question of the day

hi Dan or anybody else

i have a question for you on the spring for the pump in my carb..i have been doing lots of research on this to find out all the info i can so i dont have to ask to many questions.. I was going to buy a new pump return spring and then i found this thread

and it looks like you said that only the round stem pumps needed the spring and not the flat( which is what i have) but the pic out of the manual shows a spring on the flat stem pump.. i know that could be just for illustration but Im more lost now than i was to begin with if that is possible lol

and also i see in the pics on the walker site there looks to be a little black cap looking thing that goes on the end of the needle and seat assembly and the needle sticks out through it and mine is missing that as well..

thanks
