[Healeys] update on shutdown issue

[Tom Felts]

I'm using the new floats, have a new 3ohm coil, and have changed the Pertronix to a new one. This is crazy----but after my last attempt by cleaning and oiling the baseplate of the distributor, she has sat at idle for a loooooong tie and has not shut down. I'm still shooting in the dark, I'll admit, and if she shuts down again I'll do a quick spark test.

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
