appears to be an OFNA derived engine and if you go to www.ofna.com and click on engines you will find a picture of it. If the picture looks like your engine, click on Manuals on the side bar menu and download the instructions for the Force 15 engine, have a good read at them and check the settings on your engine adjustment screws.

If the picture doesn't look anything like your engine, IGNORE the rest of this message as the setting information may not be right for your engine.

From your description, it sounds as if your main needle is set too rich (that's the screw inside the brass sleeve that sticks vertically up from the carburettor). Screw it in (clockwise) until it stops turning and then unscrew it (anticlockwise) 2 full turns. Follow all the instructions I gave you earlier and try starting the engine again. If you still find it difficult to turn the engine over using the pull start try loosening the glow plug slightly. New engines can be very tight to start with but it will loosen off as it runs in. Once you get the engine started, tighten up the glow plug.

Hope this helps, if not you'll need to seek expert help. Try and find a club in your area that runs nitro cars and take your car along and see if anybody can help you.

i spent half an hour on msn last nite with the poster and i think i got him sorted!
seems the carb was at full throttle while he was trying to start it!!

[justinbowness15]

thanks for all your help guys i evwntually got it going yes!!!!

but now as soon as it starts it cuts out a few secondls later

also i have to have the glow plug nearly all the way out to get it going just so i can pull the the pull starter

when the plug is in all the way its impossible to start (or pull the starter) why is this

[Mark Christopher]

justin i keep saying its because 1/its new 2/ the piston is tight in the liner 3/ it has high compression!
it IS normal

lift idle slightly when its going or gently blip the throttle!
and
im cartman on here! arnoldrimmer on msn and mark christopher on email so you have asked me all your questions 3 times now!!

[justinbowness15]

oh sorry

thanks for helping though

[NiMo]

Mark, you might get some peace now as Justin has got his motor running, and now he's asking me how to stop it.

[whoopass_racer]

and me :'(

[justinbowness15]

sorry everyone :'( i dont intend on bugging everyone its just hard for me knowing nothing you must have been there once

and now the wheels turn when the carb is shut slide one

[Mark Christopher]

turn the idle down screw the screw out!!

[whoopass_racer]

Not too far though, or the carb will go ping! Small adjustments at a time.

[justinbowness15]

is this the screw that has the spring underneath?

[NiMo]

Yes

[justinbowness15]

thanks everyone to has helped me

you guys are really supportive and helpful!!

sorry for bugging you :-

thanks :D

justin

[justinbowness15]
