RE: Official HPI MT2 Thread
It is running the standard HPI engine. I have not tried a new glow plug but I just checked the one that is in there. The whole thing seems to glow pretty good apart from the very tip ( the part that touches the rim).
I have tried factory settings for a bit. Car was slow as hell but still cut out after about 30 seconds. It does not have a fuel filter fitted but I will check the pipes to make sure there is no blockage in them.
Keep the ideas coming please.
Many thanks
Adam

It sounds like either to much fuel is being dumped into the carb or a lack of fuel. If you are running at factory settings it SHOULD run but will run very rich (lots of fuel).
Have you tried a new glow plug? Do you have a fuel filter? Make sure all the fuel lines are not clogged. Same with your fuel tank. What engine are you running?

Well seems as everyone is complaining that it is so quiet around here, you wont mind helping me out before my MT2 lands up in the skip. I'll try to cover everything but if you need any more info just holla.
The problem is that I just can not keep it running for long. It starts up fine and idles fine, but it just keeps on cutting out on me. It sometimes runs ok for a few minutes, but sometimes you can hardly pull off without it cutting out. It just completely bogs and dies. Sometimes it happens when the car is at WOT, and sometimes when I am just driving slow. I have reset the needles back to stock and tried tuning again but it just seems to happen all the time. I bought the car used so I dont know too much about how much use the engine has had or anything.
Basically, I am very new to Nitro so what I am really after is just as many ideas that I can check as possible until I find the fault. I have read that lack of compression can cause this. How do I check for compression??
Any help would be much appreciated as I am really regretting getting into nitro cars at all now, and would really love to get this thing running nice cos it is loadsa fun when it is running!!!!
Cheers

RE: Official HPI MT2 Thread
it will cut out because the factory settings are so rich just turn the high speed needle in an eighth (leaner)at a time and watch your performance improve!!!

RE: Official HPI MT2 Thread
yes the factory settings are rich but it should run. If he is getting to start and idle it should stay running.
The only other thing I can think of is that your motor might have an air leak. I've heard those motors leak a lot. I personally have had pretty good luck with them.
Do you know how old the motor is and how much fuel has been run through it?
Do you have your idle set properly? Does it cut out at high speed or while idling or braking?

RE: Official HPI MT2 Thread
I have tried tuning it from the factory settings and yes...it does fly.....but not for long!!!!
I have the idle set so it stays running nice??? I presume this is right?? It does not cut out while braking. Just at random times. Sometime it is when it is WOT and sometimes when I am just going slow. Where would be the most possible pace to have an air leak and how do I check for it??

RE: Official HPI MT2 Thread
If it's cutting out like that I would say either an air leak or somehow the fuel isn't getting to your motor.
An air leak is most likely the seals in your carb. I've never had the problem so I can't tell you how to find or fix it. If you search the forum for T15 air leak you should find it. A member called 46u has sealed a few motors that had the problem. you might want to PM him.
As for the motor not getting fuel. It could be your tank too. After it stalls. Is it easy to start back up?

Yes it starts back up no problems. Suppose thats the fuel blockage idea out of the window. I did just check all the tank and fuel lines anyway but they all seem fine. Damn this bloody car is doing my nut in!!!!
And cheers for all the help mate. Much appreciated.

RE: Official HPI MT2 Thread
it will mean you have a air leak. Most likely in your primer. I had the same trouble when i had the t-15 [:@] i added the 100cc tank and increased the fuel lines length (so if i flip it wont cut out) and i never had any problems since. I now have a lrp z18s pro engine, and what a great engine it is, I have not had to tune it for 3 months

RE: Official HPI MT2 Thread
Well the primer leaks fuel everywhere so there may well be air getting in there. Would this be a big enough problem to make the car stall though???

RE: Official HPI MT2 Thread
yes, because if there is air in the fuel line it will cause your engine to lean out and rev higher plus this will cause the engine to over heat. Primers suck, scrap it and get a 100cc primerless one.

RE: Official HPI MT2 Thread
hey adam
i removed my primer on my 75cc tank.
what you have to do is cut off the shaft as close to the tank as you can.
the rest of the primer will fall into the tank. then you just have to fish out the
parts from inside the tank. i glued a screw in the hole where the primer used to come out
of the tank. when i washed out the tank in water and checked to leaks. i got well over 3 gallons
thur my tank without any problems.

RE: Official HPI MT2 Thread
Hi Guys,
I had a problem getting my 18ss to fire up for a while now, the story so far.
replaced head/heat sink with purple hpi varient due to threads to seat glow plug cross threading
replaced tank fuel due to old one cracking
Initialy the pull start was tight and jerky but after some help form here I identified that I had left a shim off the head and I have now replaced that.
The car now wont fire up.
The compression feels fine without glow heater inplace
With glow heater inplace it becomes harder to pull and makes a noice like it is firing once but not turning over.
does anyone have any ideas what could be the cause of this, I was guessing an airleak from the replacment head but I have used some gasket seal and still no change.
many thanks in anticipation of your help
Neal.

RE: Official HPI MT2 Thread
Hey guys, i was thinking of getting the LRP Z18S, then on the other side of my head was the o.s cv-r. Im pretty sure they are both more powerfull and better than the .18ss but how would the LRP compare to the OS? I do still have the TZ sitting around with a 20t clutch bell and 47 spur and it is very tempting. DECISIONS DECISIONS...

RE: Official HPI MT2 Thread
Could my idle speed affect how well the car runs and be the cause of my car stalling??? I have now removed the primer from the tank (car is starting a lot better now) and I adjusted the idle speed so it idles faster but then had to shorten the servo arm to stop the car flying off. It seems to be running seet as a nut now although I have only run it out in the garden so can not get up to any speed. My brakes were sticking on too so that is now sorted aswell. Try to get out this afternoon and see if it will stay running now.
