Title: Fuel issue
Post by: scotty110788 on May 12, 2016, 06:16:48 AM
Bike is in final stages and yet another problem! Petrol is getting into the float bowls but not the engine, I loosened bolt on bowl and it come out, my sparks are staying dry. Even on prime, it won't start, if I connect my tank to bottom 't' it wont start, but if I connect to top 't' and bottom 't' it runs so what's stopping it getting into engine? Thanks in advance p.s mixture screws are 2 1/2 turns out

What "T" is it supposed to be connected to?

Everything works as a system, and it doesn't take much to get the system screwed up. There's sso many possibilities as to why you're not getting fuel, it's tough to just rattle off every single one. What all have you done to the bike, and what still needs done?

It's vacuum based 92 model, bottom t connects to petcock which delivers the fuel to carbs, top t is the vacuum  that also connects to petcock, got me stressed lol

Plans once I have it running, to replace brake lines, get a digital speedo, heel plates, paint engine etc...

My mistake, vacuum runs to pipe on left carb on the inside

Top T is vent hose that opens behind air box.
