My PP475 has a slab sided BB372 piston that is almost identical to the oem windowed piston in it and I swear it feels stronger then stock.

Even though I am not  switching P's back to back to find out. I am happy with it big time.

Well I had the luxury of two saws, so I did one each way. The one with the windowed 262XP piston is at 155PSI compression, not started yet, so once it breaks in compression should go up. The one with the 365SP is at about 168-170 PSI. Get them both running later this week, so we will see.

It wouldnt matter to me which runs better . Because the PP475 pistons are NLA and I was looking for a donor piston. 

I passed my NOS 475 p onto Roger because I new he was more of a collector. Me as long as the saw runs good I am happy and found a piston easy to get for the 475 saws.

The 064 pistons work in these too.  If you must have windows. Little more pin to crown height too.  Just need to open between the pins some like I did the 066 piston in the 505.

UPDATE:  tried another used carb from ebay and once again same thing on either saw. idles fine sounds good on the high end and when you let off the trigger dies so i now have 1 out of 4 zama c1q dm14a's that work. did a little more research and found elswhere that the little valves inside these carbs are reffered to as the nozzle assembly check valve and are zama # A007222 for this carb. I ordered some and first place cancelled my order stating that zama no longer made them????? found another place and they have not cancelled my order yet so maybe they had them in stock. where I read about  this also had an ingenious method of removing/replacing them from the carb using a drill press with a bit upside down/flat end down. tried it on my original carb and out it came with a little pressure. as soon as i get the new ones in I will get it all back together and post the results.

No real problems with the 5100 carbs either. A few that ended up lean after break in and had to replace under warranty because of the epoxy. new carb through Dolmar is $105 or a new one straight from Zama is only $51. Only difference between them is the one from Zama doesn't not have the plastic clip for the throttle cable on it. you have to reuse your old one.

Am having no luck in aquiring these check valves........How do I order parts directly from zama? I am just a Joe Schmoe not a dealer and it seems you have to be a dealer.......their site sends you to distributors but doesn't seem to be any luck there either....I am at the point where I am ready to just get a whole new carb but really don't want to pay $100 for what zama says is $51.... any suggestions? I would much rather just pay the $4/check valve for a few of them but it seems zama is not supplying them any more...been rejected by TEW and Jack's se which were the only places I found carrying them through google......

Try this guy on e-Bay! Just send him a note, his name is Carl Neilson and he is a Zama dealer. Great guy and if you have the part number he can probably get it for you.

Fairlane78: I just sent Carl the following message for you however it is Wednesday and that is Carl's golf morning so may not hear back until later in the day.

Carl, I need some parts for a zama c1q dm14a, referred to as nozzle assembly check valve and are zama # A007222

Was wondering if perhaps you could get them, I need 6!

No joy! Here is Carl's response, sorry.

Hi. The part number is correct, but my Zama distributor doesn't list it. I checked for availability from other dealers and they all say NLA (no longer available). Sorry. Thanks for asking, Carl.

Sent him a response asking if the carb is available and the price!
