About 35:1
try 32:1
A CRF 50 is a four stroke, no premix on this bike.
25-1 running in period for first 3 tanks 50-1 after that
i use a 5 gallon jug and do a ratio of 40 to 1 its a little rich but will run good
no
The fuel/oil ratio is 50:1.
The correct ratio for that particular snowblower engine is 50 parts fuel to 1 part two-stroke engine oil.
You need to run one gallon of gas with 4 ounces of two stroke oil.That is a ratio of 32:1.
There is no fuel/oil ratio, the 03 KTM 450 EXC is a four stroke. See link below.
There are a few things that could cause a pocket bike to stall. Is it a 2 stroke or a 4 stroke engine? But in either case, it could is probably either the carburetor, bad fuel, bad premix[ For 2 strokes], bad clutch/transmission, clogged fuel line/fuel filter, Air intake problems, Bad fuel mixture and so on. The first thing I would check out be the carburetor. This is the most common cause of stalling. Try and clean it and play with the fuel to air ratio mixture screws. If this doesn't help, try checking the spark plug. If it is fouled and needs replacing, then it could cause stalling. If that's not it, check your clutch and brakes. There are a lot of possible causes, just get a small engines maintenance guide and follow the instructions. This should help out a lot.
