Would you believe it ??
Trying to set tappets on my little landy Kohlar engine only to find that they are hydraulic lifters 🤔
I'll have to flush the engine and put fresh oil in to see if that solves the noisey tappet problem, it's been stood quite a while so maybe it'll get better with running.

Took the carb off, had no carb cleaner but did perform the aforementioned butchery to enable me to alter the tickover:

Backed off the throttle and ....... no....... it still wouldn't idle.
So turned the idle screw up.
No better AND it had flooded so I had to "de-flood" it before it would start again.
Again ran like mad on full throttle, but again..... no tickover.
So wound the tickoever jet a bit to the right to lean it.....
Still wouldn't restart until I de-flooded it.

And still no tickover.:mad::mad::mad::mad::mad:

So not a happy chappy.

Took the exhaust off to look at the spark arrester. Which is basically just a load or wire wool inside it.

I had the opposite on a 2stroke. Idled but stalled when you tried to rev...

First thing I did was pul the carb... Took it apart, cleaned it all nice, checked gaskets were seated nicely, cleaned needle etc etc... problem remained.

So I looked at everything else, cleaned the fuel tank, and replaced with nice E5 petrol mixed properly. Took the fuel filters, air filters and exhaust off and ran it like that and problem remained...

At this point it was pretty much stripped down to a fuel tank, carburettor and cylinder head, and of those 3 the thing most likely to go wrong is the carb.... Got a new one and it's run perfect ever since - musta got clogged somewhere I couldn't get to with cleaning

So might be the carb giving grief even if you have cleaned?
 
I bought a brand new ((old stock) briggs and stratton engine cheap
It ran perfect, I parked it for the winter and come spring it would rev but wouldn't tick over
Tried everything, eventually bough cheap carb off internet and it's run perfect ever since

Old fuel can sit in a carb over winter and turn to varnish like gunge, if it doesn't block a gallery it may restrict it enough to be a pain, carb cleaner needs to be soaked for a while I reckon and then followed with a blast of air ...
 
Ran it out of fuel on last switch off so carb was empty and it was stripped and cleaned 🤔
I leave the fuel in my lawn mower over winter and it starts no problem every spring
Don't know what the problems are, maybe insects crawling in for the winter because it was stored outside

Who knows, they have their own rules, I'm sure ...
 
I've had some success with two stroke carburettors by immersing them overnight in a strong solvent like acetone or thinners. If they're a diaphragm type I take the diaphragm out, in case the solvent damages it. This helps dissolve the congealed two stroke oil in the tiny holes.

I was told once by a mechanic in a shop that sold strimmers and chainsaws to reduce the amount of oil in the petrol. I'm reluctant to go too low, however, because that's the only source of lubrication. This man's business relied on people buying new ones, so I don't suppose he minded them wearing out quickly. I'd rather risk a drop more oil and keep the engine intact for longer.
