Thanks Grumpy. I most definitely used compressed air after each go of soaking and removing the oil build up. It appears the engine is running better after following this process.

It is a pleasant engine to start, it is idling very well. Full speed is great as long as you get the throttle adjusted at the right full speed setting.

I use the following process when using the engine and wouldn�t mind your thoughts as it is still a little touchy when adjusting the engine to full speed which makes me think the choke mechanism might be a little sticky. I could be wrong through.

1) Start on choke, wait a few seconds and then move the throttle to full speed, this hardly ever provides any issues. Full song sounds great.
2) Move the throttle down to idle , it then ides really well
3) Move the throttle back to full speed and I actually have to push the lever onto the choke for a second and then adjust it back to full speed. Following this process gives no problem������however if I push the lever from idle to full throttle it hunts. Follow the process of moving from idle to full speed by giving it a little choke then back to full speed and ����.no hunting.

Maybe I am on the wrong track but could the choke be a little sticky?

All the intake gaskets and brand new BTW.

I haven�t got a Jet drill kit so that might be a good idea to give the mrs for a Christmas present.

Getting very close now.
