Hi! Thank you for reading!
I have an issue with my Bella. '94, 903ccm, "electronically controlled" Weber 32 ICEV.
The symptoms are like this: when cruising, or getting up speed, she starts to stutter(/twitch?), like she gets no fuel. If I step off the throttle and roll some with "enginebrake", then step again on throttle she goes again, then starts to stutter again.
Or I clutch in and roll, rev the engine some with some throttle kicks, step off the clutch and go again then she goes again, then 5-10 seconds later starts everything again.
She does this for a 3-4 times, than she goes well again, for couple of miles.
Than stutters again. Sometimes even clutching in and revving does not help, the engine stalls. Then I have to use the starter for quite a while.
I replaced the carb gaskets, some O-rings, booster diaphragm, checked the fuel lines, checked the fuel tank (at least fuel gauge works now again ), changed fuel pumps diaphragm, but still does it, even with full tank.
I have a VAZ/Lada fuel pump on her from the beginning (84400km and 2013). Now she has 125900km.
With the VAZ pump she goes at least, but lately as described. The original fuel pump pumps nothing, though it was re-newed. :S
Fun fact is that I had a trip to Austria from Hungary (my home country), and the trip there was about 440km's, but she haven't done this on the way there, not even on highway where tempo was constant 110km/h, and had some many km long uphills. But before, and after she misbehaves, sometimes quite frequently.
So I start to get clueless.
Suspects are the fuelpump pushrod/camshaft combo, fuel pump, and the floater(?) jet (the one with the ball valve) I got with the repair kit for the carb. The original is 200, and the kit has a 150 jet, but I left the original in the carb.
Anyone had similar problems, or heard such? Would be great if she'd run well again.
