The Perry Regulating pump of course will help.

I just checked and the main needle (I use only the carburator mounted needle) and the sweet spot for my engine has been around 1.5 turns open from fully closed.

I have no idea what any manuals have suggested I just opened the needle up perhaps four or five turns initially and arrived at the setting where it is now by pinch tunning. It has been quit stabile at that setting.

Let me describe the priming technique I use, by the way mine is a side mounted 1.8 also. First I open the throttle barrel completely and then completely cover the venturi (not just covering the exhaust outlets that won,t pull the fuel). With the throttle open and venturi covered I will then pull around five to ten blades and I do it untill the fuel is completely running out the venturi and my finger is soaked.

Its at this point that I either use the starter or bounce start the engine by bumping the engine backwards aginst compression with the spinner.

Hope you have better luck.
