I hope your new float solves your problem devonalcorn. I'll have to look at mine. I did, however, already check the main jet and it was ok (not clogged or loose, etc). And now, the slider won't hardly move up and down in the chamber at all at any position and takes quite a bit of force to get it down in there... I'm about fed up with it.

Aiko... there's a slot in the side of the slider that fits over a tiny brass pin down in the carb body, (to keep the slider straight)... If you missed the pin, the slider will stick!
also, another thing to check, is that the cable isn't kinked or has any sharp bends in it.

It originally worked fine. I took it out to look at it and it wouldn't hardly go back in without quite a bit of force. Before it even gets to the pin. The slider I mean. |

You have a cloged muffler take it off and try it if that solves the problem then clean the baffles. Phoenix JIM |

Venice boy - excellent advice!
@ the OP - if you have done/looked at what VB has suggested and you still have issue,
I ll link this here as well Carburetor - Wikipedia, the free encyclopedia (ive got the link configured to shortcut to the section of interest for you & this problem )
What you mentioned in op : Runs great until rpms get higher
means you have a jetting issue. Check out the link above, and pay attention to "Power Valve" section of the Operation block. NOT what i would have referred to it personally, but its a matter of terminology.

As it would turn out, I bought a new carb and it solved the problem. Even on it's leanest setting, moving the needle didn't help at all. I guess the jet in it was just too big. New carb is a little rich as well, but I think that moving the needle on it would help. I'm gonna leave it that way until I break the engine in anyway. I appreciate everyone's input. |

I appreciate everyone's input. | Man oh man, am I ever NOT enjoying my recent first-build. It is gutless with little to no low-end power and NO top-end power. I endure sputter-sputter-pop-cough-cough-puff wherever I go. It is hard to start, and dies easily. I have a new float, cleared jet, loosened throttle rod, etc. I have taken the carb apart and checked for soot, and whatnot. I am not pleased, BUT I will admit to not having cleaned out my brand new muffler and have not reset the factory clip on the throttle needle. I am running regular gas with an oil ratio of 16:1. I am barely into my 15th mile of miserable driving.
I hope this gets more enjoyable.   | | Thread Tools | | | | Display Modes |  Linear Mode |
