Ladies and Gentlemen,

My friend and I are prepping a 1979 Triumph TR7 for ITB racing and have come across an issue. The automatic choke fitted to the later TR7 model years is prone to failure and on our car has failed. Would it be permissible to replace the automatic choke with a manual choke? The GCR only touches on removal of the choke system, and I would expect the answer to be no based on the "all other components must remain stock" rule, but I'd like clarification.

Best,
GeoSTI
