The idle screw is set to a 1mm gap, but when the linkage is connected it cannot close the carb in its current setup. in order for the carb to be closed, the linkage arm has to bend down as you see in the third picture.

Stormbringer Posted February 21, 2021 Share Posted February 21, 2021 ahh ok mate maybe the linkage to the carb is to short or the bit that goes to the carb has slipped round a bit and everything needs to move a 1/4 turn round been long time since i messed with nitros mate Quote Link to comment Share on other sites More sharing options...

The previous owner must have messed up the linkage i think, but i'm just not sure exactly what hes done. There are hardly any pictures of this truck to see what it normally looks like or was like from the factory :P Quote Link to comment Share on other sites More sharing options...
Stormbringer Posted February 21, 2021 Share Posted February 21, 2021 the black arm onto the carb i think that is on a square shaft into carb . you could slacken the nut and see if you can turn the arm 90 degrees then move rest of linkage round and see if that helps Quote Link to comment Share on other sites More sharing options...

I think its because the arms on mine dont move in line with each other the carb is moving in the vertical axis up and down, whereas the linkage arm is moving in the horizontal axis and the little arm between them isnt long enough to make up the difference. 13 minutes ago, Stormbringer said: the black arm onto the carb i think that is on a square shaft into carb . you could slacken the nut and see if you can turn the arm 90 degrees then move rest of linkage round and see if that helps i'll go take another look at it now :) Quote Link to comment Share on other sites More sharing options...
Stormbringer Posted February 21, 2021 Share Posted February 21, 2021 it definately looks wrong mate and thinking the servo arm carb linkage is on should rotate 90 degrees but then carb linkage needs rotate as well sorry i am not more clear or certain about this 1 Quote Link to comment Share on other sites More sharing options...
Crazy L Posted March 2, 2021 Share Posted March 2, 2021 Hi guys I had a quick search but couldn't find an owners thread, so I created one, and now I've seen this one, which is well old. So thought I'd post here instead I've had my MGT since 2004, ragged it to death, raced it at Maxbashing. Then when the engine (yup, still original .21) got tired some years later, I converted it to brushless and 6s. It was undriveable. Then the 6s went up and took the shell and esc with it, and stained everything in a horrible smokeyness, including a patio slab. Then about 5 years ago I found a set of OE wheels and tyres for a bargain, and a piston/liner set, and that's where I got to.....UNTIL NOW. Exhaust found, put back on, engine warmed and fired up to run it in. 4 tanks later I have dug out a servo and ordered a body and paint, and a steering servo.

Crazy L Posted March 2, 2021 Share Posted March 2, 2021 Continuing on frommy previous post, I finished running the engine in. Finished the shell, and the results are as follows: 2 Quote Link to comment Share on other sites More sharing options...
Crazy L Posted March 2, 2021 Share Posted March 2, 2021 I would like to add also, which I forgot to mention in my vids, is that although the engine is the stock .21, but wears a Thunder Tiger .28 head, I had to modify the head to fit, as the pcd of the mounting holes are larger on the .28.

It doesn't seems right to me as everything is bending all over the place and the carb doesn't close to a normal idle gap. Yeah, that isn't right surely. Looking at the 1st photo, is that with the throttle closed? if so, I would have thought the 90 degree arm you have needs to be another 45 degrees anticlockwise, so it is parallel with the carb. Looks wrong as you like. 1 Quote Link to comment Share on other sites More sharing options...

Looks wrong as you like. Its fine I got it fixed a while ago now. The arm on the carb needed rotating round so the arm was in the same position as the carb opening. It had been turned round another 45 degrees or so. 🙂 1 Quote Link to comment Share on other sites More sharing options...
