Kawasaki mule pro mx 2020

Hi we have a mule with a kaf700 engine. It was struggling to start and run so remove fuel tank and fitted new fuel pump due the amount of dirt in the tank and had the injector repaired. It was slightly better but not right. We tried a different throttle body and that didn’t help much. We compression tested it and cold and hot was around 70 psi . We’ve removed the head and found the valves not sealing correctly . We’ve sorted that and it’s around 130 psi now . When the spark plugs fitted now it struggles to turn over. Before it was fouling the spark plug aswell.  I’m now thinking that there’s been an issue with the decompression on the cam shaft . Has anyone had similar issues ?? Thanks

Had a John deer,that went to the paces like you have got compression up to par then wouldn't turn over fast enough to crank. Choked starter was working but week,put new starter on and fired right up.  Hope you get it going

Hi just thought I’d update you. Put a new starter motor on and starter clutch and it cranked over. So that solved that problem still ram roughy and traced that back to one way valve on fuel tank being fitted wrong way now runs perfect cheers
