Thanks Mark and Kelly,  I will try new plugs and see what happens, if it will remove the roughness.  I also raised the temp. by partly blocking the rad air flow.

Kelly,
 
I have at least 60-70 hrs on the Iridium plugs and they are performing flawlessly.  I pulled them out and took a look a few hours ago and they looked great, so I put them back in.  As far as I'm concerned, Iridiums are the only plugs I will use from here on.  This could change if I have to start burning 100LL.

Rino,
  Mark Steitle recently posted that he was using the Renesis plugs in his 3 rotor
20B and reported good service although I do not remember how many hours
he reported at that time...............Jump in here Mark and give us an update on
how these plugs are doing...............

How long do the sparkplugs should last on the Renesis engine.
My engine is starting to run rough and I suspect the plugs.
I have to say that it is also running too cold, it goes down to about 160 F (oil and water) when comming in for a landing which is usually 3500 rpm.  I have the NGK iridium plugs, lead RE7C and trail RE9B.
 
I am trying to warm up by blocking the radiators at the moment.  OAT  between 30 and 40 F.
I will have to build shutters to control the engine temp.
 
Last month the engine was too hot, now it is too cold.  I did modify the air ducts and change the oil rad for the original RX7 rad.
