Nice lookin' muffler mod! Did you use self-tapping screws? Or riv-nuts on the muffler? Cheers!

Here's a scan of the 7900 spike set! Figure someone might want to get some cut out :) Also awaiting a 5100s in the mail! Snagged a 'burned up' one for $120, and a nice piston/cylinder kit for $40. Budget beast of a saw I plan to uncrimp the muffler, and gut the internals, as well as a retune...

I've got a 562xp (2258) on the bench today, that has corrosion in the crankcase unfortunately... It seems to be interfering with the crankshaft balancer (counterweight?) as it moves along the bottom of the case. It still rotates fully, but definitely has some drag when it apexes the bottom, and...

I'm gonna try a $10 china piston, after beveling out the exhaust. Figure it's worth the experimentation. Got some long burr bits on order to reach!

The walls are clean as can be, and the roof dings don't really seem to protrude downward... But the damaged exhaust seems the most concerning. I figure it wouldn't hurt to try opening the exhaust until the plating damage is ground away? Seems like 1/16" above and below would clear it up.

What do y'all think about the recoverability of this cylinder. The dings on the food bother me less than the plating around the exhaust being chipped. It's a 562xp

I was viewing it on my phone, and didn't realize it was for both spikes. So I made the purchase :cool: I'll be scanning them and posting the dimensions onto the Dolmar thread. I'd also like to see a set with a little more meat on the bottom, for a roller chain guard.

I saw that but ouch, $40 for a spike hurts my frugal soul. haha ....it is the last part to make my 6421/7900 complete however.

Personally, I've only seen aftermarket 7300, and 85cc big bores. Haven't come across a '7900' clone yet... The lack of markings 'mahle' or part numbers is certainly suspicious. Maybe ask them to measure the piston diameter? But also, I'm green to dolmar.

Thanks! I do the designs :)

Thanks Jake! The dog on the bottle was Gus. He passed in 2011, but earned immortalization, on the label :)

Got another burned up 400c coming too, now :p. This one was straight gassed, so we'll see how it cleans up! There is an aftermarket piston/cylinder kit available now, but it's a standard aluminum piston... I'd rather shell out the dough for an OEM magnesium replacement. No shortage of saw...

I'm leaning Maxflo right now too, as it's the best bang for buck, seeing as I'm in need of a filter, and filter cover. Unrelated to air filtration - has anyone cleaned up magnesium piston transfer from a 400c cylinder? I imagine since it's softer, that it should be easier to remove than...

Part no 957213040 edit: looks like y'all already solved that!

Although, on the note of a 400/362 or 462 for that matter, it looks like Max Flow is releasing new filters for these saws soon. Noticed this on their site while looking at their 500i kit. https://maxflowfilters.com/mf462%2C-400%2F362-kit
