My pump works fine but my carb is not squirting fuel.what gives my carb should be pushing fuel down the intake but isn't.Any ideas?damn weber https://www.nopistons.com/forums/pub...1047683358.gif It gets fuel to the carb

does it have a filter screen on the carb inlet? maybe a stuck needle and seat?



mike

Everything looks and works on if beside it not pumping fuel in.It came off a running car.Is it possible that I need to dump some fuel down the intake and prime it off it?

How long was the car that it came off of sitting before you pulled the carb??

If it was more than 10 days or so try running carb cleaner through it with a pump. Get the gallon jug type stuff (acetone and something) it will be at your auto parts store. If that dont work try a chem dip.

If you really think it the carb.

Could be accelerator pump.

I'll try carb cleaner on monday.I'm not sure how long it has been off a car for.I've had it a month and never used it yet either. https://www.nopistons.com/forums/pub...1047683358.gif

Would trying a pull start help give the carb a boost to start it up?I heard it helps rebuilt motors.

Yea thats definitly my method but if the jets are stopped up it will run like s#!T. If they are real bad off it probably wont work.....but Id try it for sure.



If you try to use a pump and carb cleaner, try to get ahold of a fuel injected pump. It will probably be submersible but it will be 50 to 100+ psi. It will definitly blow the trash out.



What made you change carb?

I was offered the right amount of money for the dellorto.So I sold it and bought a weber.Now if I can get it to run that would be nice

when you turn the key on does fuel come out of the fuel line?



mike

Yeah.The pump works and fuel comes out.I'll try a bomb start and see if that helps.After it quits raining. https://www.nopistons.com/forums/pub...IR#>/angry.png

you should take the cover plate out and see if the needle and seat works and how the jets look. of course the jetting could be like so far off it wont run but we'll assume its just bad/dirty



mike

Try to get ahold of another stock carb, If it works then you know its just the carb(probably floats and seats) but if it doesnt work then you can look for something else.

If you were running a delorto how big is your fuel pump? Too big maybe? Could it be sealing something from too much pressure?

I was just looking at carb jet prices for the nikki. Man they are cheaper than I thought. Im gonna have to get some new ones if they are that cheap.

Bombed it at 50 km/h and still no go.This carb was new with 10 hours of use on it before I got it.Any ideas?I want my NA to run again.I shouldn't have sold my dellorto. https://www.nopistons.com/forums/pub...O_DIR#>/11.gif God damn webers https://www.nopistons.com/forums/pub...IR#>/angry.png https://www.nopistons.com/forums/pub...1047683358.gif

Just tried the fuel system and I coverd the carb in gas so It's getting fuel just not spraying it.Any Ideas????????????????????????????????????????????? ??????????????????

mike
