Hello everyone, thank you in advance for your assistance.

I bought a Kyosho Ultima GP Type R, I know is an old model, I got it with a Dynamite .12 engine, the Chasis has a plastic piece that goes over the engine from the transmission between the head and the carb.

The problem is that the carb needle hits the plastic piece and at the "closed" position if I look inside the carb it has a huge gap (about 1/3 of the intake), I haven't start the engine untill I am sure, but I suspect this will give me some troubles.

Do you know if I can reposition the needle to avoid it from hitting that bar? Is this common in a nitro engine?

Thank you all.






In the picture you will see that the niddle is touching the plastic piece but the carb is still open over 3 mm, like 1/3 open.

Thanks again

just loosen the LSN housing and move the throttle arm a bit so the barrel closes all the way and retighten the LSN housing. that should do ya good.
