Cold morning start up problem

Check motor capacitor

Thanks - I've been back to this again yesterday and the settings have completely changed.
Now I cannot get the CO2 below 11.7% and I've had to drop the pressure from 125psi to 100psi. Doesn't matter what I do to the pump, or the air settings, it seems to have no effect at all.
Every time it starts up it stutters momentarily then fires with a big Whoomph.
I had the analyser gong from 12.3 to 11.7 and back again. It even went as high as 13 on one occasion.
If I can't sort it soon, I'll be fitting a new burner for him

What type of burner is on it, did you run it with the snorkel off to see what the co2 is at

It could be recycling flue gases. If it shudders on ingnition with abit of a boom it could be over aired . Sounds like a head scratcher.

Take a baffle out.

Some ideas, -
Disconnect any air snorkel.
or
Replace nozzle, as even a brand new nozzle could be faulty or get damaged
or
Check if air shutter is actually moving
Check air route including fan and to blast tube is all clear and no dead mouse, etc.
Consider possibility burner motor might be running slow, although unlikely.
Keep oil pressure to what it should be, - really best it is at the higher setting

I had a mouse break down. Autopsy report said "electrodes working well"

Sterling job!
Surprised a mouse could get into that Sterling burner.
The B11 burners are always a problem and just a large mouse trap

It's branded as Trianco but it looks very much like an RDB1 and there's no snorkel on it at all.

New nozzle at service around 6 weeks ago. Changed it again when I changed the pump. Nothing in the airways, Motor appears to be running well, and the air shutter look as though it's moving but I didn't take it apart to check so that might be the problem
