Hi Manu cc I push oil into the cam ring when I get home. I've never tried fat.
If anyone here on the forum has used grease for the cam ring on 7-35.7-77.9-99 so tell us

OK, merci.
Je demande, car je suis en train de faire la révision du mien, et d'origine y a de la graisse blanche.
Et à chaque fois que je démonte un poussoir après un vol, de la graisse en sort avec la pression qui se créé dans le carter de distribution.
J'ai tout nettoyer, maintenant je sais pas si il faut remettre de la graisse, ou continuer à mettre de l'huile après chaque vol.
J'ai contacté UMS, mes pas de réponse.

How are you mounting the radial? I'm still trying to figure out how to mount my 7-90.
I'm sure this has been answered 1M times, but whats the grease coming from out of the radial near the pushrod base? There is a decent amount that comes out everytime I run it. Is it a defect or a feature??

Ziroli Stearman 87 inch
Next year, if the weather is good, my Stearman gets its maiden. The weather in the Netherlands is bad now. Many rain and low tempertures.
The Stearman has an Evo 7-77 radial, and runs very well. I am glad with this engine.

I have received tips on good carburetors for UMS / EVO 7-35. it is from OS 3.5cc for boats. which should fit without adapters

Hey TomWithout looking back through the whole thread, do you remember the aftermarket carb upgrade for the 7-77. Just wondering. I plan on running mine this summer. It runs fine but lacks power. Hope for a new year and look forward to much radial fun for all.

Carb issues
Hi guys, I'm having issues with my glow cdi converted evolution 7-77. Can't seem to get a stable top end with the original carb running on glow, also the main needle does not seem to do anything as running it at 3 turns yields the same result as on 5 turns out...
AAnyone else with this issue and do the OS carb really make a difference?
Appreciate any tips.

A new specific thread?
Hi all who are excited about the newer UMS Radials being distributed in the USA. I just bought a 115 from CH and have had it installed on a Phoenix Waco I bought flown prior but motor less when purchased. I would like to institute a new thread specific to these newer generation UMS engines. Sort of don't know how to do that actually.
Anybody interested?

UMS Radials
I did not know UMS produced a 5-cylinder 115 radial and having just looked on CH-Ignitions web site, I did not see it listed as an available engine. I'm interested, so I would like to know where you purchased this engine. Also, is your Waco the 63" 1:5 3/4 version?

I would be interested. Under gas engines just start a new thread. Maybe title "UMS new radial Engines". I have the new Gas 55cc, 100cc 5 cylinder and the new glow 35 cc 7 cylinder engines. The 100 cc is a near perfect engine when using the APS power fuel pump. The 55 cc 5 cylinder had a lousy carb. The Saito 90R3 carb worked way better on gas.. -Tom
