Is this repairable or replace? pp295

Cylinder

Mike Its coming along, slowly. Need to find a better dremel type unit. So was trying it by hand. Not much room to remove material. Will post a pic later on my progress.

Once I get my new dremel, can I just bevel the underside of the intake port until the chipped surface is uniform?(those sharp edges, right?)
Can I remove too much material and really screw things up.??. Looks like I may need to bevel out 1mm or so. Or is the underside of the port less important to a good running engine? I'm probably going to do it anyways, (those sharp edges), but curious.

Any porting guys listening.

Pauly i went and added the cylinder and crankcase assembly and the piston and ring assembly and the flywheel parts on my site since they were not on there either just thought i let you know

$ 26.63 for the piston and ring i was being nosy and see ereplacement is wanting over 34 for it

here are the part #s for your reference

if you choose to being needing any

530071490 - 530014943 Cylinder crankcase assy chrome plated

Have you figured out what you're going to do about the coil mount bost being broken yet? Not trying to discourage you. Just that IMO the coil issue is a much bigger one than the porting. If you come up with a good solution to the coil thing, I will go over to the saw boneyard and find a flywheel for you. That guy owes me a favor anyway. No, they do not have any 2900/295 jugs (I already checked.)

You mean he has a coil mount part broken ?

See beginning of thread. Do you have any Poulan 380 Super top ends around?

Saw Dr thank you for the offer, will check out flywheel VERY closely when I get these things sorted out. Please save your favor (I think you might not want me to have it blow apart and hurt me? me too!), Not discouraged and really appreciate the input from all the guys at this site
Still debating on just throwing a new cylinder on it and solve both my chipped liner and coil mount issue at the same time. (can return my JB weld and that would cover $10 Canadian towards the better solution

)

But Would this cleaned up piston be worth reusing in a NEW jug? Still trying to keep the costs down. TRY it and see or could it damage the new jug? Or would it be fine and just not run to its potential (ya can of worms, some think this is a poor saw anyways, but it would be more than I need when running) Thanks to all the posters that get that idea, loved the the comments!

Got my Dremel and will see what I can Salvage. Here is a better picture of the chipped area

and what I have cleaned up so far...

I am planning on trying the JB weld route with a little bracket if it cleans up better. If not I will be talking to you Calvin, thank you for putting those p/ns on your site: decisions, decisions (maybe delusions) AT minimum need bearings and the jb weld; or bearings, cylinder and maybe piston kit (oh and maybe the oil worm)

IF the bearing(s) were good it would be a no brainer for me to just continue at best effort and just throw it back together and :glue the post and run it, but that's not the case now...back to the grinder for me, literally.
Thanks guys
ps Still need to get the oil worm gear off too without having to buy that tool that Modifiedmark posted. can it be done? home made puller?
