The products is solid and works well except for the c-clip which bent with almost no force.

Bin leider nicht ganz zufrieden. Das kleine Teil (Mitnehmer?), welches vom "Halbmondritzel" ist angetrieben wird, passt nicht 100%ig. Der kleine Bolzen ist ca 2 mm länger und packt nicht richtig in das Gegenstück. Startet man trotzdem mit sehr viel Kraft, ist das tierisch laut, weil der "Mitnehmer" I nicht richtig zurück geht und somit ständig über das Gegenstück rattert. Besser kann ich es nicht beschreiben.

Die Qualität ist sehr gut + der Einbau ging einfach. Der Motorroller startet nach dem ersten "kick" sofort an;immer wieder gerne.

Not exactly the same. You can use some existing parts and make it work. All I needed was to grease mine and I would've never needed to buy this. I read online diy blogs that were wrong. Mine was sticking due to gunk n no grease

Worked perfectly on my 139qmb engine. This kit did come with the o-ring and sleeve.

Terrible! Did not last 1 kick. The original has a full piece of steel surrounding the shaft, the weld is further up on the teeth than the original. It stripped out on the very first kick, as a matter of fact I could not get it to stop at the weld, it jumps right past it. Terrible quality control Very disappointed!Look at the pictures of my original, and the one they sell, the difference is obvious!Even the shaft is way to long, it sticks out too far from the case.I will never buy GooFit parts again.

Had a rough beginning but they worked with me to resolve all problems/misunderstandings highly recommended for anyone looking for parts. Best encounter on Amazon yet. Hands down! Thank you!

Great Gear working just fine. Mostly just needed the spring but I put all new parts back in on my SYM FIDDLE II.

Absolute garbage. (Goofit start gear) Purchased one, came with weld occlusion between two gear teeth, making it useless. I returned it and ordered a replacement... which came with _ANOTHER_ weld occlusion, this time bridging two teeth in another area of the same gear. _One_ junk part getting past a manufacturer's quality control? Maybe. That I get two, and both are defective? What are the odds. Statistically, I must conclude that the manufacture of this item is grossly substandard. I wouldn't waste my time trying this part from the same manufacturer again. If this _clearly visible_ production defect gets through QC, what hidden flaws may well remain hidden, to be revealed soon after installation. Far too much trouble to disassemble everything again. And here I am, with a partially dis-assembled scooter...Additionally: unless the seller (Goofit) has _just_ begun selling this item from a particular manufacturing lot, it is safe to assume that they _know_, by reason of a high return/complaints percentage, that the item is junk, yet they keep selling it. Though they may deserve the benefit of the doubt, I will avoid this seller.My strong recommendation: Don't Buy This Part!
