How often sparkplug change?

[Huskybill]

At the end of every cutting season when mud season hits my saws are done cutting I completely clean the saw, clean the air filter, lube the clutch, clean the bar groove, dress the bar rails, grease the bar nose, sharpen or replace the chain, change the sparkplug, top off the gas tank. Fire her up do one test cut and she goes away for her nap. If I get no break between cutting I stop and do this maintenance anyway.

If the carb is adjusted correctly the sparkplug won’t foul. But once a year I change it anyway.

If once a year is a good recommendation I would like to know also.

Why change it, if running nice. You may be replacing it with a new bad plug.

I have never replaced a plug in any of my saws. If they run correct im not gonna throw parts at it for no reason. Thats just my 2 cents.

My BIL replaced the plug on his 026 he just picked up and the thing would not run worth a crap. He had not run it with old plug so never knew what it was like befor. He pissed with it for quite a quite a while befor putting old plug back in and then it ran mint.

Same here, never change a plug if the saw works, havn`t changed a plug in a saw for many years now.

I don't change plugs ever.

If the saw is acting up, I change the plug. IMO, it a good place to start. Over the years, it has been something else, but it serves as a reminder if not a solution.

If the saw runs right I keep the same plug. If it is not running right I replace the plug first as that will eliminate one potential problem as I have had a plug go bad on a couple times. If the saw is going to be sitting for a while I pour the gas out and let it idle until totally dry.

I have changed a few bad ones. Auto-tunes seem to like good plugs. Tree service had a 372xt he could not get to start. Pulled plug set gap, checked for spark, reinstalled, would not fire. Good compression, getting fuel, pulled plug again, held up and electrode was loose, sliding in insulator.

Not until they need it. I ran my first saw (Husqvarna 50) for 10 years on the same plug. I changed it because I thought it was time. It didn't run a bit better with the new one.

I have a 562xp that started running rough, and when I changed the plug it ran like a new saw. That doesn’t happen often, but it worked with that one!

Never change plugs.

I figure pay now or pay later Murphy’s law can bite us at anytime. The sparkplug is the weakest link.

You carry extra new spark plugs right? I save my old plugs and clean them. They have plastic sealed tubes to keep clean plugs in. Your local dirtbike shop sells them. Or pvc with two end caps works, one glued one loose.

Why save them. Your not going to reuse that weak link are you?

I've got one 06 model saw and another that's near the same age, never had the plugs replaced. The other old saws, who knows cause I haven't replaced them cause they run. I replaced one plug on a blower once but it was 20 years old and would stop sparking under pressure and it was a Champion.

I dint change a plug until it’s needed. I carry a mall organizer kinda case with 2 extra plugs, 2 extra starter ropes, extra screws and bolts, extra bar nuts, small screwdriver, and my tach(because my hearing isn’t the best anymore especially with the higher revving saws)

We were playing with the Allen diagnostic scope at the dealer. We took used plugs and cleaned them, filed the electrode flat again. The machine didn’t know the difference between used or new. this was back in the 70’s.

No i dont carry new plugs. I carry multiple saws.

If i had a suspect plug i would pull a good one from another saw to test so im not playing parts darts.

I can remember the days when spark plugs were sand blasted, electrode filed flat again, and reused. We were thrifty back in those days.
