If we all get one guess...

Mine is the condenser is bad.

could be a rusty gas tank mixed with dirty carb or an air leak. The bogging shows signs of dirty carb or air leak while the dying engine seems like crap is getting in your carb- I.E. dirty/ rusty gas tank-

1st. Clean the carb very well --then reinstall and while it is idling spray carb cleaner at various points around the carb and intake- if it kills the engine you have an air leak. If so, use RTV gasket red sealer from Napa or auto zone and seal up where it leaks.

Also, for the tank I would install in inline fuel filter from auto zone- costs 2.50. it is easy as pie to install and will prevent most light rust/dirt from your tank from clogging your main jet in the carb.

If it still bogs you most likely are running a too large main jet (brass screw in carb) and you need to down jet. its a dellort 14.12 on a V1 right? good news is 1977mopeds has all ranges of dellorto jets for you. Though my bet is on 1 and 2.

Good luck- i dont think it is the condenser personally. nor a soft sieze. 1 and 2 are the most common issues.

Threw some Sachs Eagle II shocks on my Snark. Had to drill the bushings out to fit the bolts. With my weight I was bottoming the stock ones out! Rides much nicer now.

not the condenser... she can idle forever.

Quote: "Remove all carbon. Most peds get carbon on the head and piston. If black/dark brown, use steel wool and remove it until you can see the original color."

If the carb clean up / possible replacement does not solve the issue... this step will be in order.

What might the torque spec be for putting the head back on ?

did you test for an air leak yet?

Next time it does it pull the fuel tank cap off. The vent hole might be plugged.

Here is the low down...

I pulled the fuel line, checked the petcock vavle for debris... Good

Inline Fuel Filter is clean and new... Good

Checked behind the banjo fitting and that screen was clear of debirs... Good

Pulled cover and retaining ring off of air filter... Good Filter

Took her for a spin after making final adjustments to the throttle.. and she rode like a rock star!!!

Only thing left to to is get a new throttle cable, possibly a spark plug change, and check the throttle/grip assembly.

I suspect the throttle cable/grip for the poor idle.. it used to idle and now it just dies... but I can tell that the RPMs are not the same as before after making the throttle adjustments. plus the damn grip mechanism is janky and weird.

thanks for the help!!

wd40 the throttle grip insides- that might help.

The air filter is attached to the carb air intake .

An inline fuel filter may be in the fuel hose from the tank to the carb .

If there is none , it would be a good idea to add one . It should be a paper filter , good to at least 60 micron .
