I have a slight problem of the car wanting to stall when I let the clutch in, if I do not give it some revs.
which seems very odd for an engine that should have a lot of initial torque. Once driving it appear to pull ok.
It is an XK120 with the timing set at 10 BTDC with vacuum and about 700RPM, HD8 Carbs with UO needles, Jets set about 1/16 to 1/8th down. It has the Rob Beere special mild camshaft designed for running with SU carbs. It has an electronic ignition sold by Denis Welch, which has the gentle curve from 10 degrees up to a max of 34 degrees at 4,000 RPM. It does have a slightly lightened Flywheel and first gear ratio is 2.95 on the Tremec T5 gearbox. I have checked the cam timing, ignition timing,
tried the jets up and down. Manifold reads about 14”. Also if I let the engine idle with the temp at 80C it soon climbs up to over 90c unless I put the electric fan on. This is with ambient air temp of 20-25c.
Is there anything obvious I am missing or not tried. Car does not use oil or water !!! Leaks a bit oil.
