tricky problem 70hp johnson 1990

hi guys
i have a 1979 70hp johnson.
it gets to mid throttle then stalls immediatly
i have checked fuel line and sprayed some carby cleaner in but it hasnt seemed to fix problem
it will stall mid throttle in forward
also by hand at engine when engine is in neutral

when i lift the lever on the controls however it will go to full throttle in neutral then will go all the way in forward

But if i drop it back to neutral then reverse, go forward again the problem comes back, unless i take it to neutral and lift the starting handle up again.
anyone have any ideas?
 
Re: tricky problem 70hp johnson

If you have proper compression and spark on all cylinders, your explanation indicates fouled carburetors. If so, remove, clean, and rebuild them.
