Poulan 2300CVA Saw

I tore this saw down and discovered the usual wood chip in between the reed valve under the carb.
Completely rebuild the carb with a new kit, and install new air filter and fuel line.
Put it back together and the compression test showed around 80PSI.

Decided to take back apart and reseal the crankcase halves and installed all new gaskets. Closer inspection found that the piston and cylinder walls were scored a bit so I honed them the best I could. Next I put a new piston ring on.

Compression looks to be about 90 PSI and it'll need tuned yet with the bar and chain on it doing some cutting.

We have life after many tear downs. :)

how many inch is the bar

[Ajaces]

@MrFrj123 If I recall correctly, about 14".

I believe the CVA is printed right ofter 2300, on the side cover decal where you tighten up the bar and chain.

Hey there. I just started rebuilding my it175 and was wondering if it is normal to have your compresion escape from the rings slowly if the cylinder and rings and piston are new and dry.

[Ajaces]

I'm not 100% sure, you shouldn't loose much though. The oil will definitely help seal it.

@Ajaces well some 1 told me 16 u might be right

@rasr10 Yes it is normal to have it slowly leak but you shouldnt lose much only about 8 psi every 35 seconds is normal for me

this is better then porn

@rasr10 if you appear to have little compression, add some oil to the cylinder and crak it (not start it) and if compression really increases, you need to replace the rings. if it is a new engine, don't wory about it, it just needs to be run-in

@coshyno You don't hone a chrome-plated cylinder. The plating is thin, and if perforated at all, the jug is junk. Not to mention that the plating is hard. Mfgs seem unanimously to recommend tossing junk jug.

The purpose of honing a cylinder is to provide micro-pockets to retain oil, for lubing rings. AFAIK, rings meant for plated bores have different metallurgy than rings for cast-iron bores. If you toss a jug, you may need to replace piston too, and certainly the ring(s).

I've a 2400- rear grip version. Found that it runs fine, with negligible smoke with 50:1 synthetic mix. Somehow Poulan 2.3 cid engines seem to be very noisy and powerful.

The 2400 has an easily bent cv spring and excessive chain oiling. Pvc fuel line crumbled, replacement Tygon should last in contact with fuel.

But not a bad saw for a buck in '95.

@coshyno You can use a peice of 100-150 grit sand paper & do a once or twice turn in the cylinder to get enough cross hatch to "seal" the rings...

Nice engine. I have a similar saw, very tough to start and idles poorly. Will need a tear down like yours. The previous owner oiled the sponge filter with bar/chain lube...I was baffled.
