Hey All,
Again, its been a while since posting, but life ha got in the way of my hobby!
Fired the engine up again after looking into the valve timing, and resetting it as I thought it might be out but it seemed OK and with an 18x12 prop (may be a bit much) I was getting 6000rpm.
I am still having some propblems getting the carb settings perfect, and have tried two different ignition units to see if there is any change but I am still not getting a good balance between a decent idle, good transition and good top end. I am going to prop it down to a 19x8 or 18x10 as it has a new piston and cyl, so might need a little more 'run time' before it performs best.
One thing that I have noticed is that there is a LOT of fuel 'spitting' out the carb trumpet. I have a NGH38 engine which is similar in capacity, and there is the normal 'mist' that appears in the carb throat from time to time, but the OS has a lot of droplets there, and it makes a huge mess of the back of the engine. It seems excessive to me. Has anyone else noticed this?
Regards
