My Honda 24 hp GXV670 manual tells me to use a "wire-type" gauge. All I have is a disk one.

Will it hurt my plug if I use the disk to measure and adjust the gap?

Will it give me an inaccurate measurement?


Thanks

Ive always used the disc type gapper, and never had any problems? As long as you get the proper gap on the plug, I dont think it matters which tool you use.

No, the plug isn't made by Honda anyway but I do hope that if you pulled the
old one that you're installing a new one.

As long as the gap is at the specified measurment then it doesn't matter how you did it. I use this tool....

Thank you for your replies. But does this look right to you?

The first pic is just how I took it out, about .45

Second pic is at the adjusted 'correct' .75. I'm no expert but it seems mighty bent out of shape to me... does it look familiar to you?174264

BTW, these are the old plugs. I have brand new plugs right here.

i think you want .045, .45 is almost half an inch

Oooff! It's been a long day! Note the dangers of operating on too little sleep.

Thanks for your help fellas, I always leave here better-off than I arrived.

There is no way your equipment wouldve started up with a gap like that!! But I can understand about trying to function on little sleep, its almost impossible to do.
