Greetings all - have been refurbishing a 1978 Montesa Cota 247 thats been laid up in dry storage for 20+ years! 

 

Generally it looks in a reasonable condition and most work I have done has to be honest largely unnecessary (checking conditions and cleaning).

 

So added petrol and it fired up 3rd kick! :-)

 

However once warm/hot it refuses to re start.

 

My first though was that the crank seals had hardened and were loosing pressure once hot (however there is no smell or petrol or residual mix inside the ignition case). 

I'm still intending to change the seals just as a good idea, but I haven't yet taken the clutch side apart.

 

However this brings me to a question and a problem 

 

Question - any ideas on the not starting when warm/hot issue (leave it to cool and it starts firs kick)

 

Problem - the nut holding the Motoplat stator in place is solid and will not budge, is it a left hand thread, or are there any ideas around to shifting it? 

 

 

Thanks :-)

 

I'd check the condenser. Or directly replace it for a new one. Best if you use a modern electronic one.

 

The flywheel nut should be rotated clockwise to loose it.

OK thanks for the info on the flywheel nut once I knew I could pull harder and it shifted! 

 

Any suggestions on a new condenser?

I know it's written in spanish (it's my own personal blog), but Google translator can be of help. 

Thanks for that looks like a easy modification :-) 

Indeed, it is. And a very effective one, I think.

Now looking to buy some capacitors as they come in bags of 5 anyone else one to join in?
