Hi, I have owned this machine about 3 years and it's a nice smaller machine. I have a problem now with the 21 HP Intek single. When I got on it to change the blades yesterday, it cranked over like the battery was weak, or it had unusually high compression. I started it by jumping it and it ran smoothly, but with reduced speed and power. When I stopped it would not crank over as before.
Reading on forums, I learned this engine can have problems with the intake rocker arm stud getting loose and backing out. I looked and, sure enough, mine was badly loose. I tightened it and reset the valves, but this did not improve the cranking and I could not get it to crank over and start even jumping it. The engine will turn by hand and it seems not too tight except in one position, like really high compression. Any ideas or experiences? I may just order a new engine: about $550 I think. Is there a better replacement engine? Kawasaki?
