Problems I faced : -

1) erratic idle and flames out easily
2) When she is at operating temp (125-135 C), she gets difficult to start. I have to open the fuel lid, insert the glow starter and only then will she starts. And after she starts, I need to gun her to clear the bottom. If I do not gun her, she bogs and flame out. I know i need to lean the LSN to clear this, but at 130 C, I still need to lean the LSN? LSN is about flush, looking directly at her, she is about 3-4 o'clock.

I guess 1 and 2 are related but I have been chasing those 2 for days and nothing that I do seems to get me closer to the perfect tune.

No air leakage. Pressure hose is about 10 inches. Clean air filter.

Anyone knows where I can get Nova shims part no 03005xl, 03003xl and 03001xl?

Your assistance is greatly appreciated.

thanks
