1985 FJ60 Can this be done? I am feeling the need for High Altitude Compensation. I have a NonUSA carb that has been serving me well. It does not have the air intake ports on the top of the carb for an HAC system. The only Vacuum ports are down near the base (3) all with slightly different vacuum personalities. The NonUS carb does appear to have the circuits for the HAC air intake but the ports seem to be plugged? Can these plugs be knocked out to insert ports? As a side note, still NonUS carb related, the fuel cut solenoid may need replacement (consistent hesitation and about 1,600 RPM) The Non USA has only one wire on its solenoid (the US have 2 wires) does any one have a PN or source for this? Thanks in Advance, Kevin R.
