Hi all,



I just picked up a 78 Xr75 and cannot get it to start. I fired slightly a couple of times, and I though it was going to run. But no. I gave it fresh fuel, cleaned out the carby, it has really good spark, and the compression feels good too.



Any ideas?

Check the cam chain tension and cam timing. Notorious jumpers.
