Message: <blockquote data-quote="krakum1967" data-source="post: 125701" data-attributes="member: 3691">Okay,, first the promised carb pics.And, the results.  It runs MUCH better.  I get it to idle, I can make adjustments now.  It only fell down or stalled 3 times out of ten test fires.  Trust me...this is a HUGE improvement.  I am definitely rich, I dont have to read them I can smell it, but at least I am getting a true read opf thje odors.  The smoke (its a gas smoke) is way down, but it still smells rich.  It is running cooler.  And it responds to throttle.  It will not throttle up cold, but it does idle.So as I was getting close and dialing on the air/idle and on comes those annoying squeaks again.  Like someone playing a trumpet without the horn.  Real loud, high pitched, bouncing everywhere, low volume whistle.  And then it became louder,,and then there was a harmony.  Now either the oldwing is getting really good at alienish high pitched interpretive jazz, or I have an OBVIOUS leak.  So I start tracing. With that loud of a whistle, I should feel it too. So I start following the noise and the vibrations down with my hand.  Joints are fine, the woody is fine, all the carb joints are fine, the carb is fine, the noise is definitely right off the block, not in the block.  SO I grab the number 3 runner rubber sleeve, and squeeze, and sure enough, I changed the whistle....so once again, krakum sits down, pulls up the tv tray, you know the one that has the fresh plate of "I was told this". Now I have to live with the choice I made to disregard it....lol...Yep Joe, those wire lined runners are junk...do NOT use them.  As they conduct heat (And they do, its was cool how it was heating the plenum) the wires inside heat themselves back to the surface of the rubber hose, causing micro slits in the rubber which whistle something fierce when all four tubes are kicking in....lol....yea, and as you torque down on the wire with the clamps, it cuts into the rubber too.  So you can squeeze the clamps and cause it to whistle too.  Now that the top end vacuum is good, I can hear these last (I hope ) leaks relating to the rubber hose I used with the internal wire.  Yea, this is not good runner material in spite of being fuel resistant.I need a good hose number for a 1.5 inch inside diameter radiator hose that I can cut into 4 sections, I would like 2 of those cuts to have like a 7 to 10 degree turn so I don't have to stress the rubber to get it to seal.  Do you have any recommendations? So tomorrow, I will get non-wired hose.  I start road testing after that.  I am excited, it feels very strong on the bench, much different tone than the original motor</blockquote>
