    • I’ve lost $3500 to a scam when I was 13.  Same deal [email protected] came across.  So yes, if it’s too good to be true, than it isn’t.  Never ever send any money for any reason thru money gram or Walmart transfer or by taking pictures of eBay gift card and sending them to anyone.  Always buy in person.  No handshake, no deal is my rule.
    • Thanks for the replies, i'll be checking that later forgot to ad that it runs really well for a couple of seconds before the fuel runs out/empties from the carb. 
    • 4  things  could  cause that problem.   Timing slipped   so  the  intake  valve   is  still partially open  when  cylinder fires ,  Intake  valve  is sticking slightly  open, rocker  arm   is too tight  and holsding  valve slightly  open  and finally,  a burnt  intake valve valve allowing  combustion gasses  to  blow back. Most  likely  is a timing slip  or  valve  lash on the  intake valve is too tight .  
    • So it took a bit longer before they were delivering it back to me. Their mechanic first wanted to deliver it to me in parts but obviously I would not except that.  Finally got it delivered this morning, after my work in the forest I took it to the workshop to start the repair and see what they actually did. To my biggest surprise they haven't touched the fuel pump at all. A thick layer of clay and mud gave that away. How can you start diagnosing a fuel pressure related issue without checking the item that provides the pressure. Shoot me, I have no idea what he has been looking for.  Took the fuel pump out and "popped" the screen which is in the middle section of the pump. Cleaned it all out with compressed air and brake cleaner. Put it back together and all problems were solved. It has got its full power back and runs perfectly fine.  Two hours of work and that was it. Has probably been one of the easiest repairs I have ever done.  Hopefully my tyres come in next week and after they arrived I will give an update to the shop.  On the photo you can see how the machine was standing in their workshop. If anyone has a clue what their mechanic was looking for, please share. Second photo taken just a few minutes ago while out driving.  Cheers all!
    • Need to do a leakdown test on engine. Also need to pull valve cover and check for a sticking valve.
