Compression loss and rough running.... Saga

(1/3) > >>

Clem2112:
Many months (years?) of head scratching over my poor running but totally re-built motor may nearly be over ?
Lack of any real pull and bogs down under load.....just about gets to its MoT test.
Re-tracing events prior to this....
The head gasket got replaced again after removing the cover to retorque when some stripped threads in the head meant it had to come off for repair with inserts.
The second gasket was also genuine Honda and the retorque was done after an initial running.
Eveything else has been checked and re-checked over and over.....ignition, carbs balance and float height fine, tappets set, camchain tension ok... Nothing left to do.....but hard to start the thing  !
Once it is going and warmed up it idles quite steadily but revs up a bit like like a twin.... Kind of harsh and the exhaust note isn't right. Plug colour is ok though. No smoke either.
Did a cold compression check with carbs on and off with the same results....170 150 150 170 psi both times. Then did the check after warming up......150 150 150 150.
Counter intuitive I thought....compression worse when hot  on cyls 1 and 4 ??
I can only think the gasket is leaking between each pair of cylinders where the clamping pressure is weakest/ gasket narrowest?
When cold it seems that cylinders 2 and 3 under compression lose pressure to the outer cylinders which are on their inlet stroke....2 and 3 fire with 1, 4 compressing so no loss of pressure?
Is this right?... Assuming 1,3,4,2 firing order is right.
 
Maybe re torquing again will work, maybe not?
Probably a new gasket, seals.....££

Johnwebley:
my thoughts are carb issues,

 check the slow running and emulsion tubes/needle jet etc,

 use carb cleaner and spray out the internal drillings .


 

Clem2112:
Been there already.... Several times.
New needles, emulsion tubes, main jets, pilots, seals, floats !
No keyster stuff either.
....ultrasonically cleaned the bodies too. Bowls are clean.
All passages clear.

Bryanj:
The way you write it suggests points gap/condenser/timing to me

Clem2112:
Even tried putting the points back on......
Have dynatek ignition and dyna 5 ohm coils......times up fine.
Real question is the compression iffy ?
