Hi I have another question i d

Hi I have another question i droped my cylinders @ a fast idle about 1200 rpm on the flushers did not get any noticeable drop on #s 3 and 4 then i checked for fuel in the bowls and there was i then sprayed carb cleaner in the throat and she responded right away all cylinders jump 1/2 inch gap def gettin good spark!! Then i noticed no idle adjustment on the bottom two carbs at what rpm does the jets start pumping on 3 and 4 no oil injection just premixing. Where are they getting their lubrication from? mercs are a product im not all that familliar with even tho i graduated from MMI in orlando go figure ha ha
 
"This sounds like the 2 +

"This sounds like the 2 + 2 engine, idle jets only on 2 cyls and the other 2 kick in around 1500rpms. Post your serial number and someone with more knowledge with verify the engine, hp also."
