Cylinder shop figured that out. Unfortunately I didn't get the specs.

Yes. Needed the valve stem height because i was installing new valves. Had to have the exhaust taken down 20thou and the intake 10thou to put me in the correct shim range. 👍

Dhla 45s, front carb vacuum real high back carb fine. Solution ??
s1guy replied to s1guy's topic in Fuel System/Carbs
Ok guys. Popped the bolts off and checked both choke/enrichment pistons.Both working and not stuck. Throttle plates are both in the same spot when closed. Checked those by looking at the progression holes. But my timing belt def jumped 1 tooth. Belt is back on correctly and checked the belt tension. Spun it 4 times and rechecked the tension every revolution. Will check all plugs before i start it shortly to make sure i have spark on all 4. Wish me luck and thank you for all the replies. Greatly appreciated.👍👍 -

910esprit, even if i pull the front carb balance lever back the vacuum is pegged. It seems as if the throttle plates aren't closing all the way. -

Ok checked mounting plates and manifold for leaks. No leaks. Rear carb vacuum is good. Nothing i do will bring the vacuum on the front carb down. When i give it some gas it comes down a bit but at idle the vacuum on the carbtune is pegged. Throttle plates ?? -
