Carbon Buildup
I have a 1987 n/a that has some issues. I have heard that when a rotary engine has a lot of carbon the car shakes and you lose a lot of power. Both of these things are happening to me and when I say the car shakes I mean the whole car shakes. I have had this problem for about 2 months now and just recently heard of this as a possibility. It would make sense that it has build up because I bought it from a dealer and the guy who sold it to the dealer told them it was a barn car, I was not told this until after I had the car home. If this is a problem let me know and let me know how to fix it and how hard it is to do.

I have done a cold compression test and got 90 on both rotors. I will try the oil.

I have seen about the water treatment and I thought it wasn't advised when there is a lot of buildup because it could get dislodged and do something to the housing or the rotors?

If you read about the process one of the things that can go wrong is the cat becomes clogged. You would normally use a gallon of water per rotor but you don't use the entire gallon at one time but parse it out to two portions so you're dividing up the cleaning process in two different intervals so as to reduce the chance of releasing too much carbon at one time.

have you searched for vacuum leaks? checked/confirmed timing?
water/steam cleaning won't hurt (at least, it shouldn't if you do it right), but there are other simpler things you should have probably looked at before you came to the conclusion that carbon is causing the symptoms you describe.
basically have you checked and/or changed all filters (particularly fuel) and ignition components?

What aspects of tuning it up are there?

Here's that link for posterity and any future searches....
Rotary Resurrection home of the budget rebuild.
If you don't find another obvious cause for the symptoms and want to try water ingestion I don't think it would harm anything either. It may not help, but it won't hurt. Distilled water for obvious reasons. Not sure if it's addressed in that link, but I'd do a quart or so at a time with a little rest in between, keeping an eye on the exhaust... which will get hot.
Where in Iowa are you btw?
