I have questions concerning a BT7 tricarb.
While tuning the car, it was noticed the two rear jet heads were at
about the same level but the front jet head was considerably higher
(all were below the bottom of the Venturi). It is my understanding
the height of the seat is related to float height setting and
lean/rich jet adjustment.
Should I recheck the float levels to see if something is amiss and
adjust so the jet bearing seats are more uniform before I tune the carbs?
The carbs sometimes spit petrol, while cold (common issue I believe)
and upon acceleration when the engine is hot. Is this an issue
related to valve timing and/or rocker clearance? I think spitting
back fuel can be caused by a too lean condition.
Could the valves be staying open too long? I have a Denis Welch road
cam which is similar to a BJ8. Per DW, the rocker clearance is set to
.015 cold.
Needing clues to fine tune the healey.
TIA
