Good lord, so when I loosened the 4 bolts on the outside bottom of the outside plastic case, not only did it loosen the clinder, but it also loosened/cracked loose the bottom half of the engine case from the main engine block, as well as entire engine mount to the bottom plastic shell? Why the...

Well the 4 bolts on bottom of the outside bottom shell released the clinder as well as the bottom of engine from the plastic shell case. Not sure what you mean about the seals. I didnt crack any engine cases apart, just pulled the cyinder up off of the main rest of the engine case/ block which...

I’ve worked on small mopeds and dirt bike engines before, you unbolt the cylinder, pull it off, attach new piston and rings and bolt cylinder/head back down. Job done!

Well what the “F”, I need to take better look at this brain-child of a desighn under daylight. I think I might be beginning to learn now why people just throw these saws away! ********

Sounds like a very poor design, seals that just fall out, but yet needs to be tight as a drum, how the H did it ever run before? Maybe this seal is from the clamshell case? Why would I need to seal anything more than the clyinder back down to the block with new RTV? The plastic shell is just a...

Oh good god, what have I unleashed? Yes it seemed to simple to be true to disassemble. Yes I believe the whole dang engine is loose after taking the 4 cylinder bolts out. What the heck do I do now aside from getting the wrist pin out. I bought some ultra copper high temp rtv.

And yes, thanks to all who followed my thread and helped. Piston was inspected like you told me and the scoring was noticed. So here I am now

Is the clip burried in a carbon deposit on the other end? See photo

I might have to get out the exploded view of saw to id this seal?

Im thinking the seal was from the case or outer shell. Not sure, it just fell off when I turned the saw over to try to shake out the clip from the engine case after the one clip broke apart.

Yes sir this is me, I ordered the top end kit, very happy. Just trying to figure out how to grab the clip?

Why do I need to disassemble more, I took the top cover off and muffler and carb, then unbolted the head from bottom and slid the head off? I just need to remove pin, insert new pin and piston/rings and bolt down the clyinder again. Am I missing something, if so please explain?

Heres the photo of the pin, do you see a clip? Also what the hell is this rubber gasket for that fell out when I turned the saw over?

Ya, well it would be nice to find a end to pick under, I think my crankcase ate the clip from the one side. Damnit! Now I need to make sure I retrieve this clip somehow?

The clip must be burried on other end of pin, I cant even see the clip end to pick! I guess I need to get a scratch all “ice pick”. I already bent the ends of my great grandfathers starret metal compass, dumb ass me. I had nothing else to try. Very frustrated!

How do I remove the pin that goes through the piston to change piston? I think its called a wrist pin? I have a new piston, cylinder, pin and clips, however the old clip doesnt appear to be the type you can squeeze and pull out. I believe I broke out the one side that has the divot. But cant...

Can you tell me how to identify what Type 2150 I have, 1-7 type and which seals should be replaced if pressure test fails. I’ve included a link to a pdf download exploded parts diagram of this model. I cant tell if there is two crankshaft seals and two bearings (both sides) , or 2 bearing (both...

Geesh! I guess I should have looked closer, didn’t realize that so much disassembly/reassembly is required. I’m more familiar with moped and small motorcycle engines of the past. These used 4 long stud bolts that held the clylinder/head on, and nuts could be removed all the top, and cylinder...

Hello and thanks for your reply. Yes, hopefully I don’t need to take the saw aparts any further than necessary. I mean if this is what it takes I will, but for a saw that has only seen a hour or so usuage each year since purchased new by my father initially , I would hope the seals to still be...

Ok, so where would you suggest as the best place or places to get crank seals, and this Motobond or similar? I thought maybe the cylinder would come with a gasket?
