What i did so far :
Replaced electric part of the fuel pump and the "filter" - works lot louder but no change.
Then that WOT w/o load got me thinking about coils and electrics.
Took the plugs out to find that on first cylinder it was black and diffirent from others. Checked the coils , chcecked the spark (just on cranking) and it was good and then i thought maybe the cap is loose or it shorts at high rpm.
Replaced coil on first cylinder and gained lots of power + now i was able to get it up to 13.5-14k rpm ubder load before it sputtered - atleast thats how it felt (only on 1st and 2nd gear - didnt have much room and didnt want to loose my license lol) and WOT in neutral now hits the limit
Ordered Voltometer - will mount it on dash and connect to diffirent places to see what happens to voltage when i hit that RPM wall.
Also will order fuel pressure gauge + vacuum gauge (but dunno when - Will try to get you all up to speed).
So if you cannot hit the real governor in neutral chance is its one of your coil / plug or connection there.
Maybe ill just go straight to flashing people for good AFR test and reflash.
got whole winter to get some cash for it.
