How do you compress the valve springs with the valve spring compressor part # K-D 2078? I am following the article in the Resources tab DIY, but when I connect the compressor and start turning it, it pulls the spring upwards and strats to compress at the top part instead of pushing the spring down towrds the block. I'm afraid that I may rip the spring out of the block if I keep going. Anyone have any thoughts on this?
