ok thanks. rollers are next on the list.
right I've had my first attack. Not so successful unfortunately...here's what I've managed:
Removed the carburettor after a bit of a fight - I've managed to destroy one of the bolts holding the throttle cable on to the carburettor. Will have to find a replacement later.
Got the thing open and generally it looked pretty clean. I did however notice the following:
1. The gasket is considerably larger than the channel that it is supposed to run in. So much so that it was impossible to get it to sit inside before reassembly. Is this normal?
2. The air intake (from the air cleaner to the carburettor) was not correctly fitted and there was a bit of dirt inside the carburettor immediately where the air intake pipe attached.
3. The main jet seemed fine, but I couldnt tell what size it was. I replaced it with an 82 anyway, which to the eye looked to have an identical sized hole to the one I took out.
4. I cleaned the idle jet. Then I screwed it back in and it broke (newbie error - overtightened). The hole seemed intact it just split at the top where the screwdriver inserts, so I just left it in as I don't have a replacement at the moment.
5. Fuel lines all seem fine but I replaced the fuel filter with

So I put it all back together again and tried to start.
Same problem, no change at all. Won't start on the electric start. Takes about 10 kicks to start on the kickstart. Except now I have a new problem:
- when idling, it will idle for a little bit, then rpm will go lower and lower until it cuts out. Runs fine as long as revs are high.
Does anyone have any idea what's going on? Next on my list is to check the valve clearances but I can't do that till my tools arrive next weekend. Also I'll probably have to replace the idle jet now I broke it.
Any suggestions?
