foundryratjim Posted June 10, 2007 Author Posted June 10, 2007 I didn't realize what i was looking at....... Duh! Adjusted them. Will test ride tomorrow and post if it made a difference.
foundryratjim Posted June 27, 2007 Author Posted June 27, 2007 Backing out the mixture screws did make a difference and elinated almost all of the back firing. I have since installed a Dyna ignition module and all the backfiring has disappeared. The engine seems to be running smother with the new mudule. I had to lower the idle speed though and it seems to be more cold blooded than before. I didn't realize what i was looking at....... Duh! Adjusted them. Will test ride tomorrow and post if it made a difference.
