Re: Auto advance?

The PO had the distributor rebuilt not long before I purchased the car and I have done hardly any miles. Furthermore, the car stood unused for over 2 years so lack of use could have caused the bob weights to sieze up (if this is what's happened). Thank you Brian for the most interesting information,...

Re: Auto advance?

Thank you for the responses, I think there is some confusion with regard to my car which is a 1935 972cc Singer LeMans Special Speed and appears to be timed differently to the standard 9HP sports. According to the manual kindly forwarded by Mike, the ignition fires at half an inch BTDC and not at TD...

Auto advance?

Me again! I've now sorted the oil leaks and had a good 30 mile run out today but was a little displeased with performance. When I checked the timing, there seemed to be little or no advance as I revved, I know there is no vacuum advance but is there a centrifugal advance? an attempt to twist the rot...

Re: Adjustments on distributor drive housing

I thought I'd closed the topic but there is another development. It seems that the only problem with using an oil seal in the on the dynamo pulley shaft is keeping the shaft dead centre (within 10/15 thou for the seal I used). I therefore made a tool (see picture) to centre the cover on the shaft be...

Re: Adjustments on distributor drive housing

Thank you Brian, I'm on the case. I prepared for a bit of a battle to get the seal out of the cover only to find it to be a very loose fit, which surprised me given the PO did the job! so it could be that oil was leaking past the outer edge of the seal - I'll never know now. I'll use I light smear o...

Re: Adjustments on distributor drive housing

Just to update and close the topic. There was no "Mexican hat" thrower fitted but the previous owner who was a competent engineer, had made a new cover and incorporated lipped nitrile rubber seal (24x35x7 mm) which had worn. The engine was rebuilt about 20/25 years ago and whilst I've done...

Re: Adjustments on distributor drive housing

Ahh, I see now - thank you I was confused by your reply at first, then I realised you were referring to Neil's photographs. I've had the Singer for over 15 years but it has had little use and thus I have not needed to carry out any meaningful work on it until now so I'm on a steep learning curve, es...

Re: Adjustments on distributor drive housing

Image as requested. The leak is below the place I am pointing at with the screwdriver. The frayed fan belt is another investigation required!

Re: Adjustments on distributor drive housing

Thank you Peter, I actually found and downloaded those very photographs during a recent search of the forum! I now have a greater knowledge of the subject! The remaining mystery is - how do I adjust the fan belt please?

Re: Adjustments on distributor drive housing

Thank you Neil, what I said about the fan was only an assumption based on me reading an article that mentioned the fan followed by the words "if fitted". The leak only occurs when the engine is running and looking from underneath with a small mirror, I can see the oil running down the cove...

Adjustments on distributor drive housing

I have to rectify a severe oil leak on my LM SS from the fan belt drive pulley shaft seal and I notice what appears to be three adjustment slots, two at the end of the top two bolts holding the generator on and the other a little lower down behind the fan pulley. Will somebody please tell me what th...

Re: First Run of the season 2022

Well Mike, If you can't go a little (or a long way) off topic on your own forum - who can?? I've read what you say with great interest and can only say I am absolutely stunned! I signed up to the SOC FB group (with an alter ego!) with great reluctance because I actually loathe everything that Facebo...

Re: First Run of the season 2022

I only recently found and signed up for the Facebook "forum" but I don't think Facebook is a suitable substitute for a forum and I'm surprised that the SOC has opted to go that route. When it comes to exchange of technical information, a forum such as this is the only way forward so long m...

Re: Gear box noise and primary gear bearing fixation

I'm having a similar problem except my LeMans Special Speed jumps out of second gear on overrun and I am currently addressing the problem. I haven't taken my gearbox out yet, I am rebuilding a spare gearbox that I have. The bush in the gearbox I am building is intact but i can't find what the exact ...
