MOPED ARMY

Flood style choke like a Gunter...or Sachs

Make sure to use some thread lock on those reed screws. Ha!

It makes about as much sense as your reeds too tight theory.

You’re likely pig rich on the bottom so your flooding and that’s why it doesn’t start.

The only reason the reeds could be an issue is if they aren’t closing all the way

In your mind I’m sure you’re right

I think you have tunnel vision.

You convince yourself that something in particular is wrong then focus on that. It’s a very poor way of problem solving. It’s like focusing on debris in the road in front of you then you hit it cuz you were focused on that rather than evasive maneuvers.

There are so many other things that could cause poor pull starting. Hanging up starter shoes or clutch or one way bearing, a short in your plug cap or wire, any resistance to a smooth spin will stop pull starting from happening.

First take off the belt and clutch bell and clutch.

Then pull start.

That’s the way to figure out a problem systematically. Eliminate variables.

I agree with the too rich idle jet on the carb. Especially if it will start at WOT. What jet do you have in it? And if the answer is "I dont know" then it would be a really good idea to find out.

Also an airleak cam make it impossible to start and idle properly and will only start when there is enough fuel to compensate for the added air from the leak.

How long have you been at mopeds now? At least a smattering of years.

Your reeds should not overhand like that. High likelihood they are catching on the cases trying to clack open. Either open the holes in the top of the reeds, or trim the ends off.

Also, clean up that reed block. I can see parts where the rubber lip is all goobered up.

If your reeds are stuck closed, it's because you goofed

Okay so the reeds were able to be opened when I peeled the Reed block off the intake and I could take a screwdriver from above and gently press both both of them and after I filed them they did open easier they seem to be tiny bit easier to open but my test was pushing a thin screwdriver from the top down and seeing how flexible the reeds were and if anything was catching I don't know they seem to be slightly easier to open nevertheless I put the whole thing back together remember I'd never taken the spark plug out when I pull the frame up a few inches using a a-framed ladder above it into straps so then I put it all down after it's all bolted up the only for like things I took off for the intake bulbs torque it down pulled it a bunch of times nada and my friend Jerry was here as a witness I said look I'll pull out the spark plug and then I'll put it back in and then we'll see so I did that started on the first Pull. So basically I think that if I had a decomp on this head where I can get some oxygen in there between attempts instead of just sucking preferentially through the exhaust Port which is clearly what is happening the thing would start I don't even know if a different carburetor would make a difference at this point. I think what's really needed is either be dumb enough to take your spark plug out every time you want to start the damn thing with this pull start or get an appropriate large head that cools it appropriately such as the Derby modified with the decomp not with the welded decomp. And obviously the biggest mistake in this build was not using a PA 50 2 crank just my buddy was positive that that crank was beautiful and it is a really nice PA 51 crank I don't think it had anyware on it at all but now unless someone can instruct me on how to modify the the bearings so that I can use a one-way bearing on a pa50 1 set up I would have to break the whole motor down and rebuild it which really sounds horrible considering it's a beautifully built motor.dillon if you want to make me a derby head proper studs placement for a Hobbit that has a decomp and you've got some time I'll be in New York from the 17th through the 22nd and I can pick it up at your shop and visiting my daughter in weehawken. Once I get this thing started it runs beautifully.

So I'm uploading a few short videos of it running to youtube.

Jbot thanks for the encouragement !

So it's hard to do this with my phone but at least you can hear it running.

Dylan I think you're right there must be some sort of microscopic air leak that is blatantly obvious now that I've got this pull start and you know that rubber is what 30 years old so maybe I you know I as I play around with it more I'll put a little permatex or something you know I got some stuff that I think add to the ceiling quality of a 30-year-old oh and by the way like I've had that that everything else is really kind of perfect on this as I recall before I I went for these hot or hits because I just couldn't keep the temps down and hot hot weather if you open it up on this the way this bike runs it it runs in the 40s so I wanted it I wanted a solution and I'm almost going to get there real soon because the temps seem to be pretty good when I get it going but that's what I want to just solve this one problem and I think I'll consider some more empiric intake therapy so thanks. I just think that the short pole length of the pull start has unmasked some defect that is likely going to get worse and once I get it ironed out how to get the start correctly even if it requires a new carburetor I would just pick up a phdg stick it on this song on top of the deal Reed so that's easy but I just want to see if I could get this to do it just for the why not is it not working.

I pulled over well mountain biking to just add a few things I'm doing the terrible voice over and apologize anyway I couldn't do it otherwise. So I think I'm going to take a look at what Dillon suggested around that intake because perhaps when I leak tested it I did it below the reads I'm not sure as I recall to tell you the truth. it's been a long time. So I'll start there. Or just order a smaller phbg and start from there. I think they are on sale but it's a it's the thing I just

would rather fix before I put further changes. My engine has spoken to me and reassures me that her heart is young and with love and vigor. So I'll nibble at the edges

I feel like your biggest problem with the reeds not opening in that picture is that there seems to a large orange thumb holding them closed. Just clean that thumb off of them and they should open a lot easier.

...easy access. I'm gonna put the oem reed on for shit and giggles.
