Hi Grant

Also referred to in old truck manual...civvy....Zenith 28 or 28-228 which is a rare bird according to the Oak boys.....

May need to check some CCKW sites for parts....

Don't know what other people are getting as suggested other videos but when I opened Test 1 I got a bunch of BBC Top Gear video clips so you are getting some high class similar video.

As to relocating the carb vent that sounds like the best answer. If you do it please post how to photos.

Now that you have started hill climbing I'll have to go looking for some steep grades. 261 in the C60S Beauty handles 6% highway grades in third gear 30 mph half throttle. So now I've got to find a straight on grade some good steep dirt tracks around here but most of them have turns in the hills so that backing down or stalling out could get really ugly.

Love the video.

Cheers Phil

Well all the still pictures did not turnout.....may have to do it again...

Sure feels steeper when you are lying with 60 of your body weight on the back rest..... now that I see the picturtes and it is not so steep.... next time I am shooting to go over the hill.

did not realize the back end roller was scrapping the ground going up the hill..

Carb does not seem to flow out until about 3/4 of the way up ...maybe over 35 to 40 degrees....... test backing up were not good since the frame gets hung up in the wood chips.....and wheels spin.

Good news Phil..... I can hold it up the hill and the oil pressure hardly changes...... starts at 42 psi drops to about 35 psi as I near the extreme angle..... apply brakes...let engine idle...pressure goes back up to about38/39 psi .....so not too bad..... gas leaks out and we can't find from where..
the vent hole on the Rochester is not apparent....

Good news is we found some source for Zenith 28-228 carburators.... brand new from California..... intended for single, double and triple carb manifolds... price to be determined.....

...other good news..... Grant recent acquisition of a C60X still has the 270 GMC engine..... and the original Zenith 28-228 carb......

Other possibility is a Weber 2 barrel carb intended for 4x4 extreme driving...designed for preventing fuel surge..... can be jetted for Willys, chev, etc....

On the venting issue Phil..... the carb shop in TO suggested plugging the original vent hole.... which we could not see.... and drilling a new hole with an extension rubber line above the carb..... not to sure I want to do that....

Final words of wisdom from fellow Rotter.... how often will you be driving at such an extreme angle....? Well you never know..... could be doing a parade in downtown Quebec city on the very steep hills and could stall the whole parade if I am not ready for it.....!!!!

Amazed at how easy the rollign chassis goes up a hilljust using fast idle setting.... maybe 850 rpm....

On the way back home.... on pavement.... easily shifted to 2nd, 3rd, 4th gear.... low range.... a nice feeling with no doors......

Those couple of filmings provided great entertainment.

Oh and hopefully some productive research.....

Great courage Bob!!! Geez the trucks can climb can't they??

Funny thing is the hill looks and feels a lot steeper from the driver's seat.

Will probably do it again for some still pictures...... that way I casn get close up or blow ups of pictures showing better where the gas is leaking form.....

Also thinking of fabricating some kind of pendalum device that will show the angle of attack and have it mounted near the carb so it will be in the picture and maybe we can capture the angle at which it starts leaking.

Major accomplishment today was moving a 20 foot sea container using the 3 point hitch on the 255 Massey.... very near it's limit for lifting...front bucket loaded with wet gravel helped balance the load. I fabricated a removable axle from 4 inch square tubing which wqe insertyed in the massive forklift pockets located at about 33 and 66 % of the container.

We lifted the sucker and positioned it on pressure treated bunks..... high enough off the ground that ramps will be needed BUT it will also allow up to open the door when we have that terrible white stuff on the ground. Thanks to Grant's help (muscle and brains) and advice on how to set it up and back up blinded by the container. Now the C15a is safely stored inside with enough space at the front that I will build some racks/shelving..... and locked with two padlocks.

Once in place the axle was removed and stored inside for whenever we get a second one.....spaced 20 feet apart with some sheet metal roofing we would gain covered parking for two more CMPs..... the removeable axle is a bit of a cobbled together piece of kit but worth it weight in gold if I was to call in a tow truck to move the container on a Sunday afternoon.

Thank God I can go to work at the office tomorrow and get some rest....and people do not understand why I am still working instead of retiring... it to rest from the darn fun weekend...
