I had a play with the float level today and no luck.
RMJJ it idles from a choke start,i take the choke off and it idles fine and then loads up and dies.
Drain the bowl and do the same again and fires up straight away.If i hold the throttle about 1/4 to 1/2,its fine then starts 4 stroking,turn the tap off,it still 4 strokes then clears up to nice crisp revs until its out of fuel.
Turn the tap on,fires first kick.
I pulled the airbox off to see whats happening and as soon as it loads up,it is spitting fuel out of the inlet side of the carby.Tap off,clears up and great again.
I used my pressure guage on the inlet and it doesn't even hold pressure.I turn the carby upside down and pressurize it and it holds 6-9psi no problems.
I tried 2 other needle and seats (second hand) and they all did the same thing.
Another thing that i "think" may not be helping is the angle of my carby.It points down at the front because of the conversion.
Maybe the angle of the carby is effecting the pressure of the arm on the needle and causing not enough seating pressure.....(maybe??)
I'll try it again today with the front on a block to get the carby level and see if that makes any difference.
Its a strange problem,otherwise the bike sounds nice and crisp and i can't wait to take it for spin.
I'll check on the price for a new needle and seat....but i'll sus out the carby angle first and go from there.
