I am a recent member. Used to other marques, mainly small 2 strokes. Having just prepared what was a sand racer for the road. Having to add a kick start to the three speed all ball race box. etc. I have done about 30 miles and it goes well. It did on its first run stop after about a mile, and would only then run and has done since on its full advance. My other 2 strokes of which I have er,, several including a twin, do not find timing that critical. Is this normal on a Squirrel ? Its full advance will just kick back a little on starting and will not start unless just short of this. Oil drips early on were quite fast and this might have contributed to oiling up the plugs but it did start immediately when put on full advance. Experiences will be appreciated, I have plenty to learn even at 79.
Do you mean Squirrel, Super Squirrel, or Flying Squirrel ? All VERY different machines and increasingly mis-named these days…
It has a long rear brake torque arm, Web forks and I assume it was a tourer with a white paneled tank. It was a sidecar sand racer and did have a castrol sign bent over the rear wheel. Previous owner had done good work but the gearbox had no kick start and instead of a bush taking the square drive there is a ball race and a short shaft not protruding out of the cover. I have removed the racing seat which extended well over the rear wheel. ( I kept all the bits) It is a re registered one and was confirmed as a 1929 , I believe it appeared not too long ago on the club stand at Stafford. I am learning a lot about Scotts but model types escape me. It has white painted brake plates and torque arm which I have retained. Normally I play with cyclemotor’s of which I have some 12 or so including a twin cylinder cyclemaster. The front brake had about 1 mm drum ovality which I machined out. Its a new experience as Nortons are the other family interests. So far it is quite an experience!
It is very difficult to say what might be wrong, as if it has a racing history it may well have been ‘tuned’ by all sorts of mods to the ports and pistons, which may give more power but also cause tricky starting and poor low speed running. I can only suggest that you let a Scott engine specialist have a good look at it to see what has been done to it in the past.
Thanks for the interest. It does run well but having been involved with motorcycles for over 60 years. Timing ( ignition) never seemed as critical and having no experience of Scott’s I am curious to know if its a common trait as my next task is to replace the magneto chain and set the timing in line with what is there now.
It would be of interest to know what your current engine advance is ?. The standard advance is 5/16
btdc with the ignition lever fully advanced. Thanks
Its running well and I am learning the ” ropes” Hand changing is a first in 65 years . While the weather holds I am using it but before I fit a new mag chain ( which is stiff) I will measure the advance.
