Carbs: The most unrealistic part on every model car I've had


Recommended Posts

.. carburetors!! I never understood why these are cast so plain when I can read the numbers on speedometers. I can't think of any other part that is so badly done.

Do they expect they will all be covered by a massive air filter?


I have seen some aftermarket carbs that ARE nicely done .. so why can't the model car makers do the same?


Sorry about this .. was just looking thru kit boxes on a carb hunt recently .. I didn't win.

Seems like there were a couple from kits I had in the '90's that had decent carbs on them. I think it was the "Heavy Chevy" '70 Chevelle and a Pro Stock '57 Chevy also had some decent ones on it. I like not putting the breathers on those, Or just left it unglued, I'm with ya man!

Of course, the answer depends totally on which particular model(s) you're talking about. Some parts are done very well on one model, terribly on another.

As far as how many models are affected, I'd say unrealistically flat interior panels. Most cars, especially those older than the 80s, had window cranks, interior door handles, door lock pins, etc. that stood out from the surface. How many times have you seen a model with the interior panel details just sort of hinted at... or ignored altogether. It's especially obvious on convertibles, where the interior is the first thing you notice.

I'd have to go with carburetors also. Even in larger scales they are blobs at best. The Webers in the Accurate Miniatures Grad Sport Corvettes are mighty fine. With the Edelbrock AFB and AVS series carburetors being so popular one might think they're would be something nice in a kit.carb_0.jpgOf course the ever popular Holley 3310 would be another, How hard can this be ?

The Rochester Qudrajet and Carter Thermoquad usually turn out to be blobs too.

What an interesting question. In my case, I would say kit distributors.

Yeah, but some are done pretty well so you can even drill them out for wires. Even most of the wired ones in the aftermarket just have one big hole stuffed with wires ... excepting Morgan Automotive and Replicas and Miniatures.

This is more a function of how the interior was molded. The one piece interiors are definitely lacking in side panel detail .. or they wouldn't come out of the mold. The ones with separate sides are pretty nice as a whole.

I know they can't cast something like this accurately without four part sliding molds, but a few of those bumps would be nice.

Always loved the metal axles passing through the engine block and/or oil pan on the older AMT and MPC kits. How unrealistic is that?

Harry, I would agree with you, to a point: Vitually all model car kits tooled prior to say, the early 1980's were done with "tub-style" interior units--not all that odd considering that until the "revival" of the hobby and the industry in the 1980's, the expected market for model car kits was who? Answer: Kids.

With a "tub" style interior "bucket", it's impossible to engrave high-relief details on the sidewalls, and get the part to come free of the tooling in demolding, and that is fact.

That said, as early as 1957, Revell's 1957 Ford Country Squire station wagon kit had a true "platform-style" interior, the floor of which was the floor pan molded en-bloc with the frame, with carpet and floor mat detail on the upper side; separate interior panels AND a separate inner panel for the lower tailgate, with quite nicely done raised details (door handles, window cranks, vent wing cranks, even the latch details for the inner tailgate panel. So, the knowledge of how to do well detailed interiors existed 55-yrs ago, well before the rather young model car builders we were back then were really capable (or desireous!) of handling more complex projects. Of course, also well to consider is that from 1958 (the first AMT 3in1 Annual Series customizing kits), kits of a given year's new cars were based on promotional models made for the auto industry, and as such had to be designed for rather rapid mass-production assembly lines, and that meant a lot of simplification--hence "interior tubs". This carried on with such as the first AMT Trophy Series kits, again made for the expected market, the (approximately) 10-16 yr old kid hooked on model cars.

However, with the recognition on the part of the model kit industry (lead in the US by Monogram) in the early 1980's, that a huge demographic shift was well underway, the "10-16 year old kid" suddenly having morphed to men in their 30's and older; it was time to rethink interior detailing in the design process--enter the return of the "platform" interior setup as pioneered way back in '57 with that Country Squire.

As for carburetors, if one looks at any real carburetor, there are raised details, and intricate linkages that are a part of every one of them, going all the way back to the beginnings of the automobile. Now, in order to create raised details on all 4 sides of a miniature carburetor, that will necessarily require tooling that will reproduce that, and that means tooling that will slide together, then slide apart, every cycle, in order to produce that carburetor. Think of it this way: Virtually EVERY one-piece model car body shell requires a mold with SIX sides (if you think about it, any cardboard shipping box has SIX sides: Right side, left side, front side, rear side, top side and bottom side. It's that way with a model car body, my friend: Right side, left side, front end, rear end, upper surfaces, and the core mold that makes the inner surfaces. To do a small part such as a carburetor in this fashion, the same would be true, especially if one expects a detailed carburetor throat along with all the proper detailing on each face of that carburetor. Now, what if the model kit has multiple carbs (think Chevy or Pontiac Tri-Power setups here), that's a total of 18 moveable steel sliding mold cores! Now, how much are modelers willing to pay for all that? Hmmmm? And I haven't even addressed the intricacies of assembling such tiny plastic parts (Surely many here remember the carping about the overly intricate Trumpeter '60 Bonnevilles, the equally intricate Accurate Miniatures kits, no? Please note that I've not even addressed the really intricate parts of a carburetor--the linkages! Even if done in PE, those would intimidate a large majority of modelers, on two fronts: Extreme intricacy, and cost--that stuff ain't cheap folks!

The bottom line here is simply that some things which limited real surface detailing in the past (interior tubs) were actually pretty correct reads of the model kit consumer marketplace as it existed in decades past, while some of the limitations of what model companies are going to tool up today are those more related to costs VS returns.

Yeah, I know.

I wasn't talking about molding technology or its limitations. I just answered the question posed by Mike... What's the most unrealistic part of most models.

Glass! They always appear to be a scale 4" thick. Not to mention that most automotive glass has some grade of tint to it, not that easy to do for some of us.

In the future, I hope to mark that 4" edge with a black Sharpie. Even older cars without that black border appear to have "shadow" around where the glass meets the trim.

Six sides ? Sliding molds ? Aside from the body are there any other parts made this way ? How about a simple carburetor body ( not unlike a real 1:1 carb) with the detail parts molded separately ( linkage,choke,base plate)? Remember the adage, build each system (part) as a separate model unto it's self. Just as now, we can still add some of the detail our selves,( return springs,etc).

i think the less molded on, the easier it is to add
