Default vspec carb on extech .24

So I am fed up with the stock card on my Trinity Extech .24. I spend more time chasing a tune that driving it feels like. Anyways, want to know if anyone has tried am OS Speed carb on this engine. I figured this would end my inconsisent tuning issues.

And yes I have sealed the factory carb and checked for airleaks.

Put a Novarossi carb on it.. I have seen many people do it and they love it. The nova carb is better anyways.. you can find them on ebay for 70 or so.

This is the one you want..

it was my extech, we could never get that thing to run right with the extech carb, just didnt seem snappy or anything then we put an vspec carb on it, that thing came a live, more power everywhere and alot more responsive.

and 21, 24 and i think 28s all have the same carbs.

Should work fine. I would replace the thermo insulator if your is
crushed or cracked where the pinch bolt rides.

You will want to go back to something close to factory needle
settings.

High Speed- 3 turns out from fully closed.

Low speed- Flush with the ball link.

Mixture control valve- Should be flush with the carb body with
the slot at 12oclock then turned in to 2oclock. For a larger .24
I would leave it at 12oclock.
