Has anyone come across a way to have a remote needle valve on a moki 1.8 engine? i have the engine cowled in and would like to be able to adjust the carb without removing the cowl. thanks for any suggestions!

just put an extension on the needle.

Hello!
Never ever extend your highspeed needle ......a long highspeed needle will give problems to your carb setting ...vibrations you know!
On my airplanes were I can't use the regular high speed needle I have cut off the old needle at the carb, leaving only the fuelnipple and sweat soldered a thin tin plate over the hole ( I still use the fuel nipple though).
I then use a another needle placed in a more convinient place where the needle is easy to reach ( like at the rear of the engine cowl, between the cowl and the fuselage,10-15cm from the carb). I mount the new needle on a piece of steel plate or epoxyglass plate bolted right yo the fuselage.

Thanks guys for your feedback. I have done the extension route a few times on needles that come straight out the side and are held in with a set screw on the arm. The Moki is a different challenge cuz it comes back at a strange angle and doesn't have this set-screw arrangement. The engine is under a small removable hatch so i'll proably end up just keeping this hatch off until i get the needle adjusted, then pop in on before flight.

you can cut a slot in the needle head for a screwdriver, or any number of things. Personaly, i dont like remote needles. Im not familiar with a moki needle, but a slot would work fine like the good ole days. good luck.

If there's no set screw on the main needle, you could try tapping it and screw in a short hex nut. This way you can use a hex driver (ball type) to set the mixture.

If tapping the needle is not an option, soldering wil do the job too...

I'm not a fan of remote needles either...

I just contacted Conley (Perry Carburators) about using their remote needle on a Moki 2.1. They said it would work ... hope they are correct because I will be trying one on both a P-51 and a Extra 300. They are also modifying their In-Flight Mixture control to work with a Saito 180 for me .... hope this works also ... I ordered two.

You may want to ask around about a remote needle setup.

In past issues of model magazines, I've seen mention of a dowel with a piece of large fuel tubing attached to the end of it. When you want to adjust the needle, you stuff the fuel tubing over the needle valve, and turn the needle with the dowel from outside the cowl. The idea is simply a glorified nut driver.

How about this?? Turn the stock needle valve out about 5 turns from closed and then install a remote valve in the fuel line and use it to adjust the mixture. I've done this before on a cowled engine and it worked great! I did use some tubing on the stock needle to keep it from turning and I wanted to make sure that it was sealing and not sucking air. If you ever want to go back to stock, no problem. And no boggered up carb either. Try it, it really works!
