Gas Boiler Downsizing by Burner Removal

in Gas Heating
So I have a 40 year old natural gas boiler installed in a multi-zone system. Works nicely but now that the house is well insulated the boiler is 50% over sized.
I only need 98,000 BTU and the boiler net is 158,000 BTU.
The boiler short cycles and I currently can not afford a new one.
How crazy is it to remove two of the six burners, plug them off and block the airway at these locations, thereby reducing the input and likely reducing the short cycling?
Anyone have some thoughts?
Thanks in advance.

not the 1st....
time this has been asked.... No boiler Mfg will approve this. There create some cold spots in the boiler and create sooting issues and then venting issues. You may be better adding a reset control to get more out of what you have.0 -
Not a good
idea ever it will actually cost you more to operate and the efficiency will be cut in half.
I have actually done testing on this concept and the figures do not lie.
That plus the fact is you are drastically increasing the possibilty of very high carbon monoxide production.0
