Seed truck??

Actually the more I've been running it the more it's been quieting down. As a matter of fact it was really quiet after warming up today. Kind of encouraged me to finally hit it with the timing gun. Actually had to retard it about 16° ?? And it came alive? Took it for another spin and it really came alive. It hasn't been starting cold on it's own, without a splash of gas in the carb. I also gave the carb a good blast of carb cleaner inside and out. I'm curious to see what it does tomorrow cold...

Cold starts with a carburetor here has always been two pumps and hit the key.
