Anyone know the specs or a source for a replacement return spring on the Hot Shot foot throttle made by Bob's? I bought one 13 years ago and the return spring finally broke. The new Hot Shot on their site looks different; I think mine was a very close replica of the original T & H Hot Foot. Seems to have been about 4.75" long, stainless, but the strength of it seems much higher than the 4.50" springs that McMaster lists on its site. I got a spring from the hardware store to get it working, but would really like the correct one. I called Bob's and they have no springs. They also couldn't/wouldn't tell me the specs. Told me to call back in a couple of months because a shipment is coming in. Same old crap, nobody carries inventory anymore.

Would appreciate any input. Thanks.
