I bought this throttle return spring kit for my 4500 series carb, and it fits like a glove! The quality is impressive, and the response is much better than I expected. I’ve put a few hundred miles on it now, and no issues at all. Would recommend to others!

Easy installation and great performance
Really like this throttle return spring kit from Moroso. It was super easy to install on my 4500 series carb, and the throttle action is so smooth now. If you’re looking for something that works without hassle, this is it!

Disappointed with the fit
Unfortunately, this Moroso spring kit didn’t fit my setup as I had hoped. It worked with the King Demon carb but felt a bit loose. I had to modify it, which was annoying. Can’t say it’s a bad product, but be prepared for some adjustments.

Sturdy and Reliable Spring Kit
Installed this Moroso throttle return spring kit in my 4500 series carb, and I’m really happy with it. The springs feel solid and work just as expected. It fits perfectly, and my throttle response has noticeably improved. Definitely a good buy for anyone upgrading their setup!

Good value, but minor issue
The Moroso spring kit does the job well enough. It fits my King Demon carb and works as described, but I wish the instructions were a bit clearer. I had to play around with the setup to get it just right. Still, it’s a solid kit for the price!
