So. With my new, lower float level (too low really) I have 3 cold starts, all way easier. Not necessarily because of the float level adjustment but the float level adjustment was what prompted me to pull the top off of the carb which is when I discovered my accelerator enrichment pump seal was perforated. With three successful cold starts under my belt I decided to take it for a drive. Everything worked well enough on my trip to town, I pointed it up Cohasset road and drove all the way to the mountain store up there, which was closed. Noteworthy is that my fj55 drove the whole climb in 3rd gear doing 45-50 mph.
Previously, sections of it were 35mph 2nd gear crawls. I'll fine tune the float level back upwards but I think that for now my carb and ignition are working about as good as can be expected. It's running real nice. Makes me wish I had someplace to be!
