I let one go a few years back and regretted it this one gonna stay
Here

I'd keep that one forever. Then my kids could throw in the dumpster when I croak. Kind of makes one cringe a bit.

 

[PogoInTheWoods]

Take it with ya.

The IP of the 800 shows either a decomp or a bolt that holds the bracket for the top of that goofy screen muffler.Has to be one or the other because there's only one hole Decomp # 215673 which I would say is the same as the 805 which also comes out the side . I would assume then it is the larger thread size like the 805

Closest I came was a 250 and it says a" Package" of 25 not the actual count .

Although I could not find the IPL on the D-44 in looking at other IPLs it shows 24 needles on every other reed valve engines .On some of the kart forums they mentioned Terry Ives has them .

24 on the needle bearings. The Kart guys used to leave one or two out to free it up a bit, just make sure you don't leave any loose running around it the crankcase.

I found the rest of them. They were stuck to the magnet on the parts tray got them back in today. Just trying to figure out the trigger assembly. Think i got it figured out. If anyone has a teardown of it they could share i would appreciate it. Thanks again.

I can't help you out .I've got a super 44A which is an 87 cc and a power house .All I've ever done was a carb rebuild and bypassing the air vane governor .Pretty impressive for circa 1959 -60 .I was 11 or 12 .

That was good with the parts tray. I need to do that when working on them rollers as have lost a few myself in past.

Be careful using magnets on the rollers Kevin. They can pick up some magnetism and hold metal filings. I dont know where the metal comes from but it seems a magnet always finds filings.

 

[Gizzard]

Good point @Steve. I had not used a magnetic tray before. It just got me to thinking (I guess a bad thing )...I've lost a few rollers before...maybe a few brains over the years too.

 

[heimannm]

The roller should be hard enough that they are not easily magnetized. If you only have them exposed for a short time it should not be an issue. Even if they do pick up a bit, the shock they receive when the engine is running should knock it out in short order anyway.
