The SPCR website was confusing because I couldn't determine the manufacturer. I contacted a spark plug supplier and like most, took the Torch F7TC cross reference to be a NGK BP7ES or the Iridium update of NGK BPR7EIX.

I purchased the NGK BPR7EIX but after more research, decided that the BP6ES or NGK BPR6EIX was a more suitable replacement as the 6.5HP is a Honda clone.

Anyway, what I have noticed is the engine starts as before but on being turned off even before getting warm, will start using 1/2 or no choke whereas the F7TC always required full choke.

On running with NGK BPR6EIX, I've also noted that the burnt petrol fumes aren't as strong.

Currently using 91 but may change to 95 to see if any difference.
