I just bought a lews IM7 and am having a hard time handling backlash. Ive got the cap on where it needs to be but cant get the brake right. Any answers?

PS: im using monofilament 10# line

I assume you are talking about a combo. as the IM7 is the rods carbon rating. Would it be the Lew's Xfinity by chance?

 

If it is that reel has a dial on the side for the magnetic brakes. Set it to maximum and since you said the "cap" (tension control knob) is where it needs to be make a cast. If it backlashes it's defective and go exchange it. Some of those combos get broken from handling in the store.

 

If it doesn't backlash turn the side dial down one notch at a time until you get the max distance you can without backlashing.
