1973 honda st 70 starting problem

Hi people

i have just bought a 1973 st 70 and having problem starting fuel is getting to carb but not into the barrell, i cleaned the two jets in the carb where you remove the float and no joy but if i poue fuel into barrell it fires? any advice??? also i swilled out petrol tank due to rusty inside tank?

help please???

First, fit a small fuel filter in the hose between the tank and carb.
Second, check if the carb gets filled by fuel and that the floater is working properly.
Also check the colour of the spark plug.
Re-check the jets and fit all new gaskets. Do an air leak test afterwards.

Good luck!

Try to free it with a small copper wire, or 1 single wire from a brake/throttle cable.
