This 066 Grenaded........What The Hell Happened???????

[Trx250r180]

was there any fuel in the tank when you got it ? dump it on the bench and when it dries should leave an oil spot if it has mix in it ?

disregard ,i see above post now

 

[HuskStihl]

Bearings locked up(no oil), then disintegrated, followed by pieces of the race getting sucked up the transfer port into the combustion chamber?

Needed ceramic bearings. Can run RP at 200:1 with ceramic bearings

 

[moody]

Bingo......

It had oil, just not enough for the pressure it was under.



No scoring on the piston.

At 80:1 he may as weall gassed it lol

 

[struggle]

same here disregard my comment. I now see the rod picture as well. Does it have two ports on the exhaust though?

amsoil 100 to 1 opcorn:

i run 32 to 1 like you had me do ,when i tune by ear in the cut ,i adjust rich till it burbles then cleans out in the cut ,every time i inspect my piston ,it is slick in oil ,and oil in the muffler some ,i see no oil here like in my saws ,too lean on oil will kill the bearings in i hi-po saw

I need to add a disclaimer to my sig.......

Any saw not used with H1R @ 32:1 will not be covered by Mastermind Worksaws.

Ceramic bearings won't last under the loads these engines see. Not according to guys that know far more than I do.

No, just one big one.

You could run any dino oil @ 32:1 and not tear up any bearings.

Randy I tried to like your comment and I ended up making it funny iPad not fat finger friendly

That was a joke based on that eBay guy who sells ported saws with ceramic bearings. I was trying to cover up for my total lack of 2-stroke understanding. I think I just made it worse. FWIW I listened...

any problems with the h1r seperating from the fuel in cold weather ? i had dirt bike oils in the past that would ,i think it was 927 maxima

The suspense is killing me. ..

Idk, doesn't get cold here. Ohhh, I bet you were asking somebody who would actually know.......

Me too! There was something about oil and bearings, but honestly it was all over my head!

too lean an oil mixture broked the 066

The saw was used with Amsoil Saber @ 80:1

The lack of oil killed the crankshaft.

Pieces of the bearing cage from the big end of the rod bearing when up thru the transfer ports and wreaked the piston......

Just curious Randy, do you recommend 32:1 for stock saws too? Or better phrased, do you recommend 32:1 in saws that call for 50:1?

I've come to accept 50:1. Now you've got me wondering if its the best thing for my trimmers, blowers, etc. I'm thinking its all gonna get 40:1 anyway.

 

[eiklj]

So what do I win?

 

[HD2010]

Amsoil Saber @ 80:1

Didn't that long to kill it either.

How many tanks of fuel Troy?????

I'm guessing a dozen tanks. I have now changed mixture 32:1 as reccomended by Randy.

I run Belray H1R at 32:1 in every two stroke engine I own. The 50:1 bull **** is EPA crap.

I didn't think it went that long. It was still pretty clean. You must run a good sharp chain Troy.

I'll supply a good crank, or a different bottom end, and the labor. You pay for the piston and gaskets. How's that sound?

I'm serious about having happy customers.
