check the header boltscheck the starter cable- checker the output shaft of the transmission...
look into tightening the alternator/water pump belt...- put more gas in The Merc!

I removed the carb to replace the main jets. Seems easier although very time consuming.
1850-6 carb info
nozzle size:
0.031"
main jets:
68
noticed that the primary idle transfer slot is not showing at all and that the secondary butterflies are open just a bit. Looks like I will need to configure the secondaries and primaries to defaults and begin the tuning process again.
