At first glance I thought that was a Ford head.

See you know what I mean. At least Husky was smart enough to not put the coil on top of the plug.

 

[Mkinslow]

Yep. Mine is a 98 f150. So I don’t have to worry about launching plugs or breaking them off

It's a friend of my daughters.....been worked on by a bunch of kids. Now they can't get it to start. LOL
I told him to bring it over and I'll help him out.
I have no idea what I'm getting myself into. Until I really get I to it.

Check compression, if low it's most likely tight intake valves... A dirty or missing air filter the likely culprit...

Nothing real difficult there. Swingarm pivot bolt can be a royal PITA if it hasn't been maintained. Motors are pretty much bulletproof.

Pretty sure that “gas” is about 20 years old

I can smell that from here.

It barely even smelled. Seriously. It was so old it literally had almost no scent and was the consistency of maple syrup. Majority of it cleaned up with some carb cleaner.

I can’t wait to get my dad’s 026. He sent me a pic of the original sales receipt when he bought it in Sept 1992. I want to make it look like that again

What was the price in it new back in 92?

 

[Backtroller]

12/99, my 026pro with an 18” .325 was $439.95

 

[Cut4fun]

Much better. Drilled the pin out of the epa stop in the H side metal shroud. Was making it to lean and hitting rev limiter on the coil. Prefer my saws tuned fatter then their pinned epa stop allowed.

Ta-da......

Best thing I got right now

My dad is checking one of his machines, starts, idles, takes high idle, but is low on power - powered by a Sachs Stamo 96 2-stroke engine, 1cylinder, 90 cc.
Cast iron cylinder, aluminum cylinder head, no gasket, no signs of leakage, closed port fed.

I told him he need new piston rings, he wants to reassemble the engine as is.

Lots of blow by.


The cylinder bore looks impeccable, the smearing is how my dad checked for ring wear.
He smeared grease into the bore and rotated the crank so the piston goes once up and down - shows where the rings touch the bore and where they don't.


Now, I have a question.
Given that the cylinder is iron not aluminum, can I still go ahead and place regular Caber piston rings in this engine?
I came up with 52mmx2.0mm and the Greek on eBay has these listed.
Do I have to pay attention to anything else than ring diameter and width?

Any help, opinions and suggestions are appreciated, thank You!
