Heavier throttle (mostly) issues
MP81:
Also, I forgot to mention, all four bolts were not even finger tight. ;D
MP81:
Started disassembly:
Air horn removed:
Main casting with the air horn removed:
Gasket removed:
Accelerator pump - seal does look mostly okay, I think:
Main casting components removed:
MP81:
Well, looks like the plugs were removed down here:
Throttle plate removed:
Fuel bowl plugs have already been epoxied in the past:
Throttle plate gasket removed:
I need to do a quick soapy water test and see if the bowl plugs are leaking or not, but the epoxy looks to be pretty solidly on there, so we'll see. Everything is really quite clean inside. Nothing seems gummed up - everything moves quite easily and freely.
MP81:
Some other detail pictures:
The first one: some plunger on the underside of the air horn?
The second one: The accelerator pump seems awfully springy and wanting to pop out of the casting - this normal?
MP81:
First one: Power piston?
Second one: So I took this out, and it looks like the rebuild kit has a similar part, but with some kind of plunger in there? Mine does not have that. It also doesn't have the slots like mine does.
