I used the correct puller on the hub correctly, without screwing the bolts in too far. i feel as though we're getting a bit too focused on that part. I also wasn't assuming any humor from you fred. I don't know where you got the idea that it ran well without the oil because the whole purpose of starting this thread, along with introducing myself, is to find a solution to the problem of it not running at all. We haven't quite got there yet but that's not from a lack of quality suggestions from you all, it's mainly due to my having no experience in this field at all! Which I guess is plain for anyone to see based on the questions I'm asking. It really doesn't need to be mentioned, so I guess what I'm trying to say is if you're going to post a comment purely based on how sad this is I'd rather you just keep it to yourself.

Cheers,

Ben

shelpi, LW dropped a bunch of manuals and info on me earlier. I'm in the process of wading through it.

Thanks for your input fred 

LW, thanks for the info again I'll focus my scope on the pieces you mentioned

Evening all and cheers for all the advice. I've been on a bit of a hiatus from it  might try these suggestions this weekend. Im hesitant to just start replacing stuff. My first project and all I'm thinking if I can fix it I might just learn something. The carby honestly looks like the newest part of the bike.

I've got the killswitch ready on hand aj 

Pokey you mentioned a fuel ratio? You mean fuel:oil? At the moment 1:0. You might all think this is common sense but ive never owned a bike thats needed fuel/oil mixture. Maybe I should sort that out before we go any further. I'll need some confirmation on what ratio I should be using though.

Gmc the exhaust has been battered and welded and broken and rewelded. I cut after the expansion chamber in a fit of frustration.

Fred I'm not too sure where to find the timing marks, I'll have to have a read of the workshop manual.

Hey Tim, thanks for the offer, she's not exactly rolling yet but we'll get there. At the moment the flywheel is easy enough to get off. Initially I needed to borrow a puller from the mechanics next to where I work but I havent retightenend it enough to need one just while im testing everything

Bloody hell a spiders nest!? That wouldve ticked them off haha. I havent checked but i guess anything possible at this point. Could be a tiny unicorn in the combustion chamber for all i know.

I have tried putting fuel directly into the chamber through the plug hole, you mentioned that ealier frosty. Unfortunately I had no luck with that either. I'm trying all different combinations of the suggestions given as well so you can imagine my frustration! I thought I'd having going by now or at least coughing and spluttering! By now I have got a pretty good handle on kicking the shit out of it too so I don't think that's an issue.

I think the next step is to buy a new spark plug for it and go from there, starting to think its got something to do with the spark or the mixture. I mean at the end of the day I guess that's all it really could be so I'm not really narrowing it down at all...

I'm usually not one give in and ask for help but I'm almost at the end of my tether with this one. If there in anyone willing to lend a hand and finds themselves in the Ipswich, QLD area for some reason I'd be grateful for some hands-on advice. Just to get the bloody thing running!

Cheers for all your help with this one, probably not the best bike to pop my proverbial vmx cherry with to be honest. At the moment there's nothing doing, still not firing even though it seems that everything's ripe for the fire so I'm at a loss. The rag is out of the carby when I'm kicking it, I've got the mixture screw set at 1.5 turns out and after trying to start for a bit the spark plug (which I know is sparking, at least outside the engine) is wet with petrol.

I'm starting to feel as though the amount of time I've spent kicking this over with out it firing is starting to drown the chamber with petrol...

The Woodruff key I guess is the raised section that mates with the flywheel? Yeah that's fine. I'll have to throw the front chamber on, that whole section is welded as one and it's a pain in the arse to remember how it went back on. I might chop it in half to make it easier on myself as ill most probably be getting a new part anyway

Yeah I heard there was a few PE nuts trawling this forum 

In regards to the jet I have removed that during my cleaning of the carby and the jet itself was clean too. I might have a read of some of the material before I get back into it but for now I'm calling it a night.
Thanks for the year too I wasnt too sure on that..

When I had the carby apart I poured fuel through all the orifices to make sure they were clear, choke included. However the choke plunger has some massive resistance to moving. Feels like metal on metal grinding in there, not good. How can this affect the amount of fuel in there? If there's too much fuel in there at the moment should I get an air hose into the cylinder to disperse it a bit?

Yeah I just had another go at it. It scared the crap out of me! Ran for a few seconds an karked it again, havent been able to get it going since. Speaking of timing, one of the parts I took a look at was the stator motor/magneto. The holes to mount it to the case have been lengthened and theres a chance I havent mounted it exactly in the same place. Can this affect timing? Is there markings to line up to? How are some other ways of checking timing in these old suzukis?

Also this might be a stupid question but is the muffler neccessary to run the engine in terms of back pressure? As I have that off at the moment.
