i was out checking my valves/springs and i think i may have a problem.. but it seems kinda like a too soft spring.. not a stuck valve.. dammit, come home!

 

Which one? A weak spring can also do it. If excessively weak it can allow the valve to stay open longer by not allowing the rocker to follow the cam lobe, it would get worse with rpms. Hence the compression during cranking speeds. Since the valve is lagging the cam (not following) Duh! it would allow the mixture to escape. Keep us posted. Sorry I wasn't on.

BTW I or E valve?

 

#4 exhaust. When i tap it with the hammer is just seems... "soft".. more springy as others.

What you say makes sense.. but wouldnt it make a backfire noise or anything out the pipe?

 

i talked with my pa about it.. he agreed.. and since its the exhaust, it would be like giving it a LOT of overlap on that cyl. Rob it of tons of power he says. which fits what I thought all along... the cyl IS working, just not very hard.

Hmm... how did I get a county worker in there?

 

not yet..

 

yup, i have. I will change this spring then put it all together and try again.
