I’m still looking for a correct carburetter for my 1927 2 speed Super and I have found someone who has an Amac coded T15 HYDM – can anyone tell me if this would be suitable for my Scott – possibly with some jet changes etc.? (I believe the M suffix denotes a mushroom type inlet cover which could be replaced by an angled bellmouth)
Hi Brian, I do not think that the carb will be suitable as the amac made for the Scott engine was internally different, with the primary airway in a different position to allow for the relatively poor suction of the engine at kickstart speeds. It would run on it but would probably give poor starting and poor low speed running. We have had this query before and at the time I said that somewhere I had an Amac leaflet with a cutaway drawing showing the difference. I could not find it then but will have another look, and if successful I’ll get back to you. Regards. Brian.
It was me asking before and your previous helpful response was the main reason I didn’t risk the £85 the guy was asking without checking here first. I was hoping the actual codes would prompt a reply. My Amac literature has the code and drawing for the special Douglas Amac they made for the 2 3/4 (and I have a Duggie 23/4 with such an Amac) but the only reference I have to Scotts and Amacs is in Radco’s vintage motorcycle workshop which gives a short undated list of 2 stroke recommendations on page 129 and for Scott it merely says “T15 HY sports jet 31”. I’m sure if they made a special for Douglas they would do it for Scott.
I’m sure you’re right but does anyone have a Super with an Amac that hasn’t had the codes polished off? They are usually stamped at the base of the mixing chamber. There seems to be a complete dearth of information on vintage Scott carbs.
I recently renovated an Amac Carb for Club Member Bill Clarke of the North West Section.
Assuming it is the correct one for a Scott, I’ll put you in touch with him if you like. Give me a ring on 01785 713862 and Ill let you have his ‘phone number.
Hi Brian. Hope you got the info I sent to you by snailmail. I have since found a bit more. Go to https://freespace.virgin.net/elk.engineering/manual.htm#AMAC This lists amac reprint info which should help you. Regards. Brian.
Brian – thanks very much for taking the trouble to copy and send me the Amac info – such helpfulness is truly in the spirit of Scotting. From what you have sent, the code should be T15 HYSP so at least I know what I’m looking for. I do have tha Amac literature available from Elk Engineering but there is no specific reference to Scotts.
Thanks also to Stan – I’ll be ringing you shortly.
