Roggie Posted November 12, 2011 Report Posted November 12, 2011 I bought a coolhead today and looked at the domes and it looks like someone crossed off a number and engraved 21 next to it. How can I measure these domes to see what size they really are? Quote

How can I measure these domes to see what size they really are? Each dome should be stamped with the dome size. Does the other one have 21 on it? Quote

sprinklerman Posted November 13, 2011 Report Posted November 13, 2011 Take out the domes, put a spark plug in them, then use a large syringe ( or a burette if you have one) to fill with liquid and record the amount it holds. You really should use a flat plate sealed with vasoline or grease ,with a hole in it , to seal it up. Quote
