Continuing my saga……..(from the realm of electrics to fuel)…………

Is there a proper way to adjust the float in the (toilet) carb bowl? Easy way?

Right now I have Norm's chalk board warning! (Yeah I know

) A factory setting that didn't work. Heavy fingers and needle nose pliers.

To Recap:

1) Factory setting, suspect float too low - not enough fuel ready to go. Open slide via twist throttle - too much air, not enough fuel on immediate demand. Not a matter of too rich or too lean.

2) Open carb up, tweak float "arms" apart. (see Norm's drawing). Problem gets worse.

3) Open carb up, tweak float arms together. Get Exxon Valdez of premix fuel in the garage.

4) Open carb up, tweak float arms apart problem still there, but better.

So today, this afternoon: Just bring the arms together a hair……it's a fine line and I need some input……..

Paco and his faithful black dog Chancho thank you immensely.

It's all in good fun. Gets a little irratating taking the carb off and taking ultimate care of the bowl gasket....but still fun getting my butt kicked by this sucker!

Well, you are on the right track thinking of it like a toilet bowl.
How about trying this:Take carb off, take it apart, hook up fuel line ,hold carb level and bend float until fuel level comes up to gasket level or a touch under.

Kinda what I tried when I did the spill....but it's a great way to see that the float valve is working. It's a bit difficult to eyeball. Maybe I should have a clear bowl fabbed

Don't you have a buddy who has one of these engines? Borrow his carb and try it to see if the problem goes away. You could send me your carb and I'll give it a go make it work on mine then send it back to you. heck box it all up and I'll get it to run or shoot it and put it out of its misery.

OK so I came home and adjusted the float, just ever so slightly UP (float higher, arms together) - wholly crap it runs MUCH better I mean I was revving the caca out of it - then after it's fully warm choke all the way off still running good, getting warmer and hit the throttle hard booooooooooooooooooooooooooooooooooooooooooooooooo oooooooooooooooooooooooooooggggggggggggggggggggggg ggggggggggggggggggggggggggggg AND dies.

POINT = I'm getting somewhere! Just ate, need to have my cheesecake then take the carb off again....

Pablo did you say your mag wasnt tight on the woodruff key?? That could sure cause a timing issue and it sure sounds like you got a timing issue................
