Abstract
A coil-over throttle return spring device mounts onto the exterior of the carburetor and allows the user to adjust the throttle tension without having to remove the device from the carburetor. The throttle tension is adjusted by moving the ring along the length of the body to lengthen or shorten the spring. A coil-over throttle return spring device kit comprises the device and a bracket and hardware used to easily mount onto various size carburetors. The bracket and hardware allows for adjustability depending on the size of the engine and length of cables. A method of installing a coil-over throttle return spring device kit onto a carburetor and a method of adjusting the throttle tension.
Claims20
A coil-over throttle return spring device comprising:
- a rod having a first mounting end and a second mounting end;
- a body located between the first mounting end and the second mounting end, and coaxially surrounding the rod;
- an adjuster ring surrounding the body and configured to threadedly rotate along a length of the body;
- and
- a throttle spring coaxially surrounding the body and rod, and loaded between the adjuster ring and a cap such that a first end of the spring abuts against the adjuster ring and a second end of the spring abuts against the cap;
- wherein a compression of the spring is adjustable by rotating the adjuster ring along the body to increase or decrease a length of the spring.
A coil-over throttle return spring device kit comprising:
- a throttle return spring device having a rod with a first mounting end and a second mounting end;
- a body located between the first mounting end and the second mounting end, and coaxially surrounding the rod;
- an adjuster ring surrounding the body and configured to threadedly rotate along a length of the body;
- and
- a throttle spring coaxially surrounding the body and rod and loaded between the adjuster ring and a cap such that a first end of the spring abuts against the adjuster ring and a second end of the spring abuts against the cap;
- wherein a compression of the spring is adjustable by rotating the adjuster ring along the body to increase or decrease a length of the spring;
- and
- a bracket for attaching the first mounting end to an intake manifold of an engine, the bracket comprising
- a platform having an upper side and a lower side and an opening for connecting the platform to the intake manifold;
- wherein the first mounting end connects to the upperside of the platform and the second mounting end connects to a throttle arm.
