Cliff Ruggles:
I've tried to watch a few Youtube videos on building Q-jets.  I can't get thru more than a minute or two of them without getting ill!......

Kavesh:
Lol, Cliff, I know what you mean. For someone like me before finding this forum and chatting to people like John Herald Jnr and a couple of others, it was my only source of information.
You have to watch dozens of video and extract bits and pieces from them.

 

Kavesh:
Anyways, back to my issue, will a open needle and seat cause the amount of fuel in the baseplate per pic in the post above.
I would want to reuse the main body if I can as its the best float bowl I have.

quadrajam:
I have seen that same fuel syrup in that same cavity with no running issues.
It is surrounded by gasket and any fuel that weeps by the gasket would be
very slight.
Prolly was debris in the needle/seat. Clean it all up and new kit. Check that
fuel filters are OK.

Shiny:
Check the seating surface under the fuel inlet seat.  Mine was rough from corrosion and/or prior grit-blasting.  It wasn't obvious, but it leaked a little until machined flat again.

I also had flooding I attributed to rust in my fuel sender.  The particulates were obvious when I opened the carb, but were small.  I think it may not take much debris to cause seating issues.
