Meteor cylinder defect

[Screaming Stihl]

Replaced a Stihl ms362 cylinder and piston with a Meteor kit. Attempted to do a pressure test which showed I had a good leak somewhere, checked the crank seals but they were good. Couldn’t find the leak but remember reading a comment about putting the saw in a bucket of water. Voila! Bubbles coming right out of the side of a new cylinder! You can see the hole directly above the “e”. Hopefully it will help someone else.

Looks to be a casting flaw that made it past quality control- so a good candidate to ask for a replacement to be sent.

After you graciously accept your replacement, if they don't require you to send it back you can probably drill & plug that hole fairly easily too

Had a 372 oem xtorq cyilinder with a leak above the boot mount, casting flaw by the looks of it- was a used cylinder but ws that way for a while.

The disappointing part is that the cylinder was ported and band cut for squish. Not sure if they will say it’s “modified”.
What’s the consensus on using JB weld on that? That goes through to the transfer port? Drill and tap for a plug, weld it or JB? I figure I’ll hear back from Meteor this week.

Yeah, na, that changes things up- I would suggest if it has been ground on- you own it.

It seems like it'd be hard to get enough JB weld into the pores to be effective, unless they're larger inside the transfer port. There might be a less viscous epoxy that you could use.

You could grind it and have it welded back up but that might cost more than the cylinder did.

Yep I think so too. Where hole comes out in the transfer port I'd say any of those fixes would work. Welding would be best if not overdone. JB would be fine as well just have get the area inside and out as clean as possible. Drill and tap wold work OK too........just more parts to keep tight.

If it doesn’t interfere with the case, run a burr overtop of the outside of the transfer and lay a small puddle of JB on there. It will last forever.
