That is what I found out about those type plugs in the past.
That is what the book suggested and they were a pain to find here in town.
I'll cross reference the other type and put them in.
I think I had L77JC4 plugs in during the last run, they performed about the same.
Got two carb kits yesterday and the other should be in town Thursday.
Not knowing any real history of the motor rebuilding the carbs will at least give me some piece of mind.
All the coils, wires and one powerpack appear new. The best indication I get out of this motor is it had some problem and they did several things to it to try and improve it.
The thermostat covers have been removed and resealed. One temp sensor had been cut and respliced but not removed, come to find out it was defective. I have all ideas the thermostats are missing. That will be my next venture cause the engine isn't getting much past luke warm.
One more step at a time. :-/
