New T Maxx..cant start

[Chad Sheets]

Just about had her broke in today. Will not start. Glow plug "pulsates"
a good orange glow while turning over and testing against the head. The
fuel lines are nice and tight (no pressure escaping). The cylinder had
hydraulic locked a couple times, so I know the piston has a good seat to the
liner. Any ideas. All she does is spin and spin. I got a couple hits like
it wanted to start, and that was it. Other than those two hit, all it does
is crank over.

Thanks in advance.

Also went out and drained the fuel tank/lines, and removed the plug, then
turned the engine over for about 30 sec upside down. Blew everything off
nice and dry-refueled and same old same old...no start, just turns over.

It ain't your lawnmower.
The glow plug should do just that... GLOW, strong and steady... not pulsate.
Your glow igniter has two leads in there; the plug is already grounded.
Holding your glowplug against the head is not required.
Break-in settings are hard on glow plugs. It is not uncommon to go through
a couple of them during the break-in period.
Get yourself a few new glow plugs (you will want a few spares in your toolbox
anyway).
Put a fresh charge on your glow ignitor.
Install a fresh glow plug.
Re-set your high-end needle to the factory reccomended break-in setting...
THEN lean it about 1/4 turn before you try to re-start.
(I have found that some factory reccommended break-in settings are so rich...
that the engine wil not even run)

Make sure you got fuel JUST to the carb.
Spin her a few times, and if needed, cover the exhaust with your finger (while
the engine is turning over) to force some fuel into your carb.
I usually do this for only a couple revolutions at a time.
She should go for you.
If all else fails.... call Traxxas tech support, they're pretty good.
Good luck, and report back how it goes.

Holding the glow plug against the head is required with the EZ-start system,
built in glow igniter.

If it is just spinning and the motor is not turning over, then your one way
bearing is slipping. Take apart the EZ start and clean the one way bearing
and the shaft it goes on with a degreaser (i.e. carb cleaner, nitro spray)
and replace.
This is a common problem with Traxxas.
I have seen guys drill a tiny hole in the top of the EZ start casing and in
the bottom, just to spray degreaser in there.

Thank god I still work my engines in the traditional way, never let me down
yet, but I agree, the glow on the plug should be steady, very red / orange
glow, almost white glow is perfect....if it is pulsating it means the
battery charge is dying.

Another way of priming is remove the air filter from the carb and hold your
finger on the intake, turn over the engine 2 or 3 times by whatever means it
uses (pullstart or whatever) and then replace filter, with correct needle
setting this will now start perfectly.

I watched my nephew start his car perfectly more than 10 times the other day
in the time it took to get a Savage started twice (and the savage was using
a rotostart too..!!!) The only reason my nephew had to start his car so many
times is because he keeps spinning it doing do-nuts and this usually ends up
cutting out the engine but not always.........he is due some new tyres
though as he is running on slicks now....!!! They were knobblies until a
couple of weeks ago...!!!

Regards..............Mark.

It is funny that I had a similar problem last week with my Savie.
With the plug removed does the engine turn over like normal? With
compression it does not? Be sure to turn the engine in the correct direction
on this next question. Can you turn the engine over with the flywheel while
the plug is in?
This sure sounds like a one way bearing problem similar to what I had last
week. Remove the engine and take off the starting mechanism and turn the
engine (in correct direction) using the one way bearing (by hand grip) with
the plug in and if it slips at all and does not turn the engine over you
have a bad one way bearing. Remove, replace and race! Hope this helps ;-)

I'd check for good fuel flow (back the HSN all the way out), head
bolts, header bolts, etc.

If he's using the stock ezstart he will have to ground it to get
continuity.

[much good advice snipped]

Or the batt is jammed in the 5280 control box backwards.
Or the starter motor is wired backwards.

And relube.

More on the Pro15 ezstart than on the 2.5.

First thing is first get rid of the garbage on board glow ignitor. It will cause you nothing but problems. If your battery gets slightly low your engine will no longer start. This was really a poor design by traxxas. I personally perfer pull start (I don't like lugging the battery pack around everywhere) but the ez start is ok as well. Get yourself a rechargable glow starter (The last a lot longer than the starter that run off a standard alkaline battery, I personally have had great luck with Hot Shot) now remove your glow plug put it in a freshy charged glow starter make sure all the coils are glowing a nice orange color, also make sure the coils are consistant in shape. It is normal for the top portion, or even the entire top coil to not glow. Once you have confirmed your glowplug is in good shape install it back in the engine. Place your finger over the exhaust and bump the engine over a few times. Watch the fuel in the fuel line until it reaches the carb. At the point turn the engine over 1 or 2 more times, NOT MORE! Now put your new glow starter on the glow plug and fire your Maxx up. Like mentioned above it is not uncommon to eat a couple glow plugs in the break in process. But after your engine is broken in the glow plug should last a long time if you tune your engine correctly. I had a glow plug last me over 6 months trouble free.

I do carry a spare ignitor as a backup.

That is something of an exaggeration. I have heard of failures but
have not had one of mine fail ever. And I treat them pretty roughly.

Every time I use it it starts the model; therefore one can expect
something other than 100% problems.


> if your battery gets slightly low

There is a resistor in there to neck the voltage on that circuit down
to 1.5vdc. If the batt is quite low the ignitor site may go too low.

You can test it by runnig the batt down, then running a voltmeter
inline with the blue wire. Anything lower than 1.2-1.3vdc may not
glow the GP enough.

Yeah, all the integrated electric starters by all the other
manufacturers are much better. Oh, wait...
