Constant misfire ??????
#58
(27-08-2024, 10:54 AM)Ruairidh Dunford Wrote: I had a misfire when the engine was hot, I eventually pinned it down to one valve spring that was 0.020" oversize on the diameter, as it heated up it touched the side of the block causing a miss. I got the bottom of it as I heard a squeak as it stopped, rotating the flywheel back and forth produced the squeak and it all became clear.

My own experience with needles that are too rich is that they can cause a spit a certain revs, is your car spitting or missing, hard to explain how they differ in words, but if I could hear it doing it...

Hi Ruairidh, just stripped carb and found a GC needle, this looks rich, as confirmed by 'mintylamb' !!! and sooty plugs. Found a BJ on fleabay that I just purchased, but will be looking at valvetrain by the w/end as want to use the car for a local meet, but spitting at higher revs seems to be the issue, just very hard to fathom out ???? and frustrating too !!!
