I almost made the mistake of adding the P 51 Mustang to the applications list. However as I did what would be expected of anyone, was further reading. This article is absolutely correct in showing that this version of the Merlin Engine was not a major application to the P 51 Mustang and actually mentions later the "Licensed" version that was used in the P 51. Therefore this page is accurate in NOT listing the P 51 Mustang and I hope others will continue to read further into this before trying to change or even arguing the facts. My Thanks to the contributors who made sure the exact details of this common error appear on this page. JericVgilbert (talk) 18:34, 5 July 2020 (UTC)Reply

In the box we have “Number built 149,659”. In the text we have “after 160,000 engines had been delivered”. At least one of these is wrong. JDAWiseman (talk) 19:31, 15 October 2020 (UTC)Reply
Footnote 10 shows the breakdown of production numbers, I believe somebody edited the figure in the lead to include 18,000 plus Packard V-1650 engines, this is the subject of another article, also adding off topic text. I have amended the lead to nearer the wording that was reviewed and accepted at WP:FA review. Nimbus(Cumulusnimbusfloats by)20:10, 15 October 2020 (UTC)Reply
There is a Wikipedia writing guideline to round numbers in the lead, the capacity is also rounded (1,649 to 1,650 cubic inches). 08:35, 16 October 2020 (UTC)

I think that is actually explained wrong here. Spitfiŕe carb had two(three) problems under non-positive G. At 0G it will starve. At some negative G it will flood and at major negative G it will flood enough to kill the engine and possibly even fluid lock it so it wont even restart. The idea of Shilling Orifice was to limit the fuel flow to what maximum power needed, ie. to limit the "damage" of flooding the engine to where it would only sputter but continue running. The actual fix for the starvation and flooding problems only came with better carbs.
In float carbs the float controls the amount of fuel in the chamber by shutting down the fuel flow when the fuel in the chamber floats the float high enough to close the incoming fuel with a needle. Now if G is negative the float will float to the bottom and the chamber is filled with fuel straight from the fuel line, which then sprays directly out of the chamber into the carb throat at fuel line pressure. —Preceding unsigned comment added by 185.185.170.85 (talk) 12:42, 29 September 2025 (UTC)Reply
