What is this part? (Puch Maxi S)

Henrik Andersen /

I recently got hold of an old Puch Maxi S, which i intend to restore as good as i can.

I need some help finding out what this part is and does. And where i can get hold of a new one, since this one is broken.

It is located on the cylinder head.

Here is a picture:

Looks like a decompressor valve of some sort

Never seen one on a puch though

Just put a diffrent stock head on and be done.

The de-comp came on alot of older Euro models and is hard to find in the U.S.

So its just to make the moped easier to start?

Re: What is this part? (Puch Maxi S)

yes. that's all....but a leaking one can be bad news. most people just change to a regular head or a hi-comp head....

Overpriced Parts /

Not needed at all

Big source of problems

Re: What is this part? (Puch Maxi S)

cheapest solution would be to find a stock puch head without decomp valve.

if you're looking to upgrade however treats has a nice higher compression head here for $30 US. (I realize you are overseas and that shipping costs/time are higher than they are stateside).
