TFI Distributor Problem
TFI Distributor Problem
My 434 has an aftermarket TFI distributor. It has run good since it was installed.
Recently I had some crossfiring and had to replace the cap and rotor. I also reset the timing with the Spout removed to 10 degrees BTDC. The crossfiring stopped, but now it pings at light throttle. It never did that before. Also, while setting the timing, I noticed the timing mark jumping.
I just removed the cap again, and found that I can wiggle the rotor back and forth. It has more than a few degrees play.
Should an installed TFI distributor have play in the rotor? There are no springs below tha breaker plate like a normal distributor.
