Ok…
New head fitted, all good there 👍🏻.
New fuel tap and fuel line, so there is fuel in the system and no air bubbles in the fuel line. 👍🏻
BUT…
Starts and idles nice. 👍🏻
But when riding, it will not go through the revs unless choke is pulled. 👎🏻 Then it runs fairly good, even though it doesn’t do more than 80km/t in fourth. 👎🏻
So I’m pulling the carb one more time, but cannot see where the issue is….
Any suggestions??

Has the fuel issue been resolved, is the carb bowl being filled as you’d expect?

Has the fuel issue been resolved, is the carb bowl being filled as you’d expect? Apperantly. Fitted the 3rd fuel tap, and now the fuel line is filled all the way from the carb up to the fuel tap. That said, I don’t know the exact level og fuel inside the bowl, but when I checked the bowl and floater, it was all ok. But will still not run properly… 😝

Any air leaks? Have a look at the fly side oil seal to see if its been weeping , I have bought duff oil seals in the past ie 20.6 mm instead of 20mm

Have we asked what jets are you using and is it a standard air filter, just thinking if my understandings correct when you use the choke you reduce the air and and add more fuel to the mixturet

No air filter. The jets are the same as the engine has been running flawless with since 2013…

And every item is ok And you have no air leaks And the filler cap is ok And all seals are ok And the carb and manifold are correctly fitted And ignition is ok Give up

Do a proper leak down test. You thought it was all fine before and it had a warped head
How’s the rotary pad?

I know.
Insanely frustrating! 😂
But yes, I’m going to pull the engine and do a leak test.
The rotary valve isn’t an issue, as it is reed. -but checking the reed petals ofcourse.

Update.
Pressurized the engine, and guess what!?!
Yes, an air leak… 🤦🏻♂️
A leak the the cylinder base, so I’m removing the cylinder, cleaning it all and fitting it all again with some sealant…
So we’ll see if that cures it… -guess not! 🤪

Final update! Got the choke-assembly today, and 10min later it fired first kick! 🤗 Took her for a spin, and no trouble at all! -a bit rich with 50 idle jet, but will be adjusted and then she’ll 100%! Apperantly the carb arrangement was the issue… Case closed!!!
