Thank you

I haven't had much time to be on here lately. How the this build coming along?

 

[Ochana25]

Engine is in just trying to setup this push pull throttle need some help lol

 

[hotrodrob]

Ah linkage adjustments! Lol...start with zero on the tx, keep the screw out of the servo horn and keep moving it around the spline until you find a good enough position, every time you've moved it check operation, once you've found the spot you can then fine tune the linkage, adjust the grub screws first before using the trim dial

 

[Ochana25]

Here's a pic of the throttle but it doesn't seem like it's pushing in and out good without effort

 

[Ochana25]

Here's a another pic

 

[hotrodrob]

So your saying that something seems like it's tight?...if so then the servo horn is probably slightly pinned against the servo

 

[Ochana25]

Everytime I manually move the servo where the arrow is the red part that's circled the whole thing turns instead of the throttle pushing. In

Linkage adjustments are always a PITA! LOL

 

[hotrodrob]

It's not supposed to push in its supposed to pull out, the position it's in now should be the idle position with no brakes, when brakes are applied there needs to be no pressure at all on the throttle link, the spring should just compress like halve way or so when full breaks are on, if your on the breaks and the carb is actually moveing you will wind up with a busted carb, should check for tightness of the carb pinch bolt while your at it,...

Linkage adjustments are always a PITA! LOL

X2 for sure.... Getting the throttle to pull just right and the brake to pull just right and not close the throttle 100% during is such a joy, its my favorite part of the fun!

 

[Ochana25]

Is there anyway to stop the carb from moving the whole thing just turns

 

[hotrodrob]

You must not have read my post too well huh, lol

 

[Ochana25]

Ohh apologize just saw that lol Kk I got that tight sorry

 

[hotrodrob]

Did you also check for any binding like I asked?..you should be able to slide a piece of paper underneath your servo horn,if it doesn't then there is a definite bind there and you will need to shim it up with the perfect size washer on top of the servo spline, I like to file down the horn itself

 

[Ochana25]

Ahhhh no I will so that soon and update you

I thought this build was gonna be peanuts lol fml

 

[Nitro4910]

It is peanuts, setting up the linkage is always the nut buster of any build.
The linkage needs to be setup right, and operate smoothly or it will no end of headaches.
Below is 3 pages of direct pull settup's.

You need to loosen the carbs pinch bolt and straiten the carb out, so the slide pulls straight out in relation the the servo are pull.
You can also loosen the slide arms grub screw so you can can rotate it to the needed position.

 

[Snook Man]

Linkages are easy if you think it through.

As in the pic Nitro posted, you need to rotate the throttle arm on the slide valve approx 180 degrees (that will give you better alignment/angle with the servo horn) install the horn on the servo like in the pic (you want to pull the brake, not push it) then install the throttle linkage slider on the underside of the horn and you should be good to go with a few adjustments.
