Wow, not one of you has started with the basics!! Naughty naughty When was the last time you checked your valve/tappet gaps? or did a service??
could it be youve just reknewed the he s n stuff n it needs re tuning etc assuming you dont have air leak ?
did you try pull push? Maybe you're allowing it to back on to you, try pull push first then report back. Here, i've done a video for you
you're on mine because of the length of your fecking signature. I've seen Professors with fewer letters after their name
It came to me in the middle of the night (about the only thing that did), how about a sticking valve when shes cold? I've seen this on aircraft engines. Tony
Malc you shouldent have moved so far away from me then i would be able to just pop round and help you
Take the rocker covers off lift back the valve stem seals and spray plus gas down the stems See if it does the same the next morning???
