hi its the fuel pump... on the side small little thing.. firstly take it off and clean the small wire screen in it. Then try again..... It works a at high speed becasue the engine provides high enough vacuum to work it,. but becasue of blackage or its failing at low speed its harder for the gas to get through..
I replaced one on a Johnson.. tok 10 mins max motor runs like a dream...
good luck

checked the points/condensers? checked the fuel pump? might be the low speed side of the carb. is still a little clogged.
