As the title suggests, the engine has been rebuilt and a pair of brand new HS6 carbs with SM needles installed.
Its really hard to start, to the point where if i didn't know it actually ran i would probably give up. Choke doesn't seam to help this. Once running its ok, hot starts without hesitation but the idle hunts, fluctuates from 800 to 1000.
Personally i thought it might be a vacuum leak? i have tried spraying possible areas with brake cleaner to see if the engine idles up however this is tricky as the engine idle fluctuates every couple of seconds, like a heartbeat.
Im not a massive carb guy, hence going with brand new, just wondering if anyone might know?
