Installed new clutch, engine shakes upon acceleration and slower to take off.
I have a yamaha g16a. I recently installed a new comet clutch (bestauto from amazon) and now i'm noticing the golf cart shakes a little bit upon acceleration and doesn't go as fast as it used to.
I think i have the starter generator belt tightened to about 3-5 mm of play. When i get up to higher speeds the golf cart runs fine, just takes a lot longer to get there. I think the carb may be dirty, and it started running much better when I put some sea foam in it, but still has the issue I listed above. I did not grease the clutch as some reviewers said it was a dry clutch, and there are no grease fittings on it. I also noticed a thread coming out of the starter generator belt. Could that be it? Any ideas? Thanks |

Re: Installed new clutch, engine shakes upon acceleration and slower to take off.
Update - I have noticed the cart runs great in reverse. A few forums searches tells me that it could possibly and most likely be the crank shaft seals. They seemed to work fine with the other clutch, but not so much with this one.

Shouldn't be crank seals. If you installed a new drive belt it could be that the new belt is "sticky". Sometimes brand new drive belts need to wear in a bit before they get smoother.

Re: Installed new clutch, engine shakes upon acceleration and slower to take off.
I tried it with the old belt and the new. Both seem to produce the same symptoms. The old belt looks pretty worn down compared to the new. I wonder if both of those situations could produce the same results. It seemed to drive much better before I did all of this though... I have a mechanic coming out today.

Did you install the clutch with an impact?

Not saying this is it but....
I know Comet clutches are being knocked off in China. Is this a genuine Comet? Is the seller a Comet dealer? Did the clutch come with literature? If it's a China knockoff it might not be operating correctly. The $80-$100 clutches online are usually not genuine, they are fakes or copies. If it's a genuine Comet, I'd be calling their tech department for advice. It could possibly be defective. A genuine Comet clutch will run $200-$300 or more. |

Looks like a knockoff of a Yamaha clutch... Wonder what it looks like under the cover... |
