Are the HRC springs visually different from the standard springs?

Trying to determine whats been done to the carbs on my trackbike, the extra 0.5 washers are there but the springs look identical to some spare standard springs i have. i dont have any HRC springs to compare them with.

as far as i remember the HRC from rick where shorter

Cheers royster, im sure they were different but its been a long time since i last changed a set

same here(i didn't change them but i was around when it was done) and i remember being shocked as i thought the springs would come and be big hefty bar stewarts and they really weren't....

If you can wait until tomorrow I'll show you the difference in the pair.
