262 rebuild

[paragonbuilder]

Never did check squish yet but my final numbers are
103.5
119
72
Hopefully that works, I'll post some pics later and as I go.

If you're planning to delete the gasket, make sure you check the squish, they tend to be .010 or less

So I have read lots of different options on transfer height anywhere for 116- 126 is there a go to number or is that up for debate?

It's more the blowdown number that dictates transfer height and that's relative to the exhaust height.

The amount of blowndown is up for debate/experimentation, usually 17-20 or there abouts so you're a bit tight but should be ok.

Check your squish.

Sand your band with an old piston till it's 20 with no gasket.

Make a .020 popup.

Drop jug over it until squish 20 again.

Relieve the intake skirt till it makes the intake around 76-78.

And don't fark with those transfer tunnels too much. The work of art in the great jugs is right there. It takes a lot of time and practice to touch up the Mona Lisa and make it look better, if you catch my drift.

BTW, how are you measuring your transfer height? If you're looking through a port or the plug hole only, that's just a rough guesstimate of where to stop your degree wheel with a ring placed in the bore. The only accurate way is with a ring pushed up by the piston and a pic to feel where the transfer is opening.

If you want/need the base of your jug cut, I'll do it for nothing. Just pay shipping.

104/120/76-8 are very good numbers for a 262 IMHO. I bet you're happy.

BTW, which carb will you be running.

I checked transfer with ring the last time when I got 119. I have the hda 87

Anyone seen this before I have a meteor piston ( same height as oem) and my ks cylinder and I have .019 squish with no gasket I checked several times because of what everyone says they should be. Seems my squish and timing are a bit different than normal.

 

[Johnmn]

Timing with no gasket
105
122
70
?????

My KS was around 0.009" without gasket (meteor piston), and those Mahles I got is very similuary in squish, I used Plastigauge when I did squish test.
My experience with soldier is that if they isnt soft enough they give a false reading, around 0.003-4"

 

[Johnmn]

I used soldier I'll try it with Plasti gauge and see what I get

 

[Johnmn]

Checked with Plasti gauge and got .019 twice. Weird jug?

probleby a bit off compared to what others have but it is what it is
Good thing is that you dont need to sand the squish band as most of us has to do.

This project has been put on the back burner. Messed around with the cylinder some more last night ended up at
104
123
73
I put the cylinder on and am gonna try it

 

[rattler]

I just got thru with one 102/117/79

Intake at 73* makes more sense without the BG. My brain back fired when I red that you lost intake timing with the gasket removed.

I revamped my degree wheel I think my original stock numbers may have been off a little. But now with the drill chuck it's much better

 

[XP_Slinger]

Good deal. Never good to have your degree wheel lying to ya, could send a good cylinder right down the crapper. Glad you got it dialed in.

 

[Johnmn]

Well I finally got this saw together and it won't run at least very good. It has a new carb kit, saw it just super pig rich. Metering arm? Any thoughts would be great!

 

[dustinwilt68]

What carb are tou running 120 or 87?

 

[Johnmn]

87

 

[Johnmn]

Maybe I didn't get something right with needle and seat. Turning h & L screws do nothing just dumping fuel. I'm wondering if the needle is no seating and is just allowing fuel to just dump in? I don't know just thinking
