New Zenoah Carb Insulator- PLUS Installation Instructions

[bigrcr]

For those of you who have ever had problems with your carb insulator warping (no matter how carefully it has been installed) there is a new product that will take care of your problem.

The insulator is made by a guy name Johan Bruins and is really the ticket for the Zenoah motors. Most folks that have tried this adapter did so just to try it out...like me. Most had no prior problems and viewed the new insulator as just Bling :glasses2: .

The adapter (insulator) is made from machined aluminum and is sealed using Teflon gaskets. The motor side gasket is indexed into the adapter by a machined lip that holds the gasket into place. These gaskets provide an excellent seal and I can say no leakage occurs at these points now.

The performance difference is amazing to say the least. The motor idles and transitions smoothly, the needles are more predicable and there is no signs of vapor-lock using this adapter. I was quite happy even after the first flight as those little occasional burbles and inconsistencies were GONE!

All signs of any leakage on the intake sides that was just ignored previously are gone (a slight amount of oil residue).

I guess that the stock insulators have always been a problem (that was not realized) even when they were not warped as there had to be some amount of leakage going on. The carb has been suspect, but the real problem really seems to be that the insulator/gasket sealing surfaces have been leaking..

I won't use another Zenoah based motor without using one of these little gems!!

I have one of these and the quality is fantastic.
Very nice product.
They ship from Texas, Had mine in a few days

[ClayK]

I'll add it to my list of stuff to get... Tom, you and I will have to talk a lot of shop about Zenoah when I show up at the Precision Fly. Hope you will be ready.

OOOOHHHHHH purple bling! Yonk! Got me one. :smokin:

[flyinfool]

OK, I just ordered a purdy blue one too.

[CustomPC]

Would these make it easier to break-in and tune a new motor on a Spectra-G for a gasser newbie?

Ordering one anyway, just for the bling factor.

[bigrcr]

Yes as the needles are easier to "read" since the motor is being fed more reliably and consistently.

I have been in contact with Johan and am trying to iron out a deal to carry his insulators and if things work out i will make them an option on new motors. Peace, Toxic Al :twisted: :badair:

[Peter]

Dont have them as an option , make them a standard fitting ..... .. :noteworthy :noteworthy :noteworthy

[Toxic Al]

I could do that but , the part is not cheap and i don't want people think I am shoving it down there throats if they don't want it. If every one want these to come stk on the motors then if you guys don't mind give me a pole and I will consider it. Peace, Toxic Al :twisted: :badair:

[Peter]

Well ... I'm paying for one now; two actually , one for each heli ... would rather have had em fitted and not had any tuning worries at all!!

thats my 2c..... no its $119 AU delivered !!!!!

[Peter]

BTW... I see Rick's has these now too ....

[Peter]

Just fitted them to my machines , I cant believe the improvement ....... :noteworthy ..

I had one that was leaking , its now as clean as and sounds lots better too ....

the other "wasnt" leaking , but its now sounding nicer , and needed a slight tweak , so it appears to be sealing better too ..
I'm impressed .... and Johan's communications are brilliant too ....
:noteworthy :noteworthy :noteworthy :noteworthy :noteworthy

Cant recommmend this product highly enough ....

:D :D :D :D :D :D :D :D :D

[CustomPC]

I have mine but i'm still building my Spectra.

Johan's service is great. I got an email from him saying it was posted (and the tracking number) within hours of placing my order.
It arrived about 4-5 days later.

Quality looks fantastic.

[Toxic Al]

I have spoke with johan and I am putting in a large order and it will be available on my motors. It will be an option at this point so when you order a motor specify you want one and it will be installed prior to shipment. I expect to have them in a week or so. Peace, Toxic Al :twisted: :badair:

[CustomPC]

How tight should the screws be torqued when installing these?

Do you need to use locktite on the bolts or are the spring washers enough to prevent them from loosening.

[bigrcr]

Johna has sent me the installation instructions and they should be ready soon if they are not already shipping with the adapters.

Yes, use some lock-tite on the bolts.

John,

I've posted a new thread over in the Spectra-G forum asking which way to install the insulator and carb on a Spectra-G

Do you still use the carbon plate? If yes, where does the Teflon gasket go? between insulator and plate or plate and carb? And do you then still need to use a normal gasket on the other side of the carbon plate?

[bigrcr]

No. I don't still use the carbon plate on the Spectra-G. Do not use any paper gaskets at all, just use the Teflon gaskets that come with the adapter.

Here are the Instructions as promised for the Z-rc Carburetor Adapter!

Hi All,

I just found that i had inadvertently installed the outer gasket (between insulator and carb) backwards.

If installed this way, it actually looks correct but the small hole doesn't line up fully.

My symptoms were that the motor would start fine but required a higher than normal butterfly opening to idle properly. The motor would also quit easily.

As much as i'm embarrassed to admit my error, i thought i would post it here in case someone else made this simple mistake and is experiencing the same symptoms.

I stuck mine in yesterday! Even remember to record it! :smokin:

Does seem smoother.

Hi Custom PC,

Please dont be embarrassed as I too installed the gasket between the carb and insulator backwards once. What got my attention was that the edge of the teflon was not perfectly flush with the edge of the aluminum insulator. I disassembled the assy. and made the same discovery you did.
There are two ways to make sure this does not happen,one, once assembled, make sure the teflon is perfectly flush around the entire edge of the aluminum insulator. A second way is to pre fit the teflon on the insulator to make sure it is oriented properly. With the carb out of the way, the small radius next to the pulse hole is a good indication of proper orientation. Mark the edge of the teflon gasket and aluminum with a sharpie, then once assembled you can double check to make sure the marks line up. If you all deem it necessary, Ill see about updating the installation insructions to make sure this is not over looked.

Thanks for sharing Custom PC.


regards, Johan

I just ordered one and the instructons are really nice in the PDF above. I wish everyone would pay this much attention to detail.

[Hagar7]

Ordered mine yesterday, sounds like a winner
