update on tr6 idling high. triple carb, mild cam, etc
Here's what we did this morning:
1. found what looked like a vacuum port in the bottom of the middle carb and
blocked it off. it is likely once upon a time connected to the dizzy, which
no longer has a vacuum connection.
2. blocked off all three vacuum ports on the top right of all three carbs.
these were connected to the valve cover, brake booster, and vapor recovery
canister.
3. the car started, and idled very nicely at around 1200. but then as it
warmed up, the idle increased back up to around 2500
4. checked the position of the pistons in the 3 carbs. the front and center
carb were more or less sitting at bottom, but the rear carb (by the scuttle)
the piston was noticeably raised. blocking off that carb completely killed
the engine. slowly blocking it off lowered the rpms, the more we blocked it.
what next?
