Hi All,

Once I get the right oil pump fitted

how much 2t oil do I need i.e. how many turns on the oil pump cable after it is correctly adjusted?

I have a "bolt on" can micron, 10W carb, ledar nozzle, K&N and 210 main (to start with as this is what the ledar instructions say)

I think I read somewhere on here that a good starting point is one extra turn per "up jet" size.

Is this right?

If so I need 5.5 turns i.e. 210 - 155 (jet size)

Don't worry Gaz, I haven't ruined it

. The air jet isn't fitted.

I'll stick with the nozzles and 210 till I have tried it as this is what ledar recommend.

If it doesn't work I can always put the old nozzle back in.

Cheers

Andrew

Here is a snapshot of the Ledar fitting instructions which shows the nozzle is suitable for a 10W also and their recommended jet starting point.

I'll keep you all posted on how I get on. If I can get it to run as well as my MK1 did back then I will be well pleased.
