[DeTomaso] Hot Start Issue

[Mikael]

Difficulty starting when hot only is due to a combination of bad wiring
(usually ground, experienced it myself) and too advanced ignition. Vapor
lock would leave the engine running freely and not ignite.

A hi-torque starter can sometimes solve this situation, but is compensating
for a problem instead of correcting it.

And if you're in a situation where the engine will hardly turn when hot due
to it working against the too early ignition, you can always start it and
get out of that embarrassing moment by pressing the accelerator all the way
down. Tthis clears the fuel after a second or two, and no more fuel is drawn
since the vacuum is gone. So no resistance from the too early ignition. When
the starter then gets the engine up to normal cranking speed, release the
throttle slowly and it will start. No need for an ignition cut switch. 


Mvh/Regards
Mikael

Sounds like you are too advanced.

There are -two- things you need to pay attention to when re-installing a
distributor.
- Position of the rotor
- position of the vacuum advance.

When putting the dizzy into the hole, the rotor is going to turn as it goes
in.  This is because both the dizzy gear and the gear on the cam are angled.
So if you thought you had lined up the rotor, then pressed the housing all
the way in, the rotor would then be off by one tooth.  
Something to consider.

If you are pinging at low speed, it sounds like you are way too advanced.
