An Idle problem

[AlphaRunner85]

Pre-thanks for any help on this. I have a gokart with a
5 hp briggs funpower with a diaphragm carb and i will only idle at half choke. ive adjusted the idle screw almost to the point of removing it the diaphragm is in good shape and barely a year old. the screen on the long dipper into the gas tank is clean and the stubby bit that looks like a valve of some kind looks in good shape also. im workin on pics that would probably help.

Blow some air threw the passages.

I did and it flows pretty well for the size of em.
As best as i can tell everything flow pretty well.
I dont know if my particular carb has a float
and when i stripped it down the first time i
didnt see a float and there are no loose parts
in the tank.

Is it a Briggs flathead? Pics! Take them!!!

 

[AlphaRunner85]

Yes it is a briggs flat head..... And photobucket cant
see my pics to upload them.

Your carb doesn't have a float, it get fuel it pumps it with the diaphram from the tank to a small bowl where it then pulls it into the carb. To keep it from forcing too much fuel into it, it has an overflow.

Does it run without choke at WOT?

ok so i found out i have a pulsa jet carb and no past half
choke it dies almost immedatly

Is your intake gasket still whole? No cracks or anything on it?

 

[AlphaRunner85]

almost all the gaskets are new and the engin seems to have good compression.

i have the same prolblem with a robi weedeater engine 31cc it will only run at half choke you take choke off it kills it

it needs more fuel...bigger main jet. thats why i hate the epa, if only engines could still have hi and low speed adjustments.

Problems described are not EPA related.

So have ya ever just wondered how some people can just touch stuff and make it work? I stripped the carb down and cleaned it twice, and adjusted everything i could find and My neighbor fiddled with the @$#^%$ thing for TWO min and it runs like a freaken race car.

no but they'd be alot easier to fix without the epa
