I also own a DuraStool (Heh) M-ST.. It is not so bad after you***around
with it a few times. If you are getting air bubbles in yer fuel line (from the tank
to the carb). There are a few reasons, NOT including holes in the fuel line. Since
holes in the fuel line are very unlikely. If you run your fuel line around the the
outer side of the engine (the side with the recoil starter), you will most likely
heat up the fuel line badly from the head/sink, then some more at the barrel
or tuned pipe if you put one on. Heating up the fuel line will cause the line to
expand and get softer, and cause backflow (air bubbles). Cheapest upgrade
for the fuel area of this truck is to get a cheap, inline fuel filter (only a
of bucks). Run a short line from the bottom of the tank to the filter and zip-strap
the filter to the support rod that runs from the trans to the pan infront of the
servo mount. Then run a line from the filter to the carb. Make sure you adjust
the direction of the *** on the fuel intake of the carb to point the other way.
This keeps line away from heat, and the fly wheel as well. And the filter will
catch any ***you get in the tank during some dirty runs.
Some other common problems with the ST is the Idle Set***or (ISS).
It seems to be flaky on almost ALL ST's.. If you set it, and fire up the
truck and let it idle, it idles fine, almost indefinately. Then you go burn the
thing around a track for a few minutes and stop to fill up the tank and it
just dies (like the idle speed has changed, you let off the gas and it dies).
The ISS basically screws itself back in from throttling on and off/braking.
Get the***where you want it and lock-tight it, or use something to
prevent it from screwing itself back in. (Will need to re-adjust when/if
you change fuel types. I run 15% 100% SYN).
Some other tips for this truck from experience are as follows ->
Instead of changing the shock-oil, replace the coils instead with
stiffer ones. No need to change the shock-oil on these trucks. Stiff
coils work great. Leave the front ones alone, they are good enough
and can be adjusted within reasonable limits.
Install a tuned-pipe (MIP Stinger is perfect for these trucks) but the
bolts included with the pipe will not be long enough, so you can torq
in your original ST barrel bolts with some lock tight and it will stay
forever, or drill the holes on the pipe bigger and use long bolts with
nuts (and ofcourse some lock-tight).
Install bearings for the front and rear wheels, this is a definate must,
those crap-ass bushings will wear out very fast and make yer wheels
flop all over the place and you will lose alot of control.
Replace the front and rear suspension arms with metal (titanium) ones,
the front ones seem to break too damn easy.
Also, if you flip the truck over lots and bend / kink / then break your
antenna often. Here is what you do. Cut the antenna tube (not the wire)
shorter, to about 9 inches. Run the wire up through it and down the
side. Then heat a few layers of shrink tube over it all with a blow dryer,
nice and tight. I have folded the antenna in half many times and its
still straight and not broken, after over WAY too many rolls..
If you have any questions about your Maximum ST, feel free to email
me.. Its not my truck of choice, but have been working with it for
over a month (hard) and trying to improve it to be more of what it
