I've replaced EZ starter to pull Starter. do I need to do anything else??

A glow warmer or hot shot.  And thick skin on your tugging fingers.

LOL...
Start drinking very heavily.
The beer-lifting exercise will help build your tugging arm strength, and the
alcohol will ease the pain and frustration of those hard-cold-starts.
You could just get a starter box, but that wouldn't be as much fun.
(Besides, a starter box won't work with some Traxxas vehicles, like the
T-Maxx.)

I'm curious why you made this change?  I have one pull start car and want to
change it to a drill starter as soon as possible.

I've heard of people getting rid of all the starter stuff entirely but I
think that more for performance concerns.  That I can understand.

Usually it's about weight reduction.

Sometimes it's a weight reduction issue.
With Traxxas vehicles it's usually a reliability issue.
The electric (never easy) EZ start is a peice of crap. The one-ways slip all
the time, the gears strip, the glow wires are faulty, the batteries may be too
low to turn the engine over... it goes on and on.
Most newbies like their EZ starters, till they fail for the first time (mine
did within a month) then they start looking for  alternatives.
Most go with a pull start.
If a starter box won't work with the vehicle (T-Maxx) ...that's what I would
do.
The "Yank Eliminator" (electric drill starter) works, but you are exposing your
crankshaft, and rear bearings to all kinds of dirt... not good.
GT Grand Prix 00 - 26 Jan 2004 01:57 GMT
In regards to getting dirt on the crankshaft seal, I have a one way bearing
problem on my RC10Gt. I got a starter and donut for starting. To solve the dirt
problem on the crankshaft, strip the pull start housing, seal the pull cord
hole with RTV, and install it. It works great having an empty housing to keep
out dirt.

Yep, that's what ya gotta do.
Thanks for sending the tip.
I see that yank eliminator as a recipe for short engine life.
A starter box, or a bump starter is the best answer.
Justin Mahn - 26 Jan 2004 13:31 GMT
For TRX .15 engines, the sealed backplate bolts on to the pull-start engine.
Otherwise, just get a backplate and grind the starter nub off of the
conn-rod knob.

The pro 15 ez start was adequate at best.  The 2.5 ez start is pretty
robust.

Doesn't sound like a starter problem to me.

If you had a failure within a month I assume you called Traxxas and
got warranty replacement?

Glad to hear that they decided to make an improved version.
I hope it lasts as long as the engine lasts.  If it doesn't, what good is it?

Well, you're right it isn't.
It's just one of the added hassles you get with the EZ start. If you go out to
run, and your batteries fail you... game over (for the day at least.)
Heck my starter box battery can fail too, but I can "jump" the starter box from
my car battery till I get it re-charged.

Nope.
After watching a number of friends throw their EZ starts in the trash,
punctuating thier speech with a good dose of.....
("&*%@Gd,Mf,Pos,Gd,Sht%#@%")
I just went to a pull start.
After that, a starter box.

I know the thing was under warranty, but shipping it back to Traxxas and
waiting another 2 weeks (or more) seemed like a waste of time. Especially when
I wasn't thrilled with the EZ start in the first place.
My LHS had a pull-start unit in stock.
I was back up-n-runnin' in under an hour.

What good is a glow plug if it doesn't last as long as the engine?  Or
tires that don't last forever?

Models from the major players are made of components that can be
easily replaced.  I don't expect anything to last forever.

And I carry extra batts in my case.

That's your call.  I always take advantage of warranties when they are
available.

Charlie Durand - 26 Jan 2004 18:39 GMT
If any part of a car were to fail in the first month I'd be getting it
replaced under the warranty.

I've never had a Traxxas but I have the HPI roto-start setup and like it.
It's way better than pull-starters.  I've never tried a starter box.  Is
there an advantage of using a starter box over the roto-start type setups?

Agreed, UNLESS it's a part you didn't want on your car anyway.

Perhaps the biggest disadvantage of these *on-board* electric start systems, is
the fact that there is no (immediate) way of telling if your engine is flooded.
If you over-prime, or otherwise flood an engine, it becomes "Hydro-Locked".
Once that happens, it will not turn over till you get all the extra fuel outta
the cylinder. With a starter box, the rubber starter wheel will stall, strain,
or slip if it tries to spin a flooded engine.
With a pull start, you can *feel* it when an engine is getting flooded.
With an EZ, or roto start, the first thing that happens is the gears will just
strip out.
Additionally, using a starter box, you can lose all that extra weight, and
mount the engine much lower on the chassis, thereby lowering your center of
gravity.
Lower CG = much better handling.
You also get rid of one extra thing that needs maintenance, and a set of
batteries that need charging all the time.
With the glo-plug connected through the EZ start, as soon as you hit the start
button, power is taken from your glow plug, making the engine that much harder
to start.
I always recommend that people using their EZ start, get rid of that glow plug
wire, and start using a standard glow plug ignitor.
If you like your roto starter, keep using it.
When they work, they truly are convenient.
Just pay close attention not to flood your engine.

Go to ANY track where they are runnin' nitro cars and trucks. You won't find
many "roto starts",  "EZ" starts, or pull-starts there.

The 2.5 version of the EZ Start has logic that senses when the
engine is flooded and it automatically cuts the motor-cranking
circuit.

For this reason stripped gears and smoked starter motors are
practically unheard of on the 2.5 EZ Start.

True.

Now that sounds like a major improvement.
    However... how do you spin the engine again to remove the excess fuel?

I hope the answer is that the EZ start somehow senses that there is no longer
any restriction, and it allows you to spin the engine a couple times to remove
the excess fuel.
If that's the case... way to go Traxxas.

No matter what though, I will still always love my starter box.
But... if you've got a T-Maxx, where you can't use a starter box, the EZ start
seems like the next best thing... if it works like you say.

Yeah, after the GP is pulled the sensor detects the decrease in load
and spins the engine over.  Works really well.

> No matter what though, I will still always love my starter box.

Absolutely.  Starter boxes are a really great tool; many of my friends
use them and are very happy.
