TEW47 Posted January 31, 2007 Share #1 Posted January 31, 2007 I have been using Motion Pro carb stick for several years and had no trouble syncing the carbs. The last two times I ha ve tried to sync the carbs I could not even get close. Today the mercury was sucked up into the carbs twice at idle. Have sprayed the carb boots with WD40 and it didn't make any difference in idle. Anyone have andy ideas. Also I replace all sparkplugs.

timk Posted January 31, 2007 Share #2 Posted January 31, 2007 Were you blipping the throttle??? Was the mercury really "dancing around at idle??? I ask, because there should be a snubber(reducer)in each line to prevent that, and to smooth out the pulses. Link to comment Share on other sites More sharing options...
Eck Posted January 31, 2007 Share #3 Posted January 31, 2007 sounds like your missing a hose restricter, for the murcury to be sucked out....... Link to comment Share on other sites More sharing options...
Yammer Dan Posted January 31, 2007 Share #4 Posted January 31, 2007 Sounds like you are missing one of the restricters. Link to comment Share on other sites More sharing options...
TEW47 Posted January 31, 2007 Author Share #5 Posted January 31, 2007 What is a restrictor and where is it? It was at idle when it sucked out the mercury. Will try to run commpression test and leak down test maybe tomorrow. Gene Weir Link to comment Share on other sites More sharing options...
Yammer Dan Posted January 31, 2007 Share #6 Posted January 31, 2007 Each tube should have a restrictor in it which is a litle thing that cuts down the flow through the tube. There should be one in each tube and they are very small. Link to comment Share on other sites More sharing options...
Johnh Posted February 1, 2007 Share #7 Posted February 1, 2007 I had the same thing happen to me last summer, and it was my own fault for following the shop manual instructions. The they show the wrong screws for the cylinders indicated. If you did what I did the number 2 carb is closed tight and number one is open. you will need to get a base line setting on the 1-2 carbs and start from scratch.

TEW47 Posted February 4, 2007 Author Share #8 Posted February 4, 2007 Installed the hose resistors, and it did not help, sucked the mercury out in about 30 seconds. Emailed Motion Pro , they said I a broken ring or a burnt valve. Local shop does not have any idea until a compression test and leakdown test is done. What do youall think? I guess that what I get for bad mouthing HDs so much. Gene Weir Link to comment Share on other sites More sharing options...
Freebird Posted February 4, 2007 Share #9 Posted February 4, 2007 They are probably just WRONG WRONG WRONG. I've heard and seen this happen before and it had nothing to do with rings or valves. They were just out of adjustment enough to cause it to happen. Bob Dakin had the same thing happen. He finally used the Carbtune and got them adjusted just fine.
