Fuel flow problem? By porchman (Read 2,183 times)

[porchman]

success dis-reassembling and cleaning the carb, thank you. it was really quite clean, may have been some crap in the main jet, when i was younger i might have been able to see better.
it no longer gags at all when i give it gas.
two items that i need further advice on:
1 - full throttle isn't as wide open as it was before, like about two-thirds...?
2 - when i cut off the engine, gas comes out of the carb drain hose. i tried to re-align the needle valve on the floats, it looked ok to me...?

Do you mean turn the key off or shut the throttle down? Your float valve isn't closing. It's a tricky thing. Can you get us some pix?

I know guitar,,, he's worse than I am,,, that's f@()d up,,,

[porchman]

Bashan, it is when i turn the key off. at least i think so, i ran out of daylight yesterday.
i will try to adjust the float valve appropriately.
i tried my best to not maladjust it during cleaning, but i guess i failed.
is there a special trick or guideline? i just re-hooked the fine wire at the back of the needle over the tab that sits in between the two plastic floats. like maybe it's on backwards or something? i will be able to take and post pics on saturday, hopefully, if still needed.
ongoing thanks for all the assistance, it is much appreciated.

Yep. But, (Ha! I said Butt. LOL) I like the derriere. On women you understand...

The important thing is to make sure that the fuel inlet where the gas comes in is clean as well as the tip of the NEEDLE valve so that when the float moves it up it seals and stops the fuel from coming in when the BOWL is at its proper level.


And here is how to set the FLOATS for proper fuel level in the bowl.

[Guitarman]

I did not know how to adjust floats. Thanx!

[porchman]

yet again, perfect advice.
i think i've got everything back in place, no leaks, the float needle seems to work right, etc.
starts easy, idles fine, doesn't gag when i give it gas.
full throttle, though, remains a problem, and i'm only getting about 60% of former top speed.
it seems to reach max after only about a third of the way on the throttle, and the rest of travel as i twist back seems to have no further effect.
gracias....

Partial blocking of the main jet Alley?,,,,, small hole in diaphram,or small tear? so the slide is not at it's "top" when at full throttle?

VALVES! LOL (one of the most common answers here)
