Another Carb Question...

[Deleted User]

I know that this subject has been talked about in past threads (I looked) but, on a 175 six, the maintenance manual states that 4 gaskets are stacked and used on the intake manifold, followed by the heat shield, a couple more gaskets and then the carb...



Was this done way back when to increase the carb height above the intake for some specific reason? I've heard it's to help with heat, rates of thermal expansion between dissimilar metals, but that doesn't make a lot of sense.



If the additional height is "just required" for obscure reason(s) could a spacer be used, and if so, how thick should it be and is aluminum OK?



Thanks

The gaskets are for heat insulation. Alloy is a good dissipator of heat, but it may dissipate it up into the carby. Stick to the gaskets.

I'll second that. Lee

I use 4 gaskets, then the shield, then 4 more gaskets. Had to put in new threaded studs of a greater length, to allow this, but I think it's worth it.

Craig-

To slightly change the subject, you mention a maintenance manual in your question. I have the 1941 Mechanical Procedure Manual as well as the part number manual, but these do not contain the detailed illustrations which I'd like to see. Do you have recommendations for other reference material, manuals or books which will help me with my '41? Any and all comments would be appreciated.

My 1942 - 47 Mechanical Procedures Manual illustrates 4 gaskets, 1 heat sheild, 4 more gaskets then the carb.



I do not know if the 1941 is any different.

Bill:



I found some Carter carb technical manual pages somewhere on the internet... I'll have to look and see if I have the site bookmarked. Someone on the forum may know the sites....



I do have copies of these pages that I cut and pasted in word... they cover some adjustments with exploded diagrams and instructions. PM me with your email and I'll send what I have to you
