1959 - McCulloch's Entry into Kart Racing

The McCulloch 10-10 automatic stricks me as the base model of the 10-10 series. I have McCulloch Pro Mac10-10, Pro 10-10, the 1-10 as well.All kinds of them. McCulloch Mac 10-10// technical data Your saw is 54 cubic centimeters and mine is 57 cc. I think it would be hard to tell the difference even if you had the saws together and were using them on the same log. You are talking about a 5 percent increase in engine volume.

Many of you already know that McCulloch officially entered into the kart racing engine business in 1959 with the introduction of the MC-10. The following is an article (slightly edited) that appeared in the Feb 1960 issue of 'Quarter Midget & Karting World' magazine. (The magazine transitioned later that year into 'Karting World', one of the most fondly remembered magazines from the early days of karting.) The article, which highlights the tribulations of Mac's early years in the business, is both historical and, in some ways, hysterical. Enough from me - here's the article - Bob.

Part I: Kart Engine Policy

The news filtering down through the karting grapevine across the country has confirmed what we have already seen with our own eyes. There is no question now that the McCulloch MC-10 engine clearly dominates the Super A and Super B classes. And already the rumor mill is bubbling over whether McCulloch will put out a similar engine for Modified A and perhaps other classes. These rumors stem from the many kart people who don't understand why McCulloch, in view of the success of the MC-10, doesn't quickly convert some of their other engine lines to kart use.

The old tank was cumbersome and restricted the air flow to the carburetor.

While this is an understandable assumption on the part of the karter, it nevertheless reflects only one side of the story. It would seem wise, in the interest of overall understanding, to give the manufacturer's view point as we understand it.

What the karter fails to realize is that while karting is a fast growing sport, it represents only a small drop in the McCulloch business bucket. Let's put it this way – McCulloch produces literally thousands of engines per month, only a small fraction of which is earmarked for karting. The bulk of McCulloch's business continues to be the production of chain saw engines.

Typical of any well established firm, McCulloch has a widespread network of wholesale distributors. Each distributor has a franchised territory in which he seta up a number of dealers to sell and service McCulloch chain saws. Each dealer, in turn, covers a specific area as determined by the amount of sales and service in that area. Bear in mind that this sales and service organization has been set up with the chain saw business in mind. Then – whoosh – along comes the advent of our our little karts and the rapid acceptance of McCulloch engines. This brings a new source of business for McCulloch Motors. While any new business is a blessing, this blessing, like many, comes with strings attached - problems of which the average karter is unaware. Let's look at how some of these problems came about and then speculate on their possible outcome.

One of the first changes early users (of the Mac chainsaw engine) made was to remove the transmission, clutch and recoil assembly.
The extra HP and reduced weight boosted this little kart to a quick win in its class. This second pic shows a McCulloch chain saw

At first, the karter adapted the complete saw unit (less, of course, blade and chain) to his little buzz-buggy. This was an expensive installation, but produced good results and the karter was happy. Happy, that is, until he ran into a McCulloch powered kart in which the chain saw unit had been stripped down to its essential component – the powerhead. Gone were the transmission, clutch and housing, and gone too the power loss from the gear train. This stripped down engine (indeed the forerunner of the MC-10) whipped everything in its class including the other McCullochs. The clamor immediately went up for the factory to produce and make available these powerhead units. To meet this demand almost overnight, the factory was faced with several immediate problems. A new carburetor adaptor had to be made (the old one was part of the gas tank) and the head, cooling shroud and fan housing had to be diverted from the '44' engine line. Different packaging had to be worked out, to say nothing of interrupting and changing the assembly lines to produce these units. The McCulloch people took these problems in stride and soon the MC-10's were being distributed to kart manufacturers. McCulloch's problems, however, had only just begun
