I would maybe try 3 esr springs and 2 stocks. If that doesn't hold all esr springs should hold it. If not try adding some weight to your lock up arms

I use cheap clutchs. Never had any problems with them, and use stock springs and my 77hp prox doesn't slip at all.I also use atf type f oil. Esr springs are very hard to pull, they are stiff like cr500.

Cheap clutches?? What kind cork style? ATF type f oil... Hows that work? Standard transmission oil?

I had good luck with ATF as well... The only disadvantage, is it dirties very fast.
