Took ICT34s apart...

  1. Could be - when I first had the problem, I bought new gaskets but they got wet soon after. I wonder if I should be just pinching the screws up. Euro carb say the gaskets should get wet during normal operation, but not like this.
     
  2. Are the two surfaces perfectly free from old gasket? I am sure they are but worth a check.
     
  3. I will double-check. Am putting an order in for new gaskets from Eurocarb now.
     
  4. Slightly off topic, but still fuel related. I was out for a run and everything was fine. Once up to temperature I noticed a bit of a hesitation on acceleration. Thinking I might need to tweak the carbs a bit more, I opened the engine bay, once back home, whilst it was still running and found the filter bowl on the regulator was really low.

    It got lower on tick over. Running the engine higher did not seem to fill it up much by any decent speed. At one point I thought it might run out. Fuel pump issue? I'd swear it was full this morning.

    It's all go isn't it? :)
     
  6. You are not wrong! Better news is that the right carb showed less signs of leaking, so hopefully new gaskets will sort it.

    Fuel pump dying/needs rebuilding?

    Sounds unlikely if you are having to regulate it. I have one without glass - one less thing to worry about. :)
     
  8. Went to check engine before putting bus away and the filter was ¾ full again. This if course dropped when starting, but I could see fuel coming in. Perhaps this is normal!
     
  9. Got new gaskets and after fitting found that the front part of the new carbs are not pinching the gaskets. Took tops off and put them on a granite slab. Looks like a manufacturing fault as they are clearly not flat and that is why they are leaking. I will try to send them back.

  10. Eurocarb have offered to change the tops.

    Cripes! So they should!
     
  12. you could flat them yourself but that much is going to take you quite a while! that's terrible
     
  13. That is shocking quality control
     
  14. I have an instant fix for you mon ami ....

    ICT's are so simple that they're less trouble than that. I've just done the swap this evening on my super-duper-1600. :thumbsup:
    The answer might be to get 2nd hand originals, like every other carb.
     
  16. Tried something new. When switching off the engine, I switched on the ignition again for about 30 seconds to allow the aftermarket fuel cut-off solenoid to stay open for a bit.

    Not seen the gaskets get wet with fuel the last two trips out. Fingers crossed.

  17. Very sorry to kick this off again, but I still have the issue of the gaskets getting wet after switch off.

    I have by-passed the 3rd party fuel cut off solenoid so everything is stock setup as I thought that was the issue.

    I have been out for a run and waited for the carbs to show signs after switch off and checked them. Both carbs, even after 10 mins, still showed fuel on the closed butterfly. Then I noticed the pump jet dripped fuel.

    Could this be related? I could still see fuel vapour in the right carb for around five minutes as well. If I blew it out, it returned.

    Cheers
     
  18. Eurocarb have suggested a one-way valve - hopefully this time...
     
  19. Do you have the bakerlite spacers under the carbs??
     
  20. I have spacers supplied by Eurocarb. They are compressed gaskets by the look of it and I got them to stop the fuel boiling. Now the carbs get condensation on the outside, and it is definitely water. The carb middle gaskets do smell of fuel.
