Why can't I drill it out??

[JNJchev77]

I removed the TB blade last night and looked on the back part of the blade. The two holes that are usually present were blocked off? Not sure why...? I couldn't tell initially when I got the TB because the blade had been smoothed off as well.

So I drilled them out. (after researching that most 4.8,5.3,6.0 TB blades have two holes). fired it up this morning, and it still was doing the same thing. However, I tried it one last time and just tapped the accelerator and it stayed at idle... Sounds like it could be the tune as Moose and Smoky kindly stated

I left the battery connected and will try it when I get to the crib and see if she fires up without any assistance...

Far too many people use regular bits and drill it out to "What looks good", but this can create its own set of idle issues. It can be done but its the kind of thing that should happen 1/64 at a time with machine bits, not really a powerdrill kinda job.

That being said, if yours were blocked, re-opening them isn't a problem, provided you can do so without boring the hole over.

I gotcha. I contemplated buying a new blade, but since the holes were there and I had a bit that "looked close" lol, I gave it a shot. Didn't have to bore out the holes at all.
