We, walterolin and I, were trying to adjust the valve on my newly rebuilt engine tonight and we couldnt get the intake valve on #1 to loosen. We found TDC, 0 mark on the fan and #1 exhaust valve adjusted just fine. The problem is that I loosened the screw completely on the intake valve and I still could not get the feeler gage in there and it wouldnt budge (slightly rattle) when we tried to shake it by hand. Its REALLY tight.
After that we turned the engine so that the valve was for sure all the way open, and nothing. The screw is all the way backed out and its completely tight no matter what position it is in. What could cause this? My engine builder told me that he adjusted all of them to .006, so it obviously was correct at some point. At a loss here.. THanks |

As I said, if you're using the fan or distributor to determine TDC, keep in mind that dizzys can be reclocked a and the fan maybe have been disassembled by someone previously and put back wrong.

I saw your post, thanks, and thats one reason that we confirmed with the Krusty method. The fan, (and my previous mark on the underside of the flywheel), seems to be correct with the #1 valve positions (confirmed by SLITS above), but the dizzy is now exactly 90 degress off from its TDC mark. Knowing this, we can now proceed.
