Tomorrow is an exciting day, I try and get the opel 100% functional! It's been sitting about 2 months and I'm ready to go ham to have it drive once more.
unfortunately the float bowl isnt filling up with gas at all, I got it to start and run ok when i poured gas into the float bowl as well as running off of purely starting fluid. however i'd like to have everything go properly. I'll tell you my plan of attack and let me know what other suggestions you have.
So first thought is that the fuel line is plugged or just doesn't have a lot of gas in the line at all. I was going to open the fuel door and just suck on the hose trying to get anything to come out. It doesn't sound fun to be honest.
For the fuel pump i though about taking a glass of gas and connecting that to the pump to see what squirts out.
For reference its a 1.2s* Opel OHV motor out of an Opel Ascona B

Try smacking the float bowl with a screwdriver handle. Needle and seat may be stuck.
AND IF NOT A STUCK FLOAT REMOVE THE FUEL LINE,HOLD YOUR FINGER OVER IT AND SPIN. SOME FUEL ISN'T ENOUGH A GOOD PUMP WILL BLOW OUT FUEL WITH SOME PRESSURE APPLIED TO THE END.
PUT SOME FUEL IN THE FLOAT BOWL BEFORE TAPPING IT HELPS TO MAKE IT RISE UP AKA FLOAT
An when that fuel that blows out meets a spark plug, we will know for sure that the pump works.
Run the fuel pump outlet hose into a glass jar (you can swap a nice long piece of hose and set it on the ground), that'll answer that question pretty quickly.
If the needle and seat are something you touched in the rebuild process, it's pretty easy to bend them and cause a problem (ask me how I know...), so don't be afraid to pick up a spare or two and try that if the fuel pump works.
First: Do you have fuel coming out of the fuel hose at the carb inlet with the engine spinning?
If so...you have a needle/seat/inletfilter issue.
If not, you have a fuel supply issue. Fuel Pump, lack of gas, leak in the line, filter, etc. Do you know there is fuel in the tank? Can you blow air through the fuel line from where it attaches to the pump?
So, hate to say it but I disregarded everyones advice and took my own route!
still works! fuel pump has to have gas IN it to work. lesson learned
