I did not mean to imply that your pump has a problem, I'm sure it was done to perfection, he is clearly a pro with these.
The engine I am dealing with sounds extremely "diesely", smokes and seems to lack power. I'm comparing it to my samurai 1.6 which ran very strong.
It's been a frustrating job, especially for my friend who has been with out this car for a while now. I must have screwed something up with that advance, I'm all out of other idea's. Were gonna take the pump out again tomorrow and look into the advance, something's not right since the lever does nothing to effect how it runs.
I am confident it is timed right (staticly), but maybe when running timing changes some how, I don;t know, it definitely sounds like a timing problem though.
