Tähistame teeninud ......Is it flat tappet cam? If so then I really hope you didnt ruined your camshaft...If that was first start and you let motor idle you ruined your camshaft Iam more than sure about it. NEVER let motor idle with new flat tappet cam!
Have you heard about camshaft "brake in" procedure?

Tähistame teeninud ......15min to idle, are you grazy!? You ruined your camshaft allready! Prepare to order new cam AND lifters and before fireing up motor with new camshaft read how you have to make "cam break-in" : http://4secondsflat.com/Hydraulic_lifter_cams.html
NEVER ALLOW ENGINE TO IDLE!!!

This shaft and lifters are not new, he was standing on this engine, but with a different crankshaft. I used this to substituted camshaft crankshaft, pistons and connecting rods.
I'm on this camshaft has traveled many many miles, I think that will happen to him all right.
