Bedford,

Thanks. I’m starting to read through all the previous posts now.

What are you guys measuring on the new cylinders?

You won't have the tools unless you are Machinist. it's hard to measure a two-cycle cylinder Because of the ports. But you can set it on a flat surface like glass and see if it rocks. And you could measure squish, which generally is the space between the piston and the top of the cylinder with solder. And you could look at ring gap, space between tips of rings.

I have a website with lots of info on the kits and some assembly videos.

I’m not a machinist, but I bought a machinist’s toolbox.... I have micrometers up to 4”, but I think my telescoping gauge set only goes up to 1.5”. It’s an old General set. I’ll check when I get home.

Just setting the stage. That kit is about a year old. The reason that matters is those of us that track them that was produced before we started having larger problems and may have gone though some type quailty control which we know does not exist when ordering from huztl.

That cylinder sounds like a runner. Cool.

How far out were your cylinders in years past? The first one had scoring and low compression right?

I junked them and you know that. Replacing them made more sense to me than getting the tools. I took one to a machine shop and he said he it was junk and he would not take time to look at it. I am not interested in the least in working on a cylinder to make it right.

The two saws you sold you put a meteor and hyway on them. Your buddy fixed the cross for you.

So why the question?

Add on.
If someone is curious as many have been measuring is done. If you want to see if your 20$ cylinder will cause you trouble measuring would be a good idea. Again putting another on is my preferred shortcut. It's kinda of an important part

The 3 saws I did were all different. The first I put a stock meteor.
The second I put a stock huztl cleaned up.
The third I put a ported huztl on.

The cross is on a 064
And the hyway BB was on a Stihl 440.

The ported saw is running 185psi
I didn’t want to push it with 200.

That was a bold statement...

I do have the tools. Yet I’m not a machinist. Just kidding, no disrespect intended...

Looks like my telescope gauge will be just about maxed out though, but it should work. It says it goes up to 2 1/8. I’ll pull some cylinder measurements when I have a few minutes to spend out in the shop. I’m trying to catch up on yard work at the moment.

Lol, that is cool you have the tools. I love tools.

My micrometer only reads in inches. That’s what I took my measurements in, but I used WolframAlpha to convert to metric.

Piston: 2.123” or 53.924mm
Cylinder Bore: 2.126” or 54mm

I checked multiple spots in the cylinder bore, going from top to bottom. Readings were consistent.

Got to start on my saw today, got crankcase together and did a dummy fit of piston with no gasket and piston hit at TDC
Put the supplied gasket in and it cleared cylinder but only just, measured with thin piece of solder and was paper thin like 0.07”. What are my options without buying another cylinder or getting machined. I have a 2nd steel gasket, is it possible to use both with sealant ? Or could make one from 1mm gasket material and use sealant ?
Not really sure what to do now.
 
Are you certain of the second measurement? They do make a 1mm gasket 1122 029 2306.

A gasket sandwich should be avoided

Wow, that is really tight squish. It seems the cylinders have gone from one extreme to the other. Mine was .065 with gasket. I would rather have your problem than mine. I would get a thicker gasket. The only problem I see with 2 gaskets is it's adding another place for a possible leak, but I am no expert as some of these guys on here are.

Lol, that is so true. From one extreme to the other if he is sure of the second reading. You need more room than a gasket provides. The gasket should be a supplement. But, it is what it is.

I am ready to see some blue ones.

His measurement of .070 with the gasket is a lot. Shouldn’t hit if he takes away the .5mm or .020 gasket. Measurements off somewhere.

I misread the post. I guess I need to get my reading glasses. I read it as .007 not 0.07
And you are right, that doesn't add up.

Yeah sorry I missed a zero I meant about 0.007 with the supplied steel gasket, was a dummy ft with no rings but had it bolted down but not tight either. Had some 1mm gasket material at work so will try that, parts take a week to arrive from local shop but will order the correct lager gasket.
 
That 1mm gasket should put you in there where you want to be as far as the squish. Raising and lowering the cylinder throws around the port timing hope it’s close.
Post some vids when you get it cutting
 
I'm trying to understand port timing. I have never used a degree wheel.
What effect on timing would it have since all the ports are being raised or lowered the same amount as a unit?
