Don’t need no stinking safety
Yeah they just like dem breaks, PPE and that fancy hearing protection gunk- they all for sissys.

Mr. President - I will get into the carburetor on Monday, I will know more about what is needed at that time.

Some new prototype gasket kits for for the full 50/51/55 top end although a little revising of the shape on the carb gasket is needed, also a full kit for the intake block on the 254xp/257, and of course the kit I already had for the older style intake of the 262/266xp, working on the 272 amd smaller similar shaped 61 intake block gaskets!
I'm no maven but have a neighborhood rep you know?
Bud handed me his 025 "back up saw" chain dull, it had been cutting sawdust, then put away wet. Won't start he sez.
"some compression" cleaned filter, it fired off a bit of gas poured in carb. Checked fuel line, filter, dump gas refill. Cleaned plug. Will now run "well" on the main throttle response etc good, but won't run at low speed, won't idle. Let it slow down, it kills, Choke to get'r running again, repeat. Loosened carb, pulled the idle mix screw, sprayed in carb cleaner.
piston walls look OK from exhaust port. rings are free. Only getting 80PSI (throttle open) Not excited about removing the carb completely, spending 4 hours etc. any other "quick fixes" or other likely "problem is" guys? My inclination is to hand it back and say "above my pay grade".

Increase the compression to 100psi and it will work better
Maybe if I pull the rope harder/faster?Increase the compression to 100psi and it will work better
If you trust that compression number is accurate, it's just too low. Time to tear down and inspect piston and cylinder for wear or broken parts.

If it slows down and stops, check the engine for leaks / The question is whether you can cope with it all. This looks like a full rebuild
Only with the throttle at partial settings it"ll keep going at high throttle. Still need to go out and see if it runs well under load....
Thanks for the help, hints, advice!

Since it wouldn't start, run at all, and after some jiggering it now is working on the main, wondering if I can get in and find a plugged circuit that feeds the idle needle? Don't know much about these (two stroke) carbs.
The real question is; why would I want to take this project on???

I used my first chainsaw for about 10 years, although it was leaky and stalled at idle after about 5 seconds, but it certainly had higher Compressor / Partner 465
Because you have already taken it on mentally to the point where it bugged you enough to post about it. And you touched it last so anything bad after this is your fault.The real question is; why would I want to take this project on???

Not on the bench yet but I have a third 49 in a box that is a great project. I DO NOT need another 49 at my age but winters are long in upstate NY. Could be the next project if I can find a few parts at a ok price.
Just went rounds with a pop rivet stem stuck in my rear tire and leaking..... grrrrrrrr.
Air compressor and tire machine don't like 37* weather.

I'll console you that it's 7F here / Such a little Alaska
in Europe, We haven't had a winter like this for over 10 years
I have one just like that one, only mine's filthy, waiting for Spring to get here for a good cleaning..
This 025 is buttoned up and for sale "as is"
