Edited after some more work-
For starters, K3 DL1000 with 70k miles.
Did a valve check and new iridium plugs in preparation for a 3 week trip. All the valves were tight- glad I checked.
Will start but run rough. Will not idle unless I give it a little gas. Will pop / puff every couple of seconds from the front cylinder.
The front exhaust was not hot to the touch but the rear was.
Cam alignment questions seem to not be the issue anymore. Seems like the front cylinder is not firing.
And after adjusting valves, aligning per the manual
I have it tore apart again, checking the cams and alignment. All seems good.
Here is a video of it "running"
Spark issue? Timing issue? Electric? Vacuum?
I think I will start with spark and compression tomorrow.
Thank you in advance!
