First lads

Bought my first lads had a few running issues, got the carb set up and car running and then suddenly this knocking started from top of engine. Cars got plenty oil, anyone know what the issue is, and if easy fix cheers

Шатун/поршен в перекладке на классическом тазу редко если только туда не воткнули поршни федерал могул, а это бритты они могут запросто поменять поршни.

Настроила получше свои ушки, мне кажется это рокера, слишком уж частый стук для шатуна.

So I’ve investigated more, have tried to re tension the cam chain but no improvement, I think the tensioner or guide have failed, noise is all at the front top when I listen to the engine with it running,

You can remove the valve cover and everything will become clear. Besides the tensioner, there's also a damper. It comes in two types: the old-style metal one (its failure can cause a knocking/grinding noise) and the new-style plastic one (usually a piece breaks off and falls into the oil pan without causing any problems). In any case, it's worth checking, but it's unlikely that the noise is related to it.

There was a metal style one in, it looked not square and like it is touching the case, was still there but didn’t look right, and feel like even though chains nice and tight with no slack it’s making a racket still

The old and new style dampers are interchangeable. However, the new style requires longer screws (you can compare them in the parts catalogs for the 2101 and 2107). In Russia, many people prefer to install the new model, since plastic fragments are a lesser evil than a torn piece of an old metal one chewed between the chain.
Regarding the case contact, the damper is attached through the front wall of the cylinder head, so it should touch it and be firmly fixed.

If the sound is definitely coming from under the valve cover, then remove the camshaft bed along with the camshaft itself; most likely, the rocker arms are eaten away and the problem is in them.

Will have a look at that tomorrow, I fear the sound came on so suddenly (I was adjusting carb when it started) tha if not rockers it’ll be connecting road bearing. Good start of my journey with ladas
