[Healeys] update on shutdown issue

Thu Sep 21 06:13:05 MDT 2023

If the engine starts and idles nicely—and there’s a nice fat spark at the plugs—but won’t rev, it sounds like a distributor advance sping(s) is broken or faulty in some other way. Might consider rebuilding or replacing the distributor (I’d choose a Mallory dual point over the Pertronix dist, and Pertronix makes a module for that as well). If the car runs well but conks out on the road after it warms up, then restarts and repeats, it’s that stupid little ground wire inside. Someone else mentioned a blocked gas cap breather, which is also quite easy to check. Rust in the gas tank? Could cause the engine to run well and then stop, which is a good reason to use a clear fuel filter. But this really sounds like a dist problem …

Might the brass floats also have pinholes, causing them to fill with fuel and preventing them from rising as they should? The new nitro phyll floats solve that issue. If not, I’d suspect the distributor (internal ground wire or advence weights). Might also be worth buying another Pertronix module and a 3-ohm coil (always smart to have a spare along anyway) and see if it isn’t one of those. Still, it sounds more and more like an advance problem if the engine won’t reverse.

 Which type/brand of pump do you have? I've seen pumps, both points and SS, do some unexplainable things. Another thought: something in the tank that intermittently blocks the pickup. We bought a used tank for our BN2 and experienced erratic behavior from the engine; my dad finally tracked it down to a pinhole leak near where the pickup was soldered to the tank. Dad surmised the flux used to facilitate the soldering eventually etched the hole (the tank was otherwise in good shape).

  Since having the car towed home I have checked all connections in the ignition system, pulled the distributor base plate out and cleaned it--the the two pieces were very tight.  I have let her run in the garage for long periods of time and she has not shut down again so I haven't been able to check spark.  
  When it did shut down, it wouldn't take long before she would start again then shut down.  Then start, then shut down.   
  I know my trial and error method wasn't the best approach, but without being able to check spark it seemed appropriate to change out components.   
  Tell me if my analysis is correct on this.  I thought it might be a fuel supply issue.  So---I pulled the float bowl covers and all was ok there--also pulled and cleaned the carbs.  If the float bowl jets were stuck in a closed position it would get no gas and eventually shut down---but---both would have to stick so each carb wouldn't get gas.  this seems like an unlikely condition. 
  If they were stock in the open position it would be dumping gas out of the overflow tubes---so, again, unlikely since it would still run.  I have already changed fuel filter and blew out the line.  The pump pumps normally and each time I pulled the float bowl caps, they have been full of gas.  So--I have basically ruled out fuel starvation as a cause.     in the garage she sits and purrs forever with no shutdown------so, as I mentioned, I can't ch spark
