If you have replaced the carb and properly installed new coil with proper coil gap it may not be able to exhaust properly if the exhaust port is stopped up. It is a common issue with Stihl machines. How do the fuel lines and fuel filter look? it sounds like it is a fuel issue, and new lines and filter are the only thing remaining if it is exhausting properly
You shouldn't have to pull exhaust off to remove spark arrestor.
Look at where the exhaust port exits machine. Should be able to put a 5/8" socket on it and remove it
Here is a manual on the machine
See page 39 #5.
Ah, didn't know that info sorry. Yes, you will nee to pull plastics off then. Sorry for not asking, as I am in Tennessee and we do not have the same emissions
Can be, but not very common. You have all new fuel system pretty much, so.... nothing else really to check. New lines, New filter, new carb, gasket is good? Nothing else is fuel related.
