Help…
My setup:
Malossi 43mm w. Malossi head
13/13 Dellorto w. Polini filter
Main jet 68
Proma Circuit exhaust
Malossi Vario
Pull start
Complete new original contact point ignition(new condensator, inner coil, outer coil wires, contact point…)
2% two stroke oil.
– starts og and rund very well.
…but will not start at all when engine/sparkplug is hot.
Normally I run with NGK B8HS. When the engine is cold it starts right away and runs perfectly. But if I stop the engine and try to start again, it won’t start at all, not untill the engine has cooled down.
Changing the spark plug or waiting until the old one has cooled down, will make it start again – as easy as before.
Changing to a B7HS doesn’t change a thing, the problem remains.
Furthermore the spark plugs only last approximately 100 -200 km…
It seems like the problem started when changing from a no name 43mm cylinder to the Malossi 43 mm cylinder.
Any suggestions???
