If you've got mixed oils doesn't that indicate a gasket might be blown, too? Loss of compression, then?
So it turned out the head gasket was blown. I replaced that, the intake gasket, and the piston rings (after I broke them both).Still no dice.Took it to Austin Mopeds finally. A sizable chunk of change later it's running like a dream. They just needed to adjust the timing and clean the points. The work I had done was good. The timing was just way off (probably to accommodate everything else be
So, if I test the compression at the spark plug hole, what's a good reading?
Thanks! And, weren't you the guy that had the gas cover, too? I tried to email you. Did you get it?
Where do I start looking for low compression? Which seals should I check (and how)?
Bought this thing a month ago. Ran fine. After the second tank of gas I added, it started missing and dying a lot, and was harder and harder to start. Replaced plug, seemed to work for the 10 minutes I tried it. Next day rode a half mile just fine, but next time I went to start it, no good. Today I did all the work above.Okay, I:1. Drained the tank2. Opened up the carb and cleaned out the float bo
Oh, and the gas that came out looked pretty okay.I also removed the air filter. It was the ORIGINAL filter! It was pretty nasty. I'm picking up a new one this week, but a local mechanic told me it would be fine to run without it.
Okay, I:1. Drained the tank2. Opened up the carb and cleaned out the float bowl, float, and jet, filter, and any hole I had access to.3. Replaced the fuel line and filter.4. Cleaned out the elbow pipe coming off the petcock.5. Cleaned the spark plug (did have some debris/oil).6. Carefully mixed 2 gallons of new gas and oil in a can and filled her up.7. Ran it on kick stand for a few minutes until
No dice. At lunch time, it was really hard to start, and wouldn't stay running very long.Fuel filter next?
Finally got a chance to work on it. Replaced the spark plug and it started right up. Didn't get to ride it until today. It was still missing pretty badly, and dying a lot, so I put a bit more gas in (to try to balance out the mix), and shook the tank. Rode it for about 10 minutes (with lots of stop/start), and it was running much better, though still occasionally dying/missing.Can't seem
Anybody have a part number on that filter?
I bought an 8-ounce bottle and eye-balled 5 ounces of it. The chart on the bottle said 5 ounces per 2 gallon tank (I might be wrong on the exact numbers - might have been 6 of 8 or whatever).
This is the ignition armiture. It's covered in what looks like fresh oil. Is that bad?
Got a couple pictures that might be interesting.This one is of the bulb right above the primer button. It looks like there's a lot of oil in there to me. If you swish it around it sticks to the walls of that bulb. It looked like this this morning. Yesterday afternoon it just looked like there was gas in there. Maybe this is just from settling.
1979 Prima G3 505/1ASo yesterday while riding to work it sputtered a few times toward the end of the trip. It felt like it was misfiring. It kept running, but it felt like in a split-second the engine would die and start up again, sometimes several times in 15 seconds. Only did this for the last 5 minutes of the trip.At lunch it was pretty hard to start, and only did the misfiring thing a couple t
Oh yeah, and I have a complete set of gaskets (minus the ones I already put in).And the asking price is $1500.

Haha, I guess those are actually screws and not grommets.
You can see here what I'm talking about. I have the plug, shown, but not the cap that would cover this whole area (including the inlet, also shown).
Anybody know where I can get a cover for the gas cap/overflow inlet area on top of a Prima G3 tank? There's a strip of rubber grommeted to the top of the tank that looks like it held some kind of cover. Right now, in its absence, there's nothing to prevent rain water from running down the overflow inlet.
Corazzo. Heh. If you want a jacket that cost as much as your moped, maybe. Thanks for the tip, but a bit rich for my blood.
Good call. There's a surplus store right around the corner. I'll check there. Thanks!
I should probably mention that I'm in Austin, where it's going to be 95 soon.I'm wondering if you guys wear jackets when it's warm as well, for the protection (the way you do on a motorcycle).
What do you guys recommend for a jacket? It gets cold without one, but considering the low speeds I think the kind of stuff you would wear on a motorcycle might be overkill?
Thanks. Yeah, I realized that I kinda duplicated a few different threads by starting this one. People are saying the 1A and 1D manuals would have been so similar that there might not have been a 1D.What I don't get is that the wiki page says the 1D doesn't have a needle. That seems like a big difference.And this bike is marked 505/1D, but the previous owner described what I think was a n
Not eve for the turn signals/brake lights?
You mean this one:http://www.mopedriders.org/html/manuals/general/generalsm.pdfThat's for the 505/1A. I have the 1D. Does it matter?I'm trying to find out what battery I need, for starters. That manual doesn't mention a battery.
