I've got a 75'Scout w/345 Auto thats been sitting for about 8 years. I got it to start and run by a new battery and starter and pouring some gas in the tank. I also poured some fuel into the Carb. I repeat the Carb. "priming" intil it warms up and runs on its own. I tried to run it the other day by Priming the Carb. as usual. No luck. No spark,no rumble, nothing.The engine has juice and the starter rolled over but nothing as far as a "pop" or "spark" . Is my Carb. the problem. Is it worn out and trashed up from sitting so long? Help..
