I have an issue with my 1275 at the moment. It has recently come out of hibernation and has decided to develop a sputter and loss of power at low rpm under load in 3rd and 4th mainly.
I have cleaned the carb out and fiddled with the tuning a bit which doesn't seem to do much if anything.
I have also cleaned the plugs and ht cap to no avail.
I have not changed the timing as that was fine last year and it has not moved since although if all else fails I may have to give it a go.
Do you guys have any suggestions on what else I can try?
Thanks in advance
