What is the diameter in mm of the cylinder (PN A130000420) used on the Echo HC-150? I hate to tear it down just so I can determine size tool I need. I know that the cylinder and piston are both damage.

Nominal Bore 32.2mm Ring A101000000, compressed down, measures out to 31.89mm (no end gap) so piston would be right around that diameter, if that helps. Don't have a jug to measure - we'd normally shortblock the engine Although Short Block SB1067 is now OBS/NLA , it used to retail at $99

Thanks that means I needed the 35 mm tool along the 45 mm I need for another project. Now just to see if the customer wants to spend 150-175 to rebuild it. A replacement costs nearly 300.00 but that will be his decision.

you mean the ring compressor tool? Usually don't even need them for most Echo units as the jugs have a taper - you can compress rings with fingers.. only tool we use is a piston support block (sorta like a tuning fork, but plastic) to hold piston square while installing the jug.

Nope. It something else I experimenting with here that I read about. Got to find if it works before I open my big fat mouth and insert a dirty foot. This customer machine is just about right for the trial even through I going try it on one of my Poulan chainsaws first.

As far as installing the cylinders I don't usually have problems with rings going once I get them aligned. I can always use a zip tie for that and make sure I at TDC on the crank.

I just trying something that I have been told is not possible by members here. And with all the conflicting info out there I got to prove it to myself which is true. Personally I think it is possible with the right tools. I got several junkers that are beyond their life due part nonavailability that could restored to useful life again if it works.

I will keep it under wraps for now as I don't want someone else trying it here as if I am wrong it as will be a waste of time, money, not mentioning possible causing even damage.

I will keep a log on what I am doing so I don't repeat failed tried methods. It getting busy here now so it will take me a little longer to do experiments. I spent most of this off season doing some self training on small engine rebuilds. The methods are a little different than for the larger engines that I have done in the past but the concepts are the same. The smallest engine I rebuilt before this year was a 1.8 liter 4 cylinder and largest was a 440 cu in high performance interceptor engine.
