Throttle Spring 96 LT1

I have a 1996 Prostar 205 LT1, after pulling a rider or running at higher RPM after shifting to neutral the engine will rev to about 1500-2000 rpms. After looking closely it seems that the "throttle return spring" is weak. I have it rigged with a small bungee cord and slight tension to get me by for the weekend and it seems to work but still a little rough at shifting. It brings the throttle back to the stop point which is the idle. Can't find a replacement spring any where. Any thoughts or suggestions?

Thanks

T

Since the boat throttle is returning too well, wouldn't the throttle return spring be too strong? There are cable clamps available that put more friction on the throttle cable.

Well it returns fine out of throttle but when there is no load.. like in neutral- the engine revs. You can simple lift the hood and set it back to the idle position.

I apologize, I answered the question I thought you were asking without reading carefully. My throttle tends to creep towards lower RPMs when my hand isn't on it.

Here are some pics of the spring needed... you can see the little plastic tab sticking out doesnt even rest up against the linkage bar.

have you tried it without throttle cable? could be a sticky throttle cable.

Attached is the only picture I have in my phone on how mine seats. I think you just need to wind the spring another rotation before inserting into plastic tab.
