Use a timing light to get a ball park setting and then your ears will finish the job.

well you cant damage it by doing that but if you put too much n and didnt shake it well it will settle at the bottom of the fuel tank and fill the carburettor up with oil as oil is heavier than petrol.why are you not using the oil tank and oil pump fitted to the bike ?best thing to do is put a new spark plug in it turn the fuel tap off roci the bike bacwards and firwards to mix the oil and fuel in the tank,and drain the carburettor by undoing the 14mm nut in the centre of the bottom of the carb,then turn the fuel back on and try and start it up.

You would never mix any fuel and oil for the crankcase. If it is a 2-stroke engine, the fuel and 2-stroke oil will need to be mixed before entering the cylinder. Some engines have an automatic mixing setup - those have a separate oil reservoir for 2-stroke oil, but it will usually be a plastic tank, located nowhere near the crankcase. On a "4matic" engine, it fires like a 4 stroke, but there is no crank case, and the fuel needs to be mixed like a 2 stroke. What is the vehicle you are referencing? A dirt bike or street bike? It seems the CR125 and NR125 are both 2 stroke engines, so somehow the fuel needs to be mixed with 2-stroke oil. Can you take a picture of the crankcase oil cap?

pull out the plug clean it off and while out crank it a few times do not give it any throttle action at all and whey you put it back in ,, in a few min close the choke and hit the throttle 1 time and it should start , start opening choke as it warms up

dirt in carb

clean the carb !

crank seal is knackered. You need to remove the rotor using a puller andsee if theseal can be replaced without splittingthe crankcase?
