There is a rubber seal on the carby neck you never know you might also have a leak from there and that's easy to change when the carby is off.
Hi Converse,
Ref the attached "Carburettor Exploded". I have replaced (For different reasons as well), 3, and swapped 14 with the Red spring. The diaphragm appears to be functioning normally. If it weren't, when I sucked on the vacuum hose connected to the diaphragm cap it shouldn't create a vacuum, which it does.
Ref the attached "Manifold Exploded", I've replaced 31 & 33.
Ref the attached "Starter Exploded", I have replaced 52.
Can you still adjust the revs to fast and slow speed with the throttle control lever?
Yes, but only to a very small degree, there isn't a very big difference here between the start, idle, and full positions, but there is a difference.
Some years ago I did come here for an issue on my mower where the idle speed was too fast on my older full crank Victa with the G4 carby, I got some great help here and added a few brass washers in the carby and it fixed my fast idle issue.
Ref the attached "Carburettor Exploded". You're referring to the washer, ref 8, is that correct?
I haven't tried anything here, unfortunately, I don't have any available to me at the moment, but I can try this. I have always been curious about it though... why does this make a difference? I understand mechanically why, but I'm assuming this isn't something that occurred initially but came about after production and after use. So is the cam rotating on the carburettor body and wearing it down over time, causing the seat on the carburettor body to wear and therefore requiring repair essentially?
Cheers in advance,
Paul
