difficult to start when hot

[kajsdf]

jurjen, how did you set up the return line? i noticed the carter had a funny insert on the connector, and i am unsure of its purpose.

[Jurjen]

The return line is on the filter, you will find the fuel return line itself somewhere near the shock tower on drivers side.
The return line itself has a non-return valve that is opening from filter to tank.

I've had cars do that before too...they start in the coldest weather but try to start it after driving an hour and forget about it. It almost acted flooded....I could smell heavy gas fumes when they did it. One of em turned out to be the wrong gas cap and it wasn't
Venting properly.

that thread was quite helpful and it sounds like it's going to work -- however nowhere in town stocks a 1/4 fuel check valve. i found one on the 'bay for 20ish shipped...if it works, that is well worth it to me, but do you have any other part suggestions?

[Jurjen]

Nope, just a three way filter, a check valve and fuel hose to hook-up the return line.
Check the rubber hose near the tank too, it may be old and brittle.

Do you have a part number or possible location for the check valve? nobody in town stocks them but i found one on the auction site for about 20 - is that reasonable?

[Jurjen]

As you can see I'm located in Europe.
The valve I have, will cost $16 on the famous auction site in the US.
The famous auction site in the UK has them for 4GBP!
Normally car parts are much cheaper in the US.

completely forgot you were in europe - even though i knew that already. 

the picture in the posting looked exactly the same as yours, so i figured that was it. 

thanks a bunch...you are a treasure trove of valuable eagle knowledge...and i am sure much else...

completely forgot you were in europe

I take that as compliment 

[kajsdf]

the results are in -- the check valve alone did not solve the problem.  when getting gas the other day, i got the "soda can" hissing sound mentioned by mudkicker and rohnk. it was not present before the return line was re-instated...

which leads me to believe i have a multi-part problem...previously, i think the tank was venting thru the return line somehow, but there was still too much pressure which flooded the carb.  now, the return line doesn't allow this which gives the excess pressure at the cap.  is this due to the cap not venting properly?

[mudkicker715]

So is hissing vacuum or pressure¿

[kajsdf]

definitely pressure - if the cap wasn't screwed on, it would blow itself off...but......i think i just solved the problem....


apparently when i installed the 2100 i just set aside the return hose because it was crimped to the return line and i intended to deal with it later.  when i reinstalled the return line, i was hooked up to the smaller of the two lines going to the tank -- apparently one of those is a vent...i think you can see where this is going...i didn't even think about the other line because i had the hose tucked away somewhere so i thought it was attached to something else.

frankly i'm ashamed.....

[kajsdf]

it still seems to have trouble starting up but it doesn't seem to be as bad - i rigged up a hose from the vent line out the grill as a temporary measure to get everything non-vapor out of the line...i know it's working because the hose reeks of gas, but it probably just isn't empty yet. no more hissing from the cap, though...
