Yes, but the trigger points only control the timing, not the amount. 
Once the engine is warmed up, even a large change in the timing won't 
make a noticable difference in the operation, since all the gas 
injected will eventually make it into the combustion chamber. 
Consider the fact that 2 of the 4 injection pulses occur behind 
CLOSED intake valves, so the gas doesn't get in until the next time 
they open.

And if there's dirt on one trigger point contact, so that it can't 
actually make contact, nothing works and the engine dies. The FI 
circuitry requires both contacts to work in order to continue 
injecting.

Another thing to try would be the other CHTS. This one may be 
intermittent.  

I'll try to get 2 more B brains fixed and back to you soon.
