Cant try to remember what the B is, but TDC is Major Lifeless CENTRE for for timing. All 20V's, no matter if for the Coastline or highveld must have a btdc of ten deg. Meaning your inventory timing ought to be established at 10.

Getting readings within the O2 without the diagnostic port jumped will let you know what it is actually reading. This is an excellent diagnostic step.
Because all air for idling need to be coming from the ISCV? Also, Will be the fully shut TB obtained from modifying the linkages that connects the 4 throttles.
Why would the carbs being unsynched modify theAFR? Some cyls would run abundant an some lean but In case the O2 is Functioning then it can continue to common out to stoich.
In the event the engine fires, vacuum is applied to the throttle opener servo, and the rod retracts until finally it is actually away from the throttle arm for as long as the engine is jogging.
i have new blacktop mounts from Toyota NZ among other stuff so it really should get installed afterwards in the week ideally. the wiring is one area i set to the back burner however and now its time to finish... or merely megasquirt it if I get mad plenty of...

To get straightforward for any boosted application I'd Individually would throw it all out and suit a plenum with just one throttle - lighter, fewer to go wrong, neat but which is just me.
– Conversion notes: The spung tensioning system can be swapped on to some Blacktop but it also necessitates the swap of various other parts. In whole the sections expected from a Silvertop might be the oil pump, cam belt, cam belt rigidity pulley, tensioning spring, the steel put up equipped in to the block with the spring to loop over and And finally that the bottom and Center plastic belt addresses possibly be tailored or adjusted to that as applied with a Silvertop.
1a. "Thoroughly shut" is about through the throttle end screws on Every single ITB. Following that, not staying entirely shut is due to the incorrect setting on the linkage opening clearances. If you might eliminate the linkages to reduce them as
... the 4 sets of cam lobes are established at ninety deg aside. Fairly often the engine will end with two sets of valves partly open up, but it surely can be done for it to stop with a single set completely open and the Some others closed.
