fv1609 Posted October 17, 2010 Share Posted October 17, 2010 Humber Pig engine after new valve seat & skimmed head. Sounds a bit noisy with no rocker cover & perhaps a bit rough. But when you see the last frames it doesn't seem that rough, all things considered! Compression now 100psi on all, instead of 90 & #4 cylinder on 20!!

fv1609 Posted October 17, 2010 Author Share Posted October 17, 2010 Andy usual silly mistake of not blocking off the vacuum take-off on the manifold. I twigged it once I realised the removal of the rear three plug leads made no difference. I got misled earlier as on that manifold the spindle supporting the accelerator pump diaphragm was sticking. This was after I cleaned it, but the crud was in the casting just on that side. When this didn't improve it I swapped it for another carb, with no improvement then realised my error. W&P? I need to get it ready for Christmas. Quote Link to comment Share on other sites More sharing options...
