7.4 running rich
 

Hi all. Got my 7.4 running with a rebuild kit in the weber/edelbrock carb. I set the floats to spec. Starts on first crank every time. Seems to be a little rich though, as I can smell it a little. Are the marine engines supposed to be a little on the rich side?

Hey Paul ,
Hook up a vacuum gauge to a vacuum port on the base of your Weber.
Adjust the idle/air screws til you have optimum vacuum , that should solve it for ya. :wink_thumbup:

Ok Larry. I'll have to go to a plug on my intake to get some vac. My weber has no ports on it

It should still work fine Paul
Just make sure you keep the screws out the same number of turns , or at least very close.

Re: 7.4 running rich
 

Gotcha. I prolly need to check the plugs and my timing too. I think that's the only two things I haven't looked at on this thing. I better get on the ball- weather is warming up quick here

Just great day for the ride. She started her 21st year of service yesterday. My passengers yesterday could have cared less.

We've had a few low 80's days already. Humid as all get out. Mosquitos and wasps are already out, some are big enough to carry a small dog away

I'll take the heat.
You guys keep the humidity and bugs! :rolling_laugh:

Re: 7.4 running rich
 

It gets like that every summer here, so it's either stay inside or go to the lake for relief. I prefer the latter

No humidity here, it's a dry heat!

Re: 7.4 running rich
 

No humidity or mosquitoes here either. It's too frickin' cold and there is 3" of new snow on the ground this morning.... :shakehead:

Re: 7.4 running rich
 

Yuk, Mikey. I was talking the other day about how warm it was, then the weatherman made a liar out of me. Cold front came through yesterday morning with nasty storms and temps dropped into the 40's by noon. Crazy Texas weather. On the bright side- no bugs were out!

Yep, Sunday & Monday we hit a high of 21c (69f) and today our high is -3c (26f) and tomorrow -5c (23f). By Thursday we're supposed to be back up to +12c (54f). Go figure.... :shakehead:
