Thread: Comp 3 Keyway Timing Set

Tweet

Rookie question. I have the comp 3 keyway timing set. Thanks to forum members like Richard, I know what the 'square,' 'circle,' and 'triangle,' slots on the crank sprocket represent. Here's my question: My keyway on the crankshaft is square. What's funny is that all 3 different keyways on the sprocket will easily fit the square crankshaft key. Is that how its intended to be or do I need to install a particular keyway (more circular?) on the crankshaft? I want to set at the rounded keyway for straight up timing but did not know if I can/or will be ok just sliding the rounded sprocket keyway over the square crankshaft key. As you'll notice in the picture, I think I have the 'rounded keyway' on sprocket over the crank keyway. Thanks
