Edelbrock 1410 Throttle Return Spring Issue

[StevNimrod]

I'm in the process of putting a 383 together and have gone from a 650 cfm carb (EDL 1409) to a 750 cfm (EDL 1410).

On the new carb install the throttle return spring gets hit by one of the linkages on the side of the carb.

Anyone have this setup and problem or have seen it and can recommend a fix?

Ayuh,... Boats rarely use a throttle return spring,... It's Cable controlled....
The Cable pushes the carb linkage to idle...

Ditch the Spring...

Hey! I like my spring...

You don't need it cause of the cable. I use one on mine though. The long straight end goes to the carb linkage(bottom back hole) and the spring end goes to the cable bracket. Mine is only a single spring.

I'm sure it's a great spring, the value of it is???

None....
I have noticed it helps maintain the idle speed though.
Sarcasm doesn't travel well on the internet eh?
I just reused it cause it was on the original motor.

The spring is a good safety feature in case the cable end pops off, or the ball stud on the throttle shaft end plate isn't solidly fixed (I've seen where they're braized on and the solder fails and they pop off.

No spring = no engine control if cable pops off, or ball stud comes off or cable clamps (at engine or handle end) come loose.

Spring = engine drops to idle if any of the above happens.

Call me paranoid, but I find that stuff like that happens right when you're making fine throttle adjustments, like trying to pick up a moorage in a crowded anchorage, or maneuvering around the marina.

Try using other holes in the throttle connection plate. For example, if the spring is in a hole above the pivot point on the plate and anchored toward the rear of the motor, try switching to a hole on the underside of the pivot point (if there is one) and lead the other end forward. Always test with the engine off - disconnect the throttle cable, look down the carb throats and be sure that the spring pulls the throttle plates closed - not wide open.
