Before hopping up my 1990 CRESB 20 HP motor by boring out the intake, I had been on the hunt for a 30 HP carb. Seems like I had been looking for ages.

I got one in the mail today that I purchased on Ebay. The listing stated that it was a from a 1991 30 HP evinrude.

Well, I get it today and it doesn't match up with any 30 HP carbs from 1991. It doesn't have a low speed idle screw. It doesn't have a primer solenoid attachment on the float bowl.

So, what did I get?

Will it work with my motor?

How would I adjust the fuel air?

Looks to be a late 80s carb, just like on my '88 30 hp Johnson.
The slow speed idle needle is adjusted with the black knob.
This carb is setup for a manual primer.
All you need is the bowl to mount the electric primer solenoid.
I think the bowl from your old carb should fit?

edit: One thing I just noticed is the orifice plugs (#22) are different between the 20,25 and 30 hp.
So you should do a little research before swapping bowls. Sorry, but I'm not an expert here.

I've got the manual primer.

I just can't find a carb that doesn't have the normal screw in brass fitting for low speed idle.

I'll throw it on and try it out.

edit: I figured it out. It's an 88, not a 91. The low speed idle is set on the top orifice plug location on other years!
