Chris_Oz:
Hello all,

I would like some advice on which way to go with repairing or replacing my Qjet.

BACK STORY:

STOCK 1970 Chev C20 pick-up, 350 sbc, manual and stock other than a HEI distributor, 34 deg total mech and 18 deg of vacuum, manifold vacuum.
Carb id 7040208, correct year, but mine is a Cali truck and manual, not Auto

Truck was rich and flooding.
Had 75 jets and 39/26 rods, which is federal spec for that carb and year.
Very rich at cruise. Float was fuel soaked and not shutting off, so time for a rebuild.

Rebuild done and carb running fine, 20inHG vacuum at idle, still rich on stock jetting so I fitted some 71 jets and 45/26 rods, as this is the spec from a chev 68-69 350 truck.
Runs much better everywhere, now has 21inhg at idle and 16-17inHG at 55mph on flat driving, I have the heaviest (strongest) power piston spring in, it starts to lift at 11-12in hg, I cant get an accurate reading at idel when its fully raised, but on road it feels like its all the way up at 9-10 inHG, if I go lighter on the spring, it has a slight hesitation on light roll in throttle.

Pretty happy with the tune and how it drives, it is a play toy, not hauling loads or working hard, gets used as a daily drive and weekend cruiser, so reasonable fuel economy is a factor.

Now the bad part.

The fuel inlet is stripped, it was weeping before the rebuild, it had a very slight wetness, but is now stripped out and I am in 2 minds what to do.
I am in AUSTRALIA, shipping to send out for a repair both ways, with tax and import charges will cost me more than a new carb, so its not a viable option.
The fuel inlet fitting I have only has 0.280

Chris_Oz:
The carb has just over 0.500

Chris_Oz:
I have no idea what is going on.

It wont allow me to post a whole message, shows in preview, but only posts the first bit.
