Pull the spark plugs and make sure the gaps have not closed up due to it not being checked before install or dropped on floor and not rechecked....
Make sure the firing order is correct...so many times I have found firing order crossed up...1,8,4,3,6,5,7,2....
Remove the carb and make sure NEW gaskets are in place between carb and manifold....then double check manifold gaskets to the head surfaces are NEW !
Replace the fuel filter with a NEW one...
Did the shop install a pilot bearing in the end of the crankshaft?
Did they clean out the radiator?
Did they install a thermostat?
Did they install new heater hoses with new clamps?
Did they install new water pump?
The install fee was cheap for a reason...
I wont look at an Engine R&R on any vehicle for less than $1000 plus materials....
Good luck....
