I started the topic because it morphed from an earlier one re correct spark plugs and has had me chasing a backfire in my KR.
So in summary:
Engine starts, idles and cruises fine but it backfires when accelerating harder than just cruising.
Car was running fine until i had it stored in a workshop for 3 years slowly getting some work done when it developed a backfire once it was started.
Had the carby rebuilt
Changed points, condenser and coil, set timing, checked number of spark plugs and they’re fine no sign of wear or fouling and the problem is still there.
Could be a vacuum leak causing engine to run to lean
Tilt away was fixed by changing the relay but now the relay is working but the tilt away wont tilt back so I’m thinking there’s a vacuum problem in the system which could be related back to the backfire.
A couple of guys on the forum have offered some assistance which is much appreciated, thanks Shelbydoug and 1967 eight barrel
So this is the current position, I’m going to chase down a vacuum leak as my next step,
If anyone else has had a similar issue your feedback would be appreciated by me and also to assist for anyone else who may experience the same issue in the future.
