Presuming ''spraybar'' means inlet to the carb. I think I will try the 55AX inverted (or at 225 Deg when seen from infront) as recommended by the manual. Just to cutout other variables, I will use my old 55AX rather than a new one. For the Topstar though, I am thinking I will try out someone's 91FS on trial basis before I buy one for myself
Will keep posted about the results.

Ameyam,
Don't presume anything. If you're not sure, ask.
The carb inlet is where your fuel line connects. The spraybar is in the middle of the carb throat. That's the tube you see going across, when you look down the carb at WOT.
If you can't get the carb properly adjusted, find some way to open the fuel tank, or buy another. Skipping something because it's too hard, or takes too long, will only extend the time it will take to get your aircraft flying reliably.
HTH,
EJ
