Has this been a gradual happening or did it all come at once?


id="quote">
id="quote">the valve was stuck pretty bad . took the head off and lightly tapped it down spent the next two hours working it untell it stopped sticking . but I did get a bunch of marvel oil and liquid wrench in the muffler . that has pretty much burnt off I have started it up more than a dozen timessorry I didnt answer the question sm00 It did not run when I got it . it looks like someone has been into the engine though so the answer would be " all at once ":D

Sometimes they get that way from sitting or just from aged/bad gas varnish. I had one that took forever to find because it was intake and would only stick after 10 mins or more of running, and sticking was only visible by dropping gas on the valve in 'closed' position. Sometimes the best thing is to take it out and polish the stems.

I keep running it ( with marvel in the gas ) and it has stopped thunking and stopped smoking and will run for two or three minutes and then start to die and then smooth out for a bit and then die its slowly getting better but I will probably pull the valve at some point

How is the clearance? It might be on the border of too tight when hot.
