How to refuel a sym jolie 50cc scooter, do you mix oil into the petrol tank, or do you fill the oil and fuel seperatley or does it mix it itself????

Pretty much all are normal petrol in the fuel tank and the oil is on another tank. The oil is mixed as it enters the inlet manifold.

Your manual is here. Section 2-3

You might get lucky with new spark plug(s) and I assume you mean 2-stroke oil. Otherwise, drain tank and replace any fuel filter in system, then re-try with fresh gas and new plug (s)

I have had 2 strokes for nearly 20 years. got my first 4 banger yesturday, YZ250f 2004. wot should i be looking for, where and when do i fill up the oil, and it is just straight fuel in the tank is,nt it....

Checking the engine oil couldn't be any easier. On the lower left side of the engine, by the shift lever, is a round sight glass. With the bike held straight up, off the side stand, the oil should be somewhere near the center of the glass. Above the sight glass, also on the left side of the engine, is where you pour oil into the engine. On the bottom of the engine is a drain plug. I change my oil about every three months - or more depending on how much I ride. Use any high quality 10W-40 or 20W-50 (depending on the climate where you live) motor oil.
And yes; use straight (premium) fuel in the tank. The other thing that you will need to have done, perhaps every 50~100 hours of riding is a valve adjustment. For that I suggest you either buy a shop manual or take it to the dealer. Otherwise, there's not much else to do that is all that different from your previous bikes; oil and adjust the chain, tighten the spokes, clean the air filter, ride, etc.

Wrong gas in the tank

I certainly would not suggest putting break cleaner in any fuel system...
I take it that since the engine is not seized that there was too much oil in the mixture.
you can rinse your fuel system with a small amount of straight gasoline...take out the spark plug and pull it a few times to allow the gas to get into your carb then dump the gas out and pull it a few more can take a little straight gas and pour it into the plug hole to remove any oil build up in your cylinder...then pour it back out...then
Buy and install a new spark plug...mix a small amount of gas/oil at the proper mixture and give it a go...if you dont have serious engine damage, you should be ok..
if it still doesnt start, repeat the procedure

good luck

Scooter losing power in moving forward when stopped at stoplight. Also, loses power en route. Reached 350 miles on odometer. Went to change engine/gear oil. Took off ''oil pan'' screw. Only ~<50 mL came...

Check your jets in your carbs and also could be bad fuel. Poor some sea foam in it and some new fuel and check to see if the inline filter is plugged and check your air filter as well.

Sparks and burning from exhaust, no control over speed.

You have a unique problem caused by excessive oil and carbon build up. The sparks are from excessive oil burning, as is the smoke, and not being able to shut the engine down or contol it is called pre-ignition. There is so much carbon built up inside the combustion chamber it is acting like a glow plug when it gets red hot.

Beyond that I can't say how or why you are getting the excessive carbon build up, other than from the oil.

Double check the oil level. Maybe somehow the engine is being over filled?
