Just a note to those who own a renix system. Clean the manifold air temp sensor now and then. It will clog up with gunk from the crankcase breather system causing very slow reaction. Sensor starts seeing manifold temp. rather than air temp. Sensor helps control fuel ratio mixture. Idle and pulling power will respond to this simple procedure.

 

I thought I was the only one who noticed that. Makes me wonder how many of them have been replaced that could have just been cleaned.

I moved all of mine to the air cleaner housing and now they don't get dirty anymore.
