Other thing you can use if can get in behind is a Rivnut

Thanks for the suggestion I'll see if have room but have feeling its a little difficult to get behind it to fit one.

So I managed to get the cylinder off and the piston is well and truly scored, but to the untrained eye I think the cylinder is OK. I take it its the shiny areas that would need cleaning off of the transfer and then gentle rotational rub with 2 stroke oil with fine wet n dry and then thorough clean after.

Yup, doesn't look too bad, new piston and the work you mentioned. Just make sure you know what caused the issue and fix it - probably bad mix but without seeing the machine.............

I did find that one of the bolts attaching the carb was stripped and when sprayed in the carb cleaner can see it leaking out between gaskets, so that may also have some bearing. I will of course check the carbs once rebuilt. Also make sure I use the right fuel ? as I dont really have much of a history of the unit.

If that's 52cc have a check around as many use that as a generic set up so could probably get piston and jug cheap enough

[cygnusnsf]

Ah OK thanks unfortunately its a 41cc nevermind. Just trying to find some Harpic Blue now to clean off the transfer.

Seems Harpic blue is little more difficult I guess Harpic Power plus is a possible workaround as contains the hydrocloric acid same as blue anyone tried that?
