Took my carbs off and had them rebuilt...5weeks! later got them back. went to put them on...getting gas thru new petcock and fuel filters into bowls of carbs, but no start. She does start when i spray starter fluid thru the air cleaner...put on new intake tubes, no change. i believe the problem may be with ?vacuum? hoses (or breather hoses?)...at back of carbs are 2 hoses plus fuel line from petcock...front of carbs has 1 hose nipple...can anyone tell me what hooks up to what? dealer pics show 1 hose from sending unit at tank...I've got 2 hose nipples on mine and assume one is a breather...any help would be appreciated...thnx

The front will be the vacuum for the petcock. You'll need a hose there to allow the petcock to release fuel. The hoses in the back are two vent hoses and one fuel line.

First thing, put the starter fluid AWAY unless you want to trash your engine.

You mention fuel filters (plural). You should only have one on the fuel line and if it not the correct type it will not flow enough fuel. Lots of folks have different opinions on inline filters, I personally do not use one. The screen in your petcock should be good enough unless the inside of your tank is rusty. What parts were replaced on your carb rebuild? Many of the aftermarket kits are junk or low quality and will create more problems than they cure. Did the rubber o-rings get replaced?

Go here for pics of your carbs showing the vents & vacuum line locations.
