Takes longer to start when engine is hot...

[Fiat88]

My car starts really fast (love the gear reduction starter), but when I go for a drive sometimes the car takes much more cranking to get it to start again. Trying to think what could be the problem, could it be something with the ignition timing?

IIRC, you have a 32/36 DFEV carb? What type of fuel pump do you have, electric or mechanical? One starting point would be to get the fuel filter with the return port so the gas can circulate, it relieves pressure on the pump if its electric and circulates the gas to keep it cooler and prevent boiling.

Also if the 32/36 carb is installed direclty on the manifold it will soak up a lot of heat, get a spacer.

Magnetic pickup? When mine went it acted like that. Drive the car a little then stopped somewhere. Get back in the car no start. Wait a little while then fired right back up. Can't tell you how long it took to figure that one out.

could be the module, but my bet is that the engine is over-rich at that point

Yes, I have 32/36 DFEV with 1800 intake manifold. I'm using a electric fuel pump and do have a 1" spacer under the carb. I thought a return line wasn't really needed for the DFEV, and since I put new fuel lines in I didn't run a return line but I guess I will have to.
I replaced the control module like 2-3 years ago and haven't driven the car that much so I really doubt thats bad. I replaced the magnetic pickup awhile ago and did notice the same thing last summer. Could it also be my timing is too advanced?

is your choke set to open after its warm?

Will have to check after I get my new muffler installed. Too loud to drive it now, and just brought it out of long hibernation from winter and working on it. Will keep you updated.
