[Healeys] Running Problem and assistance from the list

Hello Brian

 

Some years back the BN3 started to run poorly, not inconsistent to the
symptoms you have described.

 

After much trial and error I was getting nowhere. 

 

It then occurred to me to go back to how it was when the car left the DHMC,
and I removed the inline fuel filter. It ran perfectly!

 

I had swapped the filter during the trial and error. 

 

Conclusion! The engine was starving for fuel due to the original pump not
being able to push it through or the filter(s) were restricting the fuel.

 

Also the Healey Duncan is exactly how it left the DHMC.

 

Best wishes

First I would like to thank everyone for their suggestions. This list
continues to amaze me and I am thankful to be a member.

Unfortunately I have tried all suggestions that were mentioned. 

Just for clarification, I detached the fuel line from the pumps and blew it
back into the tank. I did not blow trough the pumps.  Next time I'll
remember to remove the gas cap though. It sounded like I could have blown up
the gas tank (I didn't).  I had checked the needles on the vacuum pistons
and they were solid in them. The only thing I have not done yet is to blow
out the passages between float ball and the carb body. The quantity of fuel
coming out of the line at the carbs when the ignition was turned on was
quite significant. There was no air nor was there any debris in the fuel .

I have repaired cars that had identical running problems and in my mind it
was a fuel starvation  or delivery problem. I  just hope I haven't been
mislead and focussing on a fuel issue when it could be a bad coil or
electronic ignition issue. I will be putting everything back together and
moving to the ignition side next. There has to be a solution, all I have to
do is find it!

Thanks all.

Brian Drab
