I fix a few engines with flamouts with the Buku cap this seasson Bjarne. Ge one and try!The new front bearing will last alot longer to :-)
Sounds great, Anders
I don't think he is interresting in using more time\money on the engine. As far as I can see, you'll need a specific Buku cap for the Werks engine.
Well, if it doesn't help with the new bearing, I'll block the vakuum hole and test the engine again. As mentioned, its a damn powerfull engine, so it must produce a lot of vakuum
