possible sheared woodruff key?

[chevyboy13]

well in my previous post i was having poping and misfiring and i still am. the im almost positive that i have a sheared woodruff key now. it still runs pretty damn good but its missing. i also noticed its getting hot alooot faster and a decent amount hotter. sound like a sheared woodruff key? does anyone have a picture of one? thanks guys.

What makes you so sure it's getting hotter?

Methinks it is time for a leak down test, sounds like an air leak creating a lean mixture.

With a sheared woodruff key, you would be lucky if it even ran at all. I agree, do a leak down test on that bad boy and you will probably find a leak somewhere.

Here is a sheared key, notice it cleanly sheared off on the shaft of the crank. This little bugger was a pain to get off.

If its not running smooth and misfiring it could very well be a sheared key. I bought a blaster a while back and couldn't figure out why it ran like crap turns out it had no key at all. Its super easy to check. Just get a flywheel puller and check the condition of the key.
