Default Important reminder regarding carb installation

Last week I received an email from a customer who'd just purchased a rather expensive carb from me. To make a long story short, while following <span style="font-weight: bold"><span style="text-decoration: underline">erroneous</span></span> information in his factory service manual, he had the misfortune of snapping an ear off the base plate.

Turns out his manual stated that the carb mounting fasteners were supposed to be torqued down to <span style="font-style: italic">15 lb.ft.!</span> [img]<<GRAEMLIN_URL>>/eek.gif[/img]

I don't care what any service manuals state, this is a fast track path to a busted baseplate and/or a warped carb. The customer simply didn't know any better and was <span style="font-style: italic">trying</span> to follow proper procedure, so he bears no blame here.

1/4&quot; carb mounting fasteners should be torqued to 60-80 <span style="font-weight: bold"><span style="text-decoration: underline">inch</span></span> lbs., or roughly 5-6 lb.ft. In layman's terms, about as tight as you can get them with a plain nut driver (<span style="font-weight: bold">NOT</span> a ratchet!).

So spare yourself, your carburetor...and your wallet from unnecessary heartache. Leave the ratchet in the toolbox when installing your carb. If you simply <span style="font-style: italic">must</span> use a ratchet, use a 1/4&quot; drive.

Eric -- another SNAFU back in the day were these &quot;layered&quot; insulation plates. IE: Gasket, alum plate, gasket, alum plate, etc. about 5 or 6 thicknesses. Result? Warped/broken plate!! TAZ
