CB series giving multiple problems
I have a CB 150, serial number 01-28848. It was recently serviced - we replaced a CO2 sensor - but now the n2 value exceeds the set value (it just shoots up). The valve was replaced as well but the value still exceeds set value. I am now suspecting the sensor but think its going to be expensive replacing it (already spent a fortune replacing the CO2 one). Is there a way of cleaning the sensor? or fixing it?
