Carb issues, Zeda 100

[ImpulseRocket]

If you want something like the phantom for somewhat cheap do a saw hybrid. I recommend them all the time for people who want a phantom without the phantom prices and extreme rigidity. It takes some effort to put together but if you’re willing to go through the effort, it’s totally worth it in the end. In fact I believe you can skip one of the hardest steps with these builds by using an ms380 52mm cylinder.

But it does have its draw backs. For example most saw hybrids have a hard time with stroke match. For example an ms460, the one I have, doesn’t like 40mm cranks but it does like 38mm. I have a 40mm in mine but it required some extra modification to the cylinder to get it to run right. I don’t believe the ms380 had the 40mm crank issue. Also there’s the issue with the wrist pin size being too big for most newer MB engines so if you got lucky and got a 12mm rod then it would make things a lot easier.

most people don't have the skills set or confidence to do a saw build. It's more involved to get right than people give it credit for, and to do one properly with a good quality cylinder is going to cost more than a Phantom, and the Phantom is basically an MS460 saw build, but with all the work done for you.

Just wanted to fill everyone in with some new details. I decided to put my ebay engine back on the frame with the 36t sprocket. It was as slow as dirt!!! I could sprint faster than that thing, it took about 20 seconds to get top speed on flat. Dont even get me started on the hills. It did have some good top speed once it got up in the RPMs but it was so slow it was almost a hazard on the streets near me. This could also be the fact that i broke the piston ring and put a 49mm ring back in it when its supposed to have a 50mm, not sure but it was really slow. The old and new ring looked identical visibly when installed on the piston.


The Zeda was a million times better in terms of acceleration. I threw it back on the frame and decided it was good enough for me until my phantom comes. (the phantom is back in stock on bicycle-engines, hope my order is fulfilled soon through motoredlife)

As long as you are easy on the throttle, the Zeda way outperforms a stock motor. Anything over half throttle is useless and does nothing and will bog it hard. Also i forget who recommended the chainsaw plug but turns out that was also hurting my performance. The end of that plug is so shallow it wont even clear the bottom part of the head of the Zeda! I put the stock plug in and it actually ran a lot better.

The rings might look the same visually but your ring gap is going to be bigger meaning you’ll have less compression.

It was @DAMIEN1307!!!!
...if it wasn't me that is... uh-oh... anyways, whoever it was, I'm glad you found that out!

Wrong...@ImpulseRocket is the guy using the saw plugs...I use the NGK-BR8HS plug on both my Phantoms.

yea i was thinking the same thing, the ebay motor pistons have much smaller ring slits, at least compared to my zeta piston. The zeta uses a 50mmx2mm. and the ebay one needs a 1.5mm! Even with the 1.5 it was super tight compared to the bottom stock ring.

That was probably why it was so slow tbh

I've been correcting the spelling but now I'm not...lol...lol.

It is ZEDA, not ZETA, your gonna make folks think there is a new brand out there...lol.

DUH! you're supposed to check the ring in the bore for a match, not on the piston. That way you can measure the end gap and then decide on using it. I mean, if its got a 1 mm gap, why even bother?

I run both styles of plug. I've never noticed a difference between the two as long as they are both genuine plugs. The only difference between them is the length of the threading and size of the ceramic body -made a bit smaller because they go on small engines with shrouds. I would love to see you make the claim that the saw plug hurts performance after you get this engine to even run properly. Until then you are just throwing accusations at parts with little to no data to back it up. You could have simply received a bad plug, or a cheap copy chinese plug sold as a genuine NGK. It happens a lot more than you think.
