128ld Husqvarna runs bad misses backfires stalls, but if you run a ignition checker inline to plug it seems to run fine. Adding more resistance to plug?
Sounds like you have a poor connection from the terminal lead to the plug. When the lead is plugged onto the plug it isn't connecting right and when you put the tester in line then it connects correctly at both ends

Probably needs a carb kit, check main jet and main fuel inlet jet, is the spark crisp, fat and powerful, try running it with a borrowed coil as this may have an intermittent fault. Is fuel cap breather working or blocked, these small carbs are very sensitive. Make sure all is well with gaskets and diagrahms. Good luck the Yeti

Most chainsaws and small engines are 1.5 turns out.
You need to set the mixtures for the carburetor. You will find a Low and High adjustment screw. At idle turn the screw in or clockwise until the rps starts to decrease. Then start turning it out till you hit max idle rpms. Turn screw back in a quarter to half turn and it should be idling smoothly. Be careful here and get someone to hold saw if necessary but hold in throttle to full speed and do the same with high adjustment screw. turn it in till rpm starts to drop then back it out until you get to max rpm and it won't go any higher then turn it back in a half a turn.

Dirty air filter, dirty fuel system, ie carb, lines, fuel tank. Poor air fuel mixture srew adjustments.

Check the gas line. The Husqvarna is having a problem gas additives causing the gas line to deteriorate and colapse.
