100hp mercury carbs

[red neck yot club]

i am rebuilding the carbs on my 1988 mercury 100hp inline 4... they are not delivering any fuel although there is fuel going to them... and i was wondering if anyone knows the stock adjuster screw settings or the sinking procedure thanks

Re: 100hp mercury carbs

If your 100hp motor's serial number is within the below ranges, then the spec for the idle mixture screws is "1 3/4 turns" out. You really need a shop manual to find out what all the link and sync steps are. An OEM shop manual is the best. There are many steps and a manual is essential to avoid messing up the settings and possibly blowing up the motor... in my opinion.​
