Hi
I just finished rebuilding a club members 74 TR6 that I had bored .060"
over due to cylinder wall damage.
The owner had the radiator cleaned out, provided a new water pump,
thermostat, temp sending unit and so on.
The car has a set of DGV Webers (downdraft) on it.
There are a couple of issues now with the engine I'm trying to sort out.
Engine runs on the warm side with the gauge between 1/2 and 3/4 some
excursions to 3/4 when left idling for a _long_ time. When the engine is
revved to 1,500-2,000 rpm it settles back down to 5/8ths on the gauge.
* I suspected a faulty replacement temp sending unit and
replaced it with one from my car and it brought the temp down
slightly.
* I also tried to burp the system by bleeding the air out at the
sending unit but I can't seem to get it out. When I remove the
sending unit there's just air.
* Any better methods of getting air out of the head?? Doesn't
seem to purge after thermal cycling the engine. New cap as well.
* The replacement thermostat was a 165 deg. I suspect that it's
higher than that. Can't measure actual coolant temp since I
broke my Temp Tester.
* My next step is to remove the thermostat.
Engine backfires through the carbs cold when when snapping the throttle
when the chokes are off and not quite warmed up. Not a problem at
operating temp/No backfires.
* Distributor is the vacuum retard type and the vacuum line is
disconnected.
* Base timing set at ~1deg BTDC
Any Ideas?
Thanks in Advance
