Excellent. Is there a relatively easy way to check the needle or the screen and clear them?
Can it be done while carb still mounted?
Thanks again

Re: Gas tank suction
I have a weber DFEV 32/36.
Just went through the trouble shooting guide but saw no mention of the needle and screen. I see the DGEV has a fuel filter inspection plug, but not mine.
The carb is relatively new with about 2 thousand miles on it and has worked well until now.
Hope those details help.

Re: Gas tank suction
This has evolved to be a different thread. I'll re post if I don't get this remedied this morning.
found the screen and cleaned it. There was some tiny debris in there but it was no wherenear blocked. Screwed the cleaned screen back in and still no start.

Re: Gas tank suction
First of all, Tim, let me just say that I feel your pain! I get frustrated with the learning curve on my cars too.
Let me get a pet peeve out of the way. Everyone wants to pull the plug wires, find a used/new plug, test spark by grounding to the block. This works, but why do it the hard way? There is this neat little tool called an inline ignition spark checker. It is only $5 at the local Harbor Freight here, and I can't imagine it would be much more at the local parts stores. IMO, it gives you a much better visual to verify spark with the added benefit that you still have all four cylinders firing. Whew, glad to get that off my chest.
If I read correctly, you have fuel flow from the pump up to the carb but couldn't see any flow in the venturi. You've found the inlet screen and cleaned it. I would have to agree with asruss that you have a stuck needle valve or clogged jets. It may turn out that your running issues have nothing to do with the venting of the tank. Still, that does need to be adressed.
Looking at your pics, isn't it amazing what previous owners do to our cars??

1 - Because a fouled spark plug can generate a spark in those things.FiatBen wrote:This works, but why do it the hard way?
2 - Because that's how my dad showed me.
3 - Because in 25 years of working on cars I always forgot to buy one of those things and remind myself of 1&2 when I am being shocked.
