I just got a adjustable timing chain. Its a Cloyes "Hex-adjust". It looked good in the summit catalog, but now that I have it I'm wondering if anyone has had any problems wiht the little button slipping and causing the timing to change? Nothing seems to hold that little button in place. ANy feedback appreciated.

We race dirt mods and use them in all our motors.Never had a problem yet.

ok thanks. I feel better.
