Re: Still won't plane aghhhh.
I did a quick check on your other threads about this motor.
Two things stand out...
1) You have just changed over from a VRO to a non VRO fuel pump, and it does not sound like that went "perfectly". What caused you to change that out? Some problem that it did not solve?
2) As far as I can see you are just going at each "system" and R&Ring at random. If you don't approach this in a systematic fashion, your frustration level will go one way, your bank balance will go the other.
At this point I am surprised that nobody has suggested measuring compression and VERIFYING spark performance....oh, well FR did, but it's amazing how it is the guys who know the most that seem to get ignored. :facepalm: Seriously, if you haven't done those two simple checks, they should only take 1/4-1/2 hour at most. and without those results, even putting in new plugs can be a waste of $$.
Next after that, check your manual for the procedure for VERIFYING the fuel pump output......quantitatively....you want a number.
Then if you did not pop the welch plugs on the carbs when you cleaned them, redo them.
Finally, I may be disagreeing with FR, but I always ran a drill though those high speed jets..,..but there is a CORRECT SIZE for every jet, and in my case it was a numbered drill (forget the exact number, but I think my jets were 52D, and the correct drill was #55) that the manual spec'd. I think FR is really saying, don't scratch, bend, fold etc. the inside of those jets as they are fussy and need to be right on size and smooth. That would be my first suspect in what your problem really is. I redid my carbs once...they looked pristine...but there was a "crust" of varnish-like crap inside the jets....they "looked" fine, decent diameter and smooth...but were not!
