thanks Max, the old girl already runs, but was lacking in power a tad, cut grass ok but I had to rev up to keep going which meant that I had to run behind to keep up.. not good at 77yrs old, I had set the timing using guesswork by moving pston 'back a bit' from tdc...thought it might be a fuel prob, swapped a fuel tank and carb set off another motor, but no change, so suspected my timing was out a bit, I,ve reset the timing to 5/16 btdc, using the old 'blutac in the fins with a paperclip to a pencil to mark tdc etc;' trick, and will go to the 5/32 tdc, I'll post with results, thanks again.G.
