 &50 Sohc with Carrilo rods and 836cc pistons.

PLEASE, can anyone help with setting up the FDP 315.
With # 1 piston TDC and its tappets set to 0.050
I read the following on the deg wheel.

@ 53 deg BBDC the Exhaust Valve opens.
@ 39 deg ATDC the Exhaust valve closes. (supposed to be 23 deg)

@ 23 deg BTDC the Inlet valve opens
@ 69 deg ADBC the Inlet valve closes. (Supposed to be 53 deg)

What am I doing wrong.

PLEASE HELP

hi, sorry typo dp 315

[MRieck]

Looks like the cam needs to be advanced

[754]

Tappets are set at .050.
 Is the .050not how far the valve moves..then you check the degrees?

Hi Man,
your cam is retarded............how much   39 -23 = 16 then divide by 2 = 8 degrees retarded  ( cos exh is biggest number)

I would advance the cam by 10 degrees so its 2 deg advanced.  How ? slot the cam sprocket or redrill the holes random and see if you get lucky      well at least put some thought into it with a protractor and try for 10 deg with hole centres 
ciao johno

-Maybe different valve train lash?
I had to tight the valv adj screws until it almost lifted the valve to overcome the play in valve train and achieve correct readings.
After that I adjusted the valve lash to running lash and measured what I got and equal lobe centers
