Rust , What Rust !! I don't See any rust !!!


« on: 27 April, 2014, 07:03:33 PM »

I have developed a problem with my Fulvia, It starts up no problem and then when put under load it miss fires and chugs along. I checked the fuel flow and filters from the tank , the points , the timing and changed the spark plugs ! it ran a bit better when I changed the plugs but it s still not right. The temp wont rise to normal running temp, and then it runs smooth for no reason at all  !!  Huh?, Iif I pull the choke a little it seems to run better . Could there be a blockage in the carbs ?  Its wreching my head to fugure this out ! Any ideas ? Thanks David. Undecided

Have you checked the "micro" mesh filter on the inlet union on rear carb ?

I had exactly that on my augusta, gauze partially chocked so the carb would run out before it could refill

Does sound similar to the carb problems I had on my Beta. That was dirt in the float chambers, jet feeds and the jets themselves. Cleaning the jets was a temporary fix, but further dirt would then be dragged into them from the float chamber. Only a total strip and clean ou,t with everything blown through with an airline fixed it.

Easy to check out Peter's condenser suggestion though.

Does sound similar to a condensor breaking down. I had something like this on my Fulvia years ago - as you say, like a bag of nails, spluttering along, running rough, and that's what it was. For the price of a new one it's worth a go

And do the points at the same time! Either fit new ones or stone-down the old ones to take out peaks and pits. The last set of points I did had massive pits, about 0.3mm deep. A defective condenser can cause this sort of migration of metal from one contact to the other.

Thanks for the advise, I fitted a new coil and HT leads today and its running perfect Cheesy, Amate of mine suggested the coil and i got a Bosch one and replaced the Intermotor one that was bought new in 2009 while I was restoring the car. I thought I was covering all the bases by replacing everything at the time, but time goes by very fast and five years has gone by in a flash. I am going to replace the distributor with a new electronic one from Omicron . Has anyone tried this replacement yet ? it's expensive at 280 plus vat , but the car has cost me very little since the restoration . Thanks. David. Smiley
