Re:TR6- Thermo. Ports

Ken-

Thanks for the instructions and diagram (where do those thermo ports go?)
!  Re-hooked and turned the car over no problem, after sitting for nine
months.  It took four tries.  

Once I got it going there was this clanking sound coming from the engine!
 Sounded like loud knocking!? The clanking/knocking increases and
decreases with engine rev.

Could the fuel be causing this (sitting for nine months)...bad fuel? 
Valves making this noise? Any ideas?  Thanks.
