Things to check:

Make sure the centrifugal advance mechanism is working.

Measure the system voltage with the engine running at 2000 rpm or 
higher. It should be above 14 V at the battery. (or 1/2 V higher at 
the generator, or 1/2 V lower at the fuse box.) If it's below 13.5 V, 
replace the voltage regulator. If it's VERY low, as in never budges 
above 12.5 V, you may want to email me for my charging system faq so 
you can check out the whole system to find the root problem.  

Make sure the timing is set to TDC at idle (leftmost timing mark on 
your pulley.)

Make sure the vacuum hose to the pressure sensor is connected on BOTH 
ends.

It's probably not fuel related, unless they (mis)adjusted the fuel 
pressure. It should be 30 psi. There's some chance that something had 
been misadjusted to cover up a problem before you took it in.
