CARBURETOR INSTRUCTION SHEET MODELS 4165 & 4175 - Holley
CARBURETOR INSTRUCTION SHEETMODELS 4165 & 4175READ THIS FIRST:This is a typical view type instruction sheet for different carburetor models, which will show more parts than are required for anyone specific model. This kit may also contain universal part assortments resulting in throw away, or an excess in the number ofparts that are actually required for servicing any one carburetor. In the case of duplicate gaskets or parts, compare with oldpieces. When reassembling the carburetor use the adjustment specifications list to make the necessary adjustments for the listnumber of your carburetor. Since this instruction sheet cannot contain all the pertinent information required to rebuild yourcarburetor, Holley recommends the HOLLEY - REBUILDING AND MODIFYING book by Jeff William’s P/N 36-185.Through out this instruction sheet there will be WARNINGS and NOTES, Please read these, they contain valuable informationthat can save you time and money.

Should you need information of parts assistance, please contact our technical servicedepartment at 1-270-781-9741, Monday through Friday, 7 a.m. to 5 p.m. CST. Please have the part number of the product youpurchased when you call.LOCATING THE LIST NUMBER:The List number for a Model 2010, 2300, 4010, 4011, 4150, 4160, 4165 or 4175 carburetor can be found on the right side ofchoke air horn. The List number for the 4500 can be found on the top of the main body casting. Below the list number is adate code that will contain no more than four (4) digits. See Figure 1 below.Figure 1DISASSEMBLY:Rest the carburetor on a repair stand to avoid damage to the throttle plates during the renew procedures. Use the explodedview, for the model of carburetor you have, as a guide and follow the numerical sequence in general to disassemble unit farenough to permit cleaning and inspection. DO NOT remove throttle plates or shaft. Idle limiter: turn the idle limiter cap to itsleanest (clockwise) position and remove cap. Observe and Record the initial position of the needle slot. Turn the idle needlesclockwise until lightly seated, recording the number of turns required to seat the needles. This procedure is necessary toreinstall the idle needles after renewing the carburetor.WARNING!Use care not to damage idle adjusting needles when removing idle limiter caps.CLEANING AND CARE:Cleaning must be done with carburetor disassembled. Soak parts long enough to soften and remove all foreign material. Use acarburetor solvent, lacquer thinner, or denatured alcohol. Make certain the throttle body is free of all hard carbon deposits.Wash off in suitable solvent. Blow all passages in castings with compress air and check carefully to insure thorough cleaning ofobscure areas.WARNING!DO NOT soak parts containing rubber or plastic material. Serious damage could result.WARNING!Fuel bowls, should only be exposed to carburetor cleaner long enough to permit removal of gum andvarnish deposits with a brush. Some fuel bowls have internal “O” Ring seals, which are not removable,but can be damaged by prolonged exposure to some carburetor cleaning solvents.REASSEMBLY:Reassemble in reverse order of disassembly. Note the special instructions and follow the calibration numbers in theSPECIFICATIONS manual in making final adjustments.Manually operate the throttle lever and choke mechanism, checking for binding or malfunction. Any binding or interferencecould cause throttle to stick during operation and result in loss of carburetor throttle control (or uncontrolled engine speed).WARNING!Check carburetor to be sure there are no leaks, flooding, which might cause a fire.1
SPECIAL INSTRUCTIONS FOR ALL CARBURETORS:IDLE ADJUSTING NEEDLES - Tapered portion of needle must be straight and smooth. If grooved or ridged, a new needle would be install.PUMP INLET CHECK VALVE - Lubricate tip of new valve and insert in center hole in pump cavity. Pull through from fuel bowl side untilseated.CHOKE PLATE SCREW - Choke plate screws are staked to prevent loosening. To avoid breaking or stripping the threads in the choke shaft,lightly file off the staking. Choke plate screws should be restaked after tightening to prevent loosening.THROTTLE BODY - DO NOT remove throttle shafts or plates. If throttle plates are nicked or damaged, it will be necessary to replace thethrottle body.CHECK BALL - Your kit may contain more than one check ball. The check ball removed from your carburetor should be compared to the newcheck ball for correct sizing before installation.Figure 2MODELS 4165 and 4175List Number6210, 6211, 6212, 6263, 6262, 6263, 64686210-1, -2, -3, 6211-1, 6468-1, -2, 6854,8679, 870064996497, 70546498, 6772, 677365286774, 6853, 7002-1, 7004-1, 7005-1,7006-1, -2, 8302, 85466926, 6926-1, 7002, 7004, 7005, 700670017351739778558059, 8059-1827688799895, 80073, 80125, 80139, 80140, 8015599239948, 9976, 8012880130-2Prim.
