Backfiring help

David,

Does this have a Ducellier distributor fitted?
If so, try disconnecting the vacuum advance line from the carb.
This style of dist. is reknowned for the vac. advance unit failing, causing the symptoms you describe.
Solution ??
Fit a new distributor PLE143 for $129.00

Thank you all. Probably next week. And of course, I will try to keep everyone posted on the problem!

I believe you just described life in general with a Series Rover

the great part of these trucks is that you learn a lot about how an engine works and what to look for next time..
