Agreed. More testing planned for this weekend. I’ve got a afr gauge installed to help watch the mixture, I’ll be recording that to see if perhaps I’m leaning out somewhere. I also feel as if my converter is giving up more hp than needed.
When I get a chance, I’ll post a time slip for forensic evaluation.
I’ll be testing timing changes and posting that info also. The run I made was at 38 degrees total to start, but I’ll be working my way down during testing to see how right or wrong I was. I started there, thinking the engine might like more timing with the big duration and less than optimal compression.
