engine needs fixing

[ohsnap]

2revo1maxx is right - don't be wasting your time dumping fuel into the carb.
You need the carb to be working for the engine to run and all you're doing now is drowning the crankshaft and fouling up your owb.

I wouldn't give up on this engine just yet.
OK - so you know that the owb is in correctly and you're sure that the HSN is blocked.
You know what you need to do. It needs to be cleaned.
Do you have denatured alcohol?
If not, what about or carb/choke cleaner, rubbing alcohol or windex?
Q-tips, paper towels?
Clean it so the fuel flows properly.
Another trick would be to soak the carb in nitro fuel as it can dissolve gummed up fuel.
I would unscrew the HSN (and clean it seprately - which you would have done by now anyways) and allow the fuel to work it's way into the body of the mechanism.
You just need to clean the sucker out and get the fuel flowing properly through the fuel line and into the carb.

Your brothers car:
Is it missing the axle or a driveshaft/dog bone?
If it's an axle, sounds like you'll need to replace that for it to run.
If it's a driveshaft, you could run it as 2wd.
Got a photo?
The exhaust screw that is missing is a common and inexpensive part that your lhs should have in stock. Worst case - if you've determined that your other engine is beyond salvaging, you should be able to pull one from it.

Sorry to bring this old post to life but I've made progress on the car,the weather has been bad since around November but I'm getting back into it,I've scrapped the pull start and I use one of the starters where you put the rubber disk against the flywheel,turn it on and it spins really quickly and it starts the car.the car starts and it can drive around but it has no bottom end guts(takes a while to get enough power to move at a decent speed)and it is being a real pain to tune.(this is still the old car BTW).It also used to drive around for around 3 mins then just cut out and not start for 5 mins but it doesn't do that any more.One last thing,does anyone know where the LSN is on the carb.

You have made some progress so run it for now then pick yourself up a new engine.Sounds like its tired.

 

[cameron]

I just wanted to mention that I think when it used to cut out after a couple of mins,it was because it overheated because when it cut out,it got really hot,but like I said,it doesn't do it any more,could that have anything to do with why I find it really hard to tune.

The low speed needle is on the carb slide, sounds like it needs to be turned out a hair.

yup turn out you lsn (and mess with the idle after to get her to idle after) If you end up moving lsn far enough you will have to adjust the idle screw.. U should have a temp gun to make sure she aint getting to hot or running to cold.. Another thing is congrats on getting her running!!!!! well good luck and keap us in the loop.

what are the effects of using old fuel only I've got some that has been in the garage in an airtight container for about a year it is always cool (about 10 Celsius) and dark ,it's 5% nitro which is what's recommended for the engine.would it be alright to use

Theres most of your problem get some new fuel 20% is what you need you'll see a big difference.

the thing is though is that i was using my fresh 20%fuel i use in my car and it was a pain then i made the joke to my dad saying to try it but then he said to use it to get rid of it so i used it and it ran really well,much better than the 20%and it idled for much longer than the 20% but the reason i asked is that occasionally,when it came out the exhaust,it was a sort of milky colour but the fuel didnt go in the car that colour,it only came out that colour

How old is old with that 5% fuel??? If it's old old, it's more like .05%

 

[Extreme RC Mods]

As long as fuel isn't stored on the ground or direct sunlight and is air tight, it is good indefinitely. The biggest fuel killer is absorption of water, nitro doesn't absorb nearly as bad or as much as the alcohol. The milky colour could be moisture in the fuel, the residue should be clear oil, but it may be a little different colour then what you put in. There is a tuning guide in my signature, it may help you out.

 

[10 Gauge]

It's only good indefinitely if there's a completely hermetic seal on the bottle.

He said it got dark think all its good for is to keep metal from rusting the lowest nitro I've ever run in anything is 10%:

I've got another bit of good news,the other day,i accidently pulled my receiver battery wire and it broke I was gutted so since then (about a week ago) I haven't been using the car but just a minute ago I fixed the plug so tommorow (its 8:30pm here)I will get a new glow starter battery(wont charge)then I will use it and let you know how it is running.also,if I follow the tuning method in extreme rc mods signature,is there anyway I could do it without a temp gauge only I don't have one and I can't get one.one last thing,when i go top speed off road,the air filter keeps falling off,is there any way i can stop this(I've tried a cable tie but it didn't work)or shall I just get a new one

 

[mtaylortank]

did you try a good zipty
