What's on your bench today?

[spudulike]

Yes, then smoothed them, I've ran the saw a fair bit, it's just I dogged right in yesterday and covered the muffler for a few seconds too long, rather than pulling back and moving

Keep us informed, sounds an interesting one!

Well my porting wasn't at fault, but it's killed the cylinder!

Circlip jumped out its slot!

OEM circlip or after market ?

[wisecobandit]

Any pic of the top of the piston?

That's some pretty serious grooves caused and looks more like somethings got in the cylinder. Circlips where still in location etc I take it as that first pic shows grooves around the side of the piston around the circlip area.

[Eddy_t]

No, one had come out, the side the piston had gouged, it had sheared in half, one piece was in the intake port, the other was in the crank base. And I think they were aftermarket, I know I had a right game getting the OEM piston off when I gained the saw as a seized wreck

Classic circlip damage, doesn't look nice!

Tell me about it!!

Wasn't easy getting them apart either, had to whack seven sorts out of the saw to free it! Best get the 254 ported and rebuilt!

Hope you can sort it Eddie.

 

I have a question:

 

Recently got an 056 Super. Running it on a 36" bar. It's fairly slow in the cut and bogs down easily. I've yet to take it apart but new piston and possibly cylinder are things I was expecting.

 

However, it has a warm start problem. From cold, no issue, but if I stop it, then try to start it again, not happening. I've tried taking the plug out, pulling it over and trying again: nada. Almost like turning it off floods the saw. Any theories?

 

It's running a tad lean so is due a carb fiddle and new plug tomorrow am, if I can find the carb on this old bugger!

Very possibly lack of compression. When cold you have enough to start it but when warm, it drops to a low enough compression to stop it starting - had machines like that before. Do a compression check when warm and make sure it is 140+.

 

Other than that, it may be carb settings but less likely.
