Guest SuperDave1225 Posted January 11, 2006 Share Posted January 11, 2006 Yes, I noticed my damper oil level was very low (maybe dry???) so put more in (72 4-screw SU's rebuilt by ZTherapy last summer). After doing a piston drop test noticed the fresh oil leaky into each carb's throat....How can I fix this problem????? Thx for everyone's replies...Dave Quote Link to comment Share on other sites More sharing options...
PeterZ Posted January 11, 2006 Share Posted January 11, 2006 Were they overfilled? There's a mark on the plunger. Monitor the rate of oil loss, maybe diligent maintenance will keep them full. Low oil will make for lean running off idle. I recommend using whatever oil you use in the engine and tune accordingly. That way you'll never run out of or have to carry "special" oil.

PeterZ Posted January 11, 2006 Share Posted January 11, 2006 PS when performing your piston drop test try to measure the rate of piston rise. The two suction pistons must rise at the same rate. You don't need calibrated fingers; you can tell if there's a problem with one of the dampers. Quote Link to comment Share on other sites More sharing options...
