Yet another Petter A1 !!

Hi All
Another Update.
The piston ring's are ok as is the groove's in the piston
I am using the magneto of the other petter for now nice big fat spark
And using the manifold+carb of the other petter for now
I have had running quite well she's a little fussy on what speed she go's (must be a female )
Found out what that banging noise was it was the flywheel working loose redid the gib key so far fine
She is an easy starter. Now i need to mount it better i have some wood+wheel's.
Many Thanks
Andrew

with patience if you get really stuck, you can ship the mag down here and I'll put it back together for you or someone up your way may be able to help. Its better if you can se it being done, then you know for next time

I hope there is not a next time !! on a plus note petter is running better
I will have to decide on what to do with the other petter spare's or spending to get her to run again depending on cost
Cheer's for the offer of help Blackmanvan thank you

Hi All
Another update
After the last run i noticed the head gasket was leaking a little so off came the head. And discovered it had 2 head gasket's on i mangled one getting 1 off the other came of easy look's like it reusable
I using the head gasket of the other petter look's in better condition.
Are there any torque wrench settings for the cylinder head or is guess work
I also redid the carb it's still running rich so hope fully when back together it will run better with more compression
then get mixture right with a bit of luck

Not sure about torque wrench settings, I usually use the torque wrench anyway, but set it close to it's lowest setting, just to get them all done up the same. Then I up it by about 5 Lb/Ft & go round them again & see how it goes. If you think it needs more then keep going up in small increments.

If you haven't got a torque wrench then probably just use guess work, but I prefer to use one if it's available (for the sake of a few minutes to dig it out from it's hiding place).

Someone may have the correct figures for you though, but many of these old engines didn't specify any for head bolts, they just remind you to tighten them down in the correct "flange tightening" sequence. (I have at least 4 different old engine manuals & I don't think any of them give head bolt torque figures).
