Hi Troy thanks for your recent answer,

I have another two questions:

1. The clunk included with the engine how does it work really? It has a hole at the side of the fuel tube but not on the other side. Does it have to be changed after a number of flights? The sponge part of it seems very fragile to me.

2. I have noticed you insist on putting oil on the cam gear before the first start. Unfortunatelly I bolted the engine on and set up everything without doing this. Is it possibe to remove the valve cover and drop oil through the cam push rod followers from the valves?

Looking forward to your reply,

Thanks and regards,

Nikos
