My '74 1.8 normally runs beautifully but with our present 90 degree F ambient temps it runs hot and won't idle.
Temp gauge is just short of the red zone. (Next time I will get NHS to put numbers on the gauges.) Thermostat works - checked with hot air gun. Flaps are opening Warm air guides installed Tried enriching idle mixture by screwing in air bypass screw to max - no effect Would appreciate help from the brains trust Thanks David Brisbane, Australia |

I haven't checked fuel pressure but I have relocated fuel pump to the front using later model mounting. I expect the temp of the pump is not an issue
I have a fuel pressure gauge installed and will check this . Thanks The car starts and idles no problem at normal temp but won't idle when oil temp climbs just short of the red. That is, only when it is quite hot. It is a 911 style gauge using standard taco plate mounted temp sender. NHS restored the gauge and I sent them the sender to calibrate the gauge. Thanks |
