Default Re: have REAL power loss now!

Thanks for the help deacon. Sounds like I am doing all right on everything so far. Norman is going to look at my old carb and see if he can fix it. It had a ton of power but I don't know if it was from the extra gas that was leaking. I know that Norman is the man around here so if I can get him to take a look at my carburetor I will be doing good.

Yea my throttle responds instantly pretty much. I'm going to look into my carb some more today when I get the time.

thanks for all the help,

If your engine responds instantly to the throttle then you are fine. It there is a some slack not in the tension but in the engine response I would tighten it. If it responds instantly then I wouldn't bother with it.

If you didn't find a leak and your throttle responds, you are past anything I know to do. Try Norman he knows everything about these engines and carbs.

by the way the pressure you feel on the throttle when the slack is out is the spring not necessarily the needle moving I think. At least that is what it was on my diy bike i worked on today.

When the needle was actually moving the engine responds. It ain't much but it's the best I can offer.
