The bike was running previously. It seems to have reasonable compression and initial fire up happens 1st or 2nd kick. As far as I know it has never had an engine strip. I have just removed all the autolube gear. I have blocked the inlet on the manifold where the autolube "injected" the oil so this is not sucking air. Carb looks to be original and untouched so maybe time for a clean and/or overhaul? I have just fitted a brand new kill button - i'll check to see it is not faulty.
Any pointers on the following problem greatly appreciated:
I can start my TY and it'll run for a few seconds and then it kind of "fluffs out" (probably not a correct technical term). It'll start again after a few kicks and do the same again. Using or not using the choke seems to make no difference. Revving or not revving seems to make no difference. It still conks out after a few seconds.
It's interesting to get the different opinions - so far on this thread we have 33:1, 50:1 and 60:1.
I am interested in the reasons people have picked a particular ratio. Was it recommendation? Personal experience? Shop advice? Something else?
I think (at the moment) I'll go with 51.5:1 (probably 50:1 will be easier to measure) as it's mid way between 33:1 and 70:1 and these are the top and bottom of advice I've had so far.
Any further comment, advice or debate greatly appreciated.
I'm converting my TY175 to pre-mix. If I remove the Autolube pump do I have to block the hole on the end of the worm gear (attached to the crank I think?)? Is there anything else I need to watch out for? Any advice/tips/info etc greatly appreciated. Thanks.
