That is a shame and should not be, but would explain why they used a stronger starter/generator mount. When I heard that I was wondering why the heck they did that. I was told because the 3pg makes more power, but that makes no sense, I mean, you could have a motor make 100HP and it would not need a stronger mount, maybe a little stronger if you had a lot of extra compression, but.....

speaking of vibration, i should address it while most of the cart is dismantled.

update, had to have the starter/generator rebuilt. the nightmare of the bolt removal and found a crack in motor cradle. always something haha.
