A THICK coating of carbon, like 2-3mm 1/8in over everything in the chamber & piston top. I think/guess it won't be pretty hard carbon like a high mileage carburetor engine, but a lotta light soft play-doh like stuff built up from burning lots of oil. Then again, those numbers are from someone se...

Thanks for the pics.
WOW, that spring comp., you've spent a LOTTA time with it even if you do the removal with a hammer & socket!
Weld a nut & use your drill??

Also, a nicer surface might increase its sellability.

Flatlander?
All the intermediate gears are really handy if the terrain ain't flat!

Wet or dry? The compression test? That is REALLY high, a happy gauge or a LOTTA buildup in there. Can you see anything in there? Do nothing or do it completely or just the pan & the pickup ONLY to make sure it'll have no pickup problem no matter what else is wrong. The cleanliness/flush/douche s...

My apologies to Mr Bradshaw who is in no way extinct, only his website which continues to live at web.archive, an invaluable resource & treasure.

Takes a little thought to get your head around the timings but it is invaluable, thank you.

Where's it from??
Thanks jondee86, can count on you to always deliver such great diagrams & pics, besides all them words!

Still got stocks around?
I wouldn't consider any cold and/or hot start problem much of a cam problem.
Other then that is it OK?
Have any other idiosyncrasies that you've accepted but maybe might not wanna live with?

Not WAG's.

Less weight & move the engine back. If you've got a min. weight, add it back under the seats. // Also, was thinking a NO2 bottle, a small one under the dash or gutted heater/AC box, like the bottle for paint ball guns. Elec switch/valve & run thin nylon/teflon tubing inside the heater hose. ...

Assuming they're stiffer, higher durometer, I'd mount'm, engine/vise/frame and then twist/move/whatever the other end with an adjustable wrench or drift punch in a hole and just go by their feel.

Checkout YouTube for AC compressor shaft seal replacement/leak/fix.
Some are easy, some ain't, some special tools, some not.
Keep it CLEAN, no surface problems, scratches, nicks, whatever, on the 2 flat smooth surfaces that push against each other, and the shaft & housing.

What's the specific question?
oldeskewltoy has had A LOT of threads about heads & checking volume on this site, and at least 1 gotta be about that head and if he hasn't answered it, it's not a good question.

Thanks.
Beautiful.

... I have to try several times to crank it, at times it cranks but with a very low RPMs making a noise as if it getting limited fuel. Can it wind out 2nd & 3rd gear, 5-6K rpm without any problem, before the problem starts? If so, there is no fuel problem. There may be a not really a fuel probl...

Around here there isn't a specific number, just a sticker on the pumps "May contain up to 10% Ethanol'.
I think most all decay stuff has been BS, but it doesn't age very well at all & really turns really nasty.

nyberrg wrote: My guess is due to the ring gap being too tight, maybe?

No.
And I'll say that is not a guess, and I'll say that the amazing jondee86 & oldskewltoy would never guess that also.
Water corrosion, sure, but never seen one localized like that unless the engine was leaning over.

I wish I knew what that pic is.

New bolts won't be as smooth, thread & head, as old so you might actually be tightening it less then before.
Yes, thin gasket will retard the timing, head cut even more. How much? IDK.
Good luck.

IIRC, I could give the heater a quick feel while driving, but you're RHD. Just a one time confirm the heater's venting is open & what's blowing is what's happening in the core. The heater's outlet goes right to the thermostat and cools it down, slowing the flow. That's as much as I'm able to gue...

Maybe somewhere in the below...

All the above. Yours might only need some tuning. clean its terminals, clean ground if it's 1-wire, clean its relay terminals & contacts, adjust it. That adjustment screw on it, self tapping or threaded& locknut, will change it quite a bit until there's no sound at all at either end of its r...

OK.
I'd think that big aluminum ridge around the seat would do more then a bit, but I've got 0 flowbench experience and can only go by what looks aerodynamically pretty to my eye.
Thanks.

Water pump failure is extremely rare, I've never seen one but I've heard of Many water pumps being replaced for reasons only slightly related to it. Not that water pumps don't fail, they leak & their bearing goes bad, but failing to actually pump is almost unheard of, a few have broken impellers...

Thanks, looks nice & clean,
Looking at those 3 valves through the intake is always a neat thrill!
Were the other cyls clean & dry & smegma free?

Is there going to be any more finishing/grinding the comb chamber, all the area after the 45, on the 60 to 90 and the ridge around the seat?

Heatshield?
Contact after abuse counts, like a little kiss to the dirt & coating, or like it's been hammered on?
Rebuilds not inspected and/or disassembled are iffy, otherwise great & can last a long time.

Big chamfer, still need a ring compressor?
Thanks, beautiful work & pics.
