hi there
i have a 1979 xs400 , it has a non vacumm fuel tap on fuel tank and both vacumm pipes on carbs have been sealed. the compression is 145psi each cylinder.the timing is 100% spot on and replaced both HT coils so there is a great spark on each.
i cant get the bike to start , the only way it will start is by injecting a small amount of fuel in to each cylinder
(wet start) then it only runs for about 30 seconds.
it is like the engine is not sucking fuel through the carbs to the cylinders.
(the carbs have new needles and jets fitted)
can any body help.
cheers dave
