David,
How hot is it outside?
I have never experienced this problem on my 72. But I did install
Hitachi SU HS6 carbs to avoid the diaphram problems with the ZS 175s. My
idle is constant around 800 RPM no matter how cold or hot it is outside.
Once I got the engine all set up last year, it has run like I would
expect a rebuilt engine with new carbs and distributor.
Have you checked your diaphrams? Oil in the dampers? Timing? P.lug
condition?
Bob
BTW, I use the midgrade 89 octane in all my Triumphs. On 05/26/2012
