At last, some joy with the Commer. We sort of went back to basics.
Firstly, we tried to start her again but she simply would not fire and then would flood with lots of fuel coming out the overflow pipe. We also then noticed a small leak on the carb. So, we swapped the carb for a rebuilt spare that we have and we also removed an inspection brass bolt on the manifold to find that was wet inside. We then tried again and this time she did fire but would only run with choke and would pop and bang, she was missing aswel. We took the opportunity with her running to dribble some oil around the manifold to check for leaks, there were none.
So, next step we re-checked the timing, it was correct. We re-checked the contact gap and spark at tge distributor, this was correct. But, upon checking the spark on the plugs, number one was weak, number two non spark and it went like that for the others. So, we checked each HT lead and found some not good connections at all, these were all replaced. We tried the engine again and although better sounding she was still missing and popping back. With her running, one by one we removed a plug lead, we found that removing the HT from plugs 2, 5 and 6 made no difference to the engine running. These are 6 new Champion Plugs, we found 3 NGK plugs on the shelf so cleaned and reset the gaps and fitted these.
Next push on the starter and you would not believe the difference. Smooth start with no choke, engine running like a clock with some minor adjustment to the air mixture on the carb and best of all, give her some throttle and she doesnt cut out or backfire, just a lovely throaty sounding 6 cylinder petrol engine. I took some video which I will upload.
It just goes to show, get the basics right. Small simple problems can really get you scratching your head and set you back.
Onwards now with getting the body off with the bodywork and chassis to rub down and repair.
