Invader will not run

[Vader19]

I will pull the pump back apart and check or make a hole when I tear back into the sled.  I’m going to have to pull the motor back out of it to deal with a leaking water pump.  The carbs are Mikuni 39.5mm units and I have had them apart twice for cleaning.  Can anyone tell where I can find the original jetting information for the Invader and 4/6, I would like to compare them to what this currently has in it.  I am not having any luck finding the flanges for the twin pipes so was thinking about making my own, if someone could post a pic of theirs it would be super helpful.  Thanks

Hi as a recently just bought this 1980 invader LTD the carburetors, I pulled off one says 36/90 the other one says 36A/ 60.. The carbureters  are identical they are Econo jet carburetters I’ve taken them apart and ultrasonic clean them and they are identical in every way but the numbering is wrong according to this  post, can someone please update me on these numbers. Thanks

1978 Invader carbs are marked 36/60, not sure about the A on yours.
