Ty250 c Carburetion query

Featured Replies

Greetings, just bought a 76 ty250 fitted with a toko flat slide carb, it wont idle properly races then drops right off, is using twice as much fuel as my previous ty 250 with a standard carb, does have plenty of top end, AND does pull well from down low. has got the fly wheel weights. Plug is very black, running it on 50 /1 motul mix with 98 octane unleaded.

is there any one who would know the needle and jet sizing for these carbs / bikes ? Clubman A rider .

Any thoughts on this ? Thank you in anticipation.

Believe it or not but you can get Chinese copies of a Chinese copy oko .if you got one of the cheapest ones it will never run right .i got one and it had no pilot circuit cast in it 

maybe post suitable photos so people can tell which carby you have there and is it really called a TOKO or is it an OKO and is it really a flat slide or is it a crescent slide? There are lots of different carbies out there
