Ello all, i've had my marder about 2 years much fun had so far !!! Until 2 weeks ago that is, took it out for run no probs til i went to start this weekend all it wants to do is run flat chat. Was told it could be the fail safe so got new one, re-set the carb to factory settings but made no difference.
Any help/advice to try and sort this out would be much appreciated.
 
Sorry chaps, to run flat chat means at full throttle!!! tried resetting failsafe made no difference. Tried it without the failsafe still the same out come. Reset the throttle servo made no difference!!!
 
Does it run without the electronics off and the trottle in the idle position?
If it still runs WOT with the electronics off its a motor issue.

If it runs fine its an elecronics issue.

Which of the above works?? :helpsmilie:

What type of radio set up, failsafe, and servos are you running? Any photos?
 
problem

I think this is the problem of your car,,,,,,,,,,

Carburettor throtle valve shaft wants by sand often go badly to turn.
This problem occurs much to the control side of the carb, not on the side of the spring.
The throtle valve go continues to hang, and is no longer in the neutral position.
If the damage to the shaft has been done, you can continue cleaning this throtle valve shaft.
The sand is so back again.


This is my solution for this problem.
There will be more solutions ,,,,,,,,

I have made a small bush from nylon with a recess for the O-ring.
The bush is just free of carburettor, and is precisely tailored from the O-ring to the carburettor lever.
The o-ring remains nicely into his place.
So you have no longer problems with sand between the valve shaft again.
