So after i have found some bugs in my q-jet i have another one. Nozzle drip from only one side, driver side it is. I checked throttle plates and they are both same, iddle circuit is clean, float is set to 5/16. Is it warped body or internal vaacum leak? Thanks for any input.
You're from Poland, why don't you convert your Riviera to run on LPG ? It will save you a lot of money in petrol costs, and you don't have to worry anymore about the problem above :TU:
Hi Erik, we have been talking about it before. First i don't like LPG fumes and second it's historical car so i can't modify it that way. It's also not a daily driver so costs aren't killing me yetray:.
what is the Qjet ID number and is it a nailhead engine? does the qjet have the appropriate idle air bypass holes and are they free of obstruction? check all the air bleeds and orifices for obstruction. could the primary throttle shaft be twisted a bit such that one primary has more throttle opening than the other? This would increase signal to that side's booster. an overly worn throttle blade or baseplate bore would have the same effect.
I see you Erik, take my apologies..... ---------- Post added at 01:40 AM ---------- Previous post was at 01:30 AM ---------- 7041308 and yes it sits on a nailhead. All passages are in place, ones in the gaskets aswell. All bleeds are clean, shaft has been checked with straight edge, bushings are in place so no vaacum leak there. No visible signs of destruction on plates nor on the bores. I noticed one strange thing, when i use compressed air to blow thru idle tubes, the one which has nozzle drip also gives strange sound. But when i stick Mig wire there, it comes thru easy. Idle tubes are new from Cliff's.uzzled:

You could try increasing the initial timing, then back down the rpm screw (drivers side near linkage). Backing down the screw closes the throttles and should cut the signal to the booster. Another thing to troublshoot would be too much fuel pressure. Also is the gasket stack correct? Is a heat shield required for this intake? Also check operation with and without throttle linkage attached. Good luck
Looks like i sorted things out. Little press work on body and air horn, and no more nozzle drip. Carb finally reacts to that little screw, the one for idle bypass. Idle screws are 1 7/8 turn out and buterfly stop is about 1 turn in. No more erratic idle. Thanks for all suggestions guys. Peace Kacper.
Might try raising the float, those older carburetors don't have much fuel in the bowl with a float setting that low.....Cliff
Cliff i have been trying with factory setting but 3/32 is to high. Carb has been wet than. i'll try how it will go on 3/16 maybe.
