How do I fix the tapping sound from the engine when i accelerate after it has reached running temperature

Adjust the valve tappets (yes, they 'tap') AKA Rockers or find out why the hydraulic self adjusting tappets don't work?

They transfer the downward motion of the cams on the camshaft to depress the valves. There is a thin clearance of about 8 thousandths of an inch with the engine cold. As the engine heats the clearance reduces. Over tightening causes the valve edges to burn, too much clearance causes tapping.

Manual tappets get quieter usually as the engine heats. Hydraulic tappets gets worse as the engine heats as the oil thins.

Needs specs tap pet clearance timing specs can you help please

Hi Sandra:
With hydraulic lifters (tappets), I've set them "by ear" by backing them off (with the engine running) until they start to click, then snugging them until the click stops. "Old school", but has worked for years for me.
You'll need to give us make and model to be able to try to help with the timing.

After my mower gets hot it makes a ticking noise

It really depends on where the "ticking" is coming from. Was the ticking there before the leak was fixed?
If it is an 04 model, it is 10 yrs old. How many hours? Try to determine if it is coming from the area by the valve covers. You may have a tappet clearance issue. Check the clearance between the tappet and valves, check both sides (Twin 18 hp?). If any are out that is where the ticking is coming from. Could also be a worn cam, but sounds like a valve tappet problem.

Tappet clearances when hot

Tappet clearances are always done cold...these clearances exist to account for thermal expansion of the valve train

I have no spark i think it might be my cdi starter turns over but it wont start it sounds like its dragging

Check if any spark comes out from the spark plug.
Try to remove the airfilter and choke the carburetor when your starting the engine.
Hope that helps you!

I have a 50cc moped qt jinlun i just bought anew carb when we start it, it run for a while then just dies as if starved of petrol i know it works by a vacuum it will go down the street for a minute then...

Hi and welcome to FixYa,

To my understanding, most of these China made scooters uses a vacuum controlled cut-off fuel valve. Vacuum is tapped either from the carb out or intake coupler to activate and allow fuel flow; no vacuum no fuel from tank. Possibilities are:
  • no or little vacuum to allow fuel flow;
  • vacuum controlled cut-off fuel valve faulty.
A workaround is to install a manual cut-off or bypass it entirely.

Incidentally, the 'revs like mad' is a result of slight overflow when fuel first flows to a starved/empty carb bowl.

Good luck and thank you for using FixYa.
