Glenn---A couple of things could be done that might help the cold start.
One would be to richen up the mixture (if the plugs look like they could stand
it). You could also just do a trial adjustment, since it's quick and easy.
The other would be to advance the spark timing to as much as 14 deg. BTDC at
idle speeds at 800rpm. Some cams really like more timing than what the book
calls for.
A friend with a TR6 in upper Idaho has no problem starting his engine with NO
choke on a stock engine. I suspect he's running on the rich side, tho.
Lastly would be to raise the CR to at least 9.0:1. Again, the cam and trips you
have do well with more compression, and timing!

Subject: [6pack] Choke Cable
With the recent thread on the 6 pack email list, I have a couple of
questions for the wisdom of the collective groups.
Just installed a triple stromberg (Good setup) on a rebuilt early TR6
engine with a cam this past fall. The only problem I have is during
starting, it takes more than two carbs to start the beast. I need a
third cable to connect to the center carb to get it going. after that it
runs to problem.
Any one else had this issue? I have the front and rear carbs on the
cable. The center carb is not contributing to the starting event.
All three carbs were extensively rebuilt including throttle shafts and
seals.
Any ideas out there??
Thanks in advance
