Mobile is what I was looking for. Auto zone was the only one with local stock. Any non-devil folks you'd recommend? O'riely, advance and Napa are the big ones. There is supposed to be a car quest but I can't find it.

Apparently Madge has decided that reverse is no longer supported. Feels like the stick is stuck on the gate. Hoping it is just the outer/inner tube being disconnected. That's not to bad to fix. Other common cause involves opening trans and finding little pieces all over. Which doesn't seem bad unless the little pieces used to be big pieces. Symptoms point to big pieces all being intact.

Shift gate issue was my last similar happening. Fixed it through the speedo gear hole.

Reading through some online stuff I recalled pushing Madge with engine off but in first gear. Seems that makes a mess of some kind for rev. Put back in first and rolled opposite direction. Rev is now available.

One win for me.

need some help from ... the old UK car guys. I think that means Arie.


Here's the riddle.


MadGe starts up fine. Runs all day till you shut her off hot. Will start right back up but will then stall about 1-10 minutes into running. Just dies off. Like she's out of gas. When attempting to refire will cough like trying to start but no go. If I wait till she is cold I can start her right up and drive all day again. Last night that took about 90mins in the heat down here.


My thoughts are about fuel flow and boiling fuel before the carb. And one have a better diagnostic than "put in an electric fuel pump"?

check all grounds.. always the first thing with British and any old shit..
 
vapor lock is real...  how is your fuel line routed?

bad coil will be my guess...  but don't just throw parts at it...

coil is new in Jan. pretty sure that's not the problem


fuel line in this mess is a mess. everything runs over the exhaust manifold. I've been suspecting vapor lock but can't really figure out how to check for that.


one thing i did find was that my coolant was way low. I normally only check the overflow which never changes. I finally popped the top off the steel reservoir this afternoon to prep for a flush and it was less than quarter full. the overflow is 100% full so I clearly have a problem with feeding back into the system from overflow. I did change the oil ... 4 weeks ago... nice and black. New oil is still clear.

new does not mean good
especially with electrical...  coils can get heat soaked and fail prematurely...

vapor lock is my bet. electric fuel pump before the engine compartment would probably fix that unless it's real bad. I'm assuming block-mounted mechanical pump, so there's fuel line under vacuum in the engine compartment?

Could try some heat wrap on both sides of the equasion but that's really what it sounds like from here.

Paul, there's a fuel pump in a box that came with Madge. Looks "used" but newer than what's on the engine. Did you change the pump?
