air intake screen on JW,s and Evinrude 3026

[crosbyman]

is the small screen in front of the carb (behind the front part of the side air silencer) necessary for air flow/input control or was it just for bug control ???

my $20 Evinrude 3026 is missing the screen 🙁

It’s there for a reason but I’m not sure why. Maybe to help the motor run better by dampening the pulses or to help stop fuel from spraying into the silencer. Whatever it is, I’ve ran the motors with and without it and can’t really notice any difference.

I can’t tell any difference either. Except on models with a fixed high speed jet. You can’t adjust to compensate for the missing screen.

well I guess that settles it. I have the 2 needles to play with so off with screen

thanks .. now if only I had a few more boats the run all these motors that are piling up…. 🙄

Could it have been meant as a backfire flame arrestor? Didn’t the previous model type Evinrudes catch on fire sometimes?

Long live American manufacturing!

An old time mech once explained to me that it was necessary to create a partial choke situation. Not sure why they couldn’t be adjusted out, but that’s what he said. I’ve always left them in.

It was put in when some of the November ’51 pilot production run engines (sent to Florida) had problems coming off an idle. It is supposed to improve intermediate speed performance. OMC used to listen to it’s cultomers. . . 😆
