Well I went over there and pulled the head off and he turned the adjuster soo Mutch that the exhaust valve was open a 1/8 of an inch and the gap on the compression rings were on top of one another so after 2 hours of tinkering with it it started

good save man !
I knew it had to be timing or a valve hanging open, even burnt up it shoulda shown some compression.

Well it's gotanother problem now it wants to run away at idle after I left they finished putting the snorkel on and the plastic and stuff like that and it will sit there and idle then it just starts idling up and starts revving really high just sitting there soon as he sends me a video of it doing it I'll post it up but I have no clue about it

Maybe an over lean idle setting or an air leak.

I have had this issue carbs on those have to be perfectly cleaned

 

[mud runner]

I know it has gas and we're gonna put the carb off of my Kodak and intake boot and put it on his and see if it makes a diffrence

 

[harley1-5]

if the choke isn't just right itll do that

 

[mud runner]

Well when I left it ran fine idled perfectly but after they put the plastic on and the snorkel it started running like crap

 

[harley1-5]

maybe they knocked something loose putting on plastic?

 

[mud runner]

Ya I don't know I'm gonna look at it tomorrow

 

[harley1-5]

let us know

 

[mud runner]

He sent me a video of it running but photobucket won't let me upload it

 

[mud runner]

He fixed It they had the throttle cable hung up and was causing it to stay wide open
