of course a carb problem.sorry

[powerram50]

ok i have had nothing but problems with my carbs.i have them all cleaned and bench synced and i think the floats set right.#4 carb when i turn the fuel on starts pouring gas out all the vent holes on the air cleaner side.i checked the float and it does not have a hole.the needle is clean.it is set the same as all the other carb's and the float level is perfect on them.with the bowl off and moving the float by hand and blowing into the fuel line the needle justs off my air that i am blowing thru.what is wrong with is i am tired of these carbs and want to ride it.i have drove it 5 miles since i bought it 2 1/2 months ago.

What type of float valve seats do you have? If they are the type that have o-rings (NOT the threaded type), fuel will leak past the o-rings even if the needle is fully seated. I had the same problem with mine leaking fuel out of the air vent hole. O-rings are readily available from auto parts stores...just make sure that you get thetype that will hold up in gas.

your float is probably getting stuck on the side of the bowl or the float is falling too far and letting the needle valve get jammed side ways. If you do a few searches you can find the pictures of the needle valve falling to far down.

Basically you want the float to allow the needle valves to only fall a mm or 2, any more and they can get jammed.

Someone else said that their gaskets were a little to wide and the floats were hanging up on the inside edge of the gaskets.

i am thinking of sticking the needle and float into carb 3 then if 3 leaks i know it is the needle or float.becouse when the carbs are off the bike it seems to work perfect.

so far so good. neither leaked.it got to dark out side to check the the float level.i will try to fire it in the morning.i just got done charging the batt.

Make sure the seats are super clean where they sit.My #2 carb leaked out of the same holes .I took off the float and took off the seat.Underneath was a bunch of brown sludge that definitely was clogging the little screen.I replaced the seats with new ones after cleaning out where the sludge was.I also sprayed the new seat with WD-40 and popped them in.I think that if you try and put the seat in without lube it might do something bad to the o-ring.I have not had a problem with that carb since i replaced and cleaned out the seat.

it will run at full choke but if i take the choke to 1/2 it dies and wont stay running.

[powerram50]

runs like crap and only with full choke but i did put 7 miles on it.i could not help myself.

[oldyam80sg]

I would think that the carbs still are not completely cleaned.I had to do mine at least 4 times.IMO

If you clean the carbs again, check the spooge hole in the bottom of the carb bowl. That was messing up my idle and making it hard to adjust. After cleaning my carbs multipe times I didn't know it was there until I was told about it. It is at the bottom below the vent hole that lines up with the hole in the gasket.

i will take a look thanks.i put another 13 miles on it tonight.got it up to 75.
