Thank you for the useful information. This is my first renovation of such an engine

today came the wars. They are sanded, we can spray the top coat.

Very nice work you are doing. Your progress is quite an accomplishment and this will be a good looking example when you are finished.

hi Karol another a very nice job, i did not realises it's been 3 months since your last post , time fly's or is it old age keep up the very good work

I waited a long time for the rollers to grind. They had frequent breaks for Covid

we continue by fitting all pistons and cylinders. I used a thin seal because of the height of the piston at the top dead center. I want to maintain the compression ratio

I reinforced the connecting rod bushings to a metric diameter of 16H7 to fit my pistons. In our country, the metric reamer is more available and at the same time I have eliminated errors caused during the time of inappropriate storage in the hole for a new, thin-walled stud. the piston rings have a clearance of 0.15 mm according to the document, the clearance at the rings should have been 0.13 mm but that seems small to me. I'm afraid that 0.15 mm may not be enough

The weight of my pistons and fuses is 0,162 kg these are abraded original pistons without a pin.

when fitting the cylinder, I helped myself a bit with plastic tapes. They are commonly available. that is why I was able to do the work myself, without the help of other hands

So I started disassembling the engine head for renovation I'm doing it for the first time, so forgive me for any mistakes
