    Where's Tom?

    I was taking the impulse coupler off of one of my S4 mags on the Champ and well - I don't want to get into the details but, long story short, I need to get the spring back in the housing and I don't have no fancy Bendix spring winding tool. I've done this before when I was a kid but now I'm old and it scares me. I've already lost enough teeth.

    Is there a trick?

    Thanks, I got it. The actual "trick" was 9-2.8 step 5 (Figure 9-15) using a screwdriver to hold one and one half turns of the spring up so you can get the cam hub engaged. It's all coming back to me now :)
