rear cylinder misfiring help

[tfburke3]

Was it ever running good?
did you check the ignition timing of each cylinder?If say the front( #2) cylinder is timed with rear #1 mag cam shoe the timing would be right only for the front timed cylinder.
When I had my 34 apart I put some center punch marks 1/2 btdc for both cylinders centered in the oil vent line hole. Then set up the mag with magneto induction timer.Makes timing and check mag a lot easier.

well I made up a pressure test fitting and gave it a try found a few very small bubbles, don't think this is it cause front cylinder runs fine , open to other ideas thanks chris

No leak is an acceptable leak, Chris!

If you saw any bubbles at all, fix that first (or fix a lot more later).

Please use a constant, regulated air supply,

Then you can go on to other things..
