i re powered my 300 with a vanguard 18hp but i am having pto issues it burned the original up may have not set up air gap right. bought new clutch and set air gap correct. pto runs for about 30 seconds before it stops and stalls the tractor . any ideas ? thanks Dale
I had the same problem when I replaced the 341 with a 21 hp Vanguard. You need to use a spacer to mimic the step on the kohler shaft. I used a thick washer.
