Helping a friend with an early-80s Honda BF75... it won't idle, and looks like there's a problem somewhere in the fuel system.
All the lines have been replaced with transparent line so we can see what's going on.
Replaced fuel pump today after leaving it for a few months... we think maybe we didn't run it dry last time we looked at it so part of the problem may be that the carb had guck in it. But generally it's only running at nearly full throttle and just dies if we try to put it down to an idle. It looks like the fuel pump isn't working, as there's barely anything getting to the filter - but there must be enough because at full throttle it runs no problem.
We're going to pull the carb off and give it a good clean but we did that earlier and it didn't help. I'm not optimistic that even with a new fuel pump it'll work right.
Any ideas of other things to look at?
