1250 Engine Trouble
 

Looking for a little help with a 1250 Quiet line Cub. The trouble is with the engine. I can start the engine and engage the mower deck and let it sit in place and it will run fine but, I start mowing and after driving about 60 feet the engine will sputter then just shut down. I can restart the engine right away, but when mowing it will still shut down. I have replaced the points and condenser and it is still doing the same thing. Please email me at: apollo57@ptd.net Any help would be appreciated.
Thank You

Does it run better if you pull out the choke?
If so, time for a carb rebuild. ...

You are running out of fuel even if you have a full tank. Could be carb or some restriction in fuel flow from the tank..... My guess is the later. Too low a fuel flow to carb.

Carb has been cleaned and rebuilt, fuel filter has been replaced and new spark plug installed when problem first surfaced. I know the older "K Series" engines had issues with valve adjustment. Is it possible that might be my issue?

What fuel filter? :bigthink:

Pictures please. We like pictures. :ThumbsUp:

Not to hijack a thread, but,you folks don't run inline fuel filters?

I agree with the previous posts. Sounds like a Fuel Delivery problem.

My experience is that adding an inline filter to a Quietline will cause fuel delivery problems. The screen in the tank is more than enough filtration.

What I want to know is why do we have to email Mr Whipple? :bigthink:

Mr. Whipple squeezes the Charmin, he is "Different":biggrin2:

That is true IF...........one uses the wrong type of Fuel Filter.
