Hello,
I have a Weber DGV 5A (32/36) carb on my 78 Midget.
I know that it is running too rich (emission, black plugs, smoke, backfiring
...)
I went to a friend's place and he has a cool TRANSPARTEN spark plug that you
can place to replace an plug in your engine and SEE the spark, especially
how yellow/blue it is! Really cool toy!
Ok, so here are the results of the test:
In order to be OK, I had to:
Change the primary jet to 1.30 (from 1.40)
COMPLETLY close the idle mixture (and increate the IDLE speed in order to
avoid the engine stalling)!
This seams to give a much better mixture (emission WAY low, plugs much
better, no smoke, no backfiring)...
However, I am not happy with the Idle setup and I plan to change the idle
primary jet from the standard .55 to .50 or even .45...
Does anyone has a similar setup and can tell me how their carb is tuned up?
Thanks, Cyrille
