 I have this engine running on a stand and it starts immediately and idles well, but is does backfire through the exhaust when the RPMs increase.
When I changed the timing belt I ended up with a very slight misalignment in the can pulley marks when the crank pulley is at TDC as can be seen in the attached photo.
Having never seen this or any 907 engine run, I'm not sure whether exact alignment is to be expected, or whether some small misalignment like I have is normal.
Moving the belt by a single tooth results in far more adjustment than I would need, but perhaps some amount of fiddling could get there.
Thoughts?
