For the jets, you can solder the holes shut and then re-drill them to the correct size, saving the need to buy more, a common fix for people who went too far with making them over-sized... :)
Jets are cheap. Better to use fresh new ones. Jets are not just a hole through a little brass screw, but an actual nozzle, specifically shaped for creating an atomized fan of fuel. With a Bing jet for example, even using the wrong size flathead screwdriver to unscrew one, can damage correct flow.
There are now so called smoke free synthetic 2 stroke oils that were developed for Jet Skis and Snowmobiles. They also run at higher petrol to oil ratios. 50:1 say instead of 30:1. Amsoil do one which can be used 100:1.
Wooow...I had some of them, five exactly in the seventies! It was my first moped along with DKW Hummel, Victoria Vicky...some Zündapps, some Herkules...wonderful times!😍
I just use a standard piston stop, for finding TDC, Then always a timing light, for timing. I find it the fastest, least fiddly way to get timing on. Often when I have done timing however, the stator plate needs it's mounting screw slots lengthened, to accommodate 70cc, or other capacity, top ends. 😁
Hi, i have been trying to get someone to explain how to do the timing correctly on NSU Quickly's for about 8 years. Finally my saviour hopefully. Thanks for posting this video. Question 1, Where did you get that piston stop??. I have one but it does not have a screw to lock it like yours. I have taken my Quickly's to so many guys, who have either not wanted to or were not able to set the timing. There all in the shed, non runners. Question 2, Did you turn the stator plate slightly to get it closer to lining up correctly?. Question 3, I set the timing yesterday on a Quickly engine and it looks like the points start to open at 25mm before TDC and are fully open 0.3 at TDC. But the points are open for about another 40mm after TDC. Obviously when they are open fully at TDC, it takes time for them to close again. Is that correct or should I just check that the timing is lining up with a timing gun and forget everything else. thanks Tom Cahill, Cork, Ireland
I don't think i've experienced one basic moped that ran correctly without the airfilter. They're jetted with the resistance offered by the filter in mind. ..and yeah.. It sure does sound like it's running too lean, and getting hot fits with that problem.
I've adjusted ignition on quite a few mopeds, but never like that! Maybe I should start to do it your way, as I already have a timing gun! My advice would be to get an adjustable nozzle - just be careful! I tried the one from mopedspeed for bing carbs, and it was too large so it cracked that carb when I threaded it all the way in! (I know, I should have felt it, but I really thought it was just the o-ring on the nozzle binding up!)
@@lettuceman3848 the problem was actually not the length, but the fillet on the tip. The one from mopedspeed was more “square” compared to the original jet!
And a nice expansion chamber we did pulled better and sounded great.and mpg

Bad thing about that is that you rarely get it just right

Ive never seen that type of tdc tool before. Now I want one!
I learned something when working with mopeds. Dont test drive them downhill. Usually u have to push it back uphill, haha :D
😂👍🏼
But I live ON a hill as you know! Either I have to start the moped up hill or go downhill and push them back..... the struggle is real!
Hi , is the exhaust clear? I did not see any smoke on your test run, which is unsual for a two stroke, just a thought, haha. Many thanks from UK.

@@delukxyOh, that's very interesting. I have a 2 stroke car, so I will have to look into that. 👍
@@neilfoster814Which Car?
Trabant 601?
I have one built 1965
Its all new! But running on some special low smoke gas on this one (all I had)

I had similar problem on my Quickly. Cured by new barrel and piston. Two strokes need plenty of compression. Cheers
Damn…saw the NSU tag and was hoping it was a ro80

I had one in about'56. It was a great little ride and reliable. And just like yours.

Have you got a set of jet drills if so fill the jet with solder and redrill the correct size.
Where did you find a piston stopper like that
That was a pretty cool way to set the timing.

Tried both with and without to see the difference... I always struggle to figure out if its lean or rich to begin with (unless it 4 strokes)

I got the one from Mopedspeed and have the same problem! did not crack the carb though.... (lucky)
@@SeasideGarage too bad! Happy you didn’t damage anything!
Yea the old bing carburetors had two different jet lengths one 26 and one 31 if im not wrong gotta measure them!

Did you ever get it to run correct?
Not yet! Got compression issues...! :)
O dear. We're the rings seated on the tabs in the piston when you put it into the barrell?
I really liked the screw in Top Dead Centre finder, better than a dowel and a marker pen!
Great 👍
