Thought it would be an easy fix, but even when I manually try to throttle down, it still is running at max rpms. I turn off the key to shut it down quickly each time, but I"m perplexed on what to do to correct this. Any help would be greatly appreciated. [Reply]   [No Email]

Once ya get the carb off the "N"......As SouNdguy said,...look down the throttle bore and see if one or Both of the screws are broken or missing. that would be my guess!!! If that is the case, the throttle plate is cocked inside the bore. and will NOT release the rod until you straighten the plate. Get something with a small hook on the end, to try to pull the plate up and straight, while keeping a slight pressure on the rod bail. If the rod or plate gets bent...(Only made of brass), then you will have to buy a New plate and rod!!! GB :!: [Reply]  [No Email]

I disconneceted the gov too carb and manually set the carb-no luck, it still is running at wide open throttle. I was not far from home, so I "feathered" the choke to get it in the barn, but still extremely high idle. [Reply]  [No Email]

I removed the carb and the flapper seems fine-opens and closes when I do it manually. It seems to ba attached and functioning properly. [Reply]  [No Email]

But after re-reading your reply and looking at it a little closer, what appeared to be rivets holding the flapper on were actually screws that had worn out so bad that the head of the screws would let the flapper slip up and stay open. I found a shaft and screws on an old one at the local tractor place, bought it for $5 and put it on. Works like a champ-thanks to advice from guys like you. I can't tell you how much I appreciate it. You don't know how much time that saved me. Thanks again for your sage advice. [Reply]  [No Email]

The other day someone knocked on the door and asked me if I ever thought of the "hereafter". I said yeah, every time I go into a room, I think, "Now what did I come in here after?" [Reply]  [No Email]
