Thanks all for welcoming me to the forum. I just bought a new-to-me R190 dump truck for a pretty good deal and I have a few questions. It didn’t come with a title or plate on the driver’s door so I’m speculating is is from 1954. 1. The engine block has RD450 180755 stamped on it and cast with 215720-R2 on it. I think the engine may be a more modern vintage any thoughts on the year? Any idea where another info plate may be located on the old beast? 2. The carburetor has part no. 997007 R92. I’ve also attached a picture of it. Is this a single barrel carburetor? I was under the impression the RD450s had at least double bbls. 3. The starter is quite sluggish. The previous owner used a pry bar to help actuate it. The Delco Remy starter model number (113040?) isn’t coming up with google searches. Any thoughts on my model? Picture attached. My plan is to take it off and give it a good degreasing and see if that helps at all. thanks all in advance, Colorado Chemist

Folks, I am brand spanking new to the Red Power world, though Dad raised me up on an F12 that I could never crank start. That’s another story though. I just acquired a 52 Super C and need to ask for advice on several issues. 1. Fuel. I’ve read that ethanol laced, non-leaded gasoline can be harmful. Are there additives that ought to be added to today’s gasoline to reduce this problem? 2. In a similar vein, what type of motor oil would you folks recommend? 3. Similar question as to hydraulic fluid? Thinking out loud: I am going to rebuild the carburetor. I do not know the type since the carburetor appears to have been painted over by a previous owner. First step would be to disassemble the unit and clean it up. Then give it a try. If the tractor likes this, stop and go no further. Otherwise, rebuild the current carburetor with a good kit. Are there any suggestions as to which kit to use? (Dad used kerosene as a cleaning fluid. What do you folks use in today’s world?) If this fails, replace the carburetor. Again, recommendations as to which kit? Lots of questions on my part. However, any suggestions or recommendations will be greatly appreciated. Thanks!

Have what I think is a fuel problem in my 37 T20. Tore the carb apart to clean it and I happened to have some carb parts from my 38 parts machine nearby. For some reason I noticed the venturi's looked to have different sized openings. Sure enough, the carb venturi I was running has about a .010 bigger throat than the other. Makes me wonder which one is correct. Anybody know if there is a venturi dimension difference between a K5 on an F20, T20, and F30? If I do happen to somehow have an F30 venturi would there be any benefit to running it in my carb since I have the engine bored to 4"? All I have is a T20 parts book and that lists the venturi as 22838D.

Overhauling my mother's 544 AGAIN. This time we're at .060 over. I've never done anything with the carburetor, but it seems like it's time. Has anyone ever drilled the high speed jet in the carburetor to compensate for the larger bore? If so, how big did they make it?

Has anyone installed an overflow tube in the carb float bowl? Specifically for the Marvel Schebler TSX series, I'd be very interested in any info or tips on this from someone who has done it. The background - I've had an ongoing problem with flooding on my IH 444. I know I need to go over the whole fuel system, tank to inlet screen, to make it clean, but I figured this would be a useful backup. With an overflow tube, if the needle or float does get stuck, the gas would run out on the ground instead of into the intake manifold, stalling out the engine. (And trying to restart a flooded engine has resulted in ignition problems as well). I've done this on a motorcycle before, a Kawasaki Concours. Known for an occasional bent connecting rod from a combustion chamber full of liquid gasoline after the gas petcock went bad and the float valve also stuck. So it was a fairly common mod in the group of Concours owners, as insurance against engine damage. The basic idea is drilling out a hole in the bottom of the float bowl, and pressing in a brass tube. The top of the tube has to be higher than the normal fuel level. But on the Concours, I had instructions from someone who had done it and documented it. Very handy. So if someone has experience with this on a carb similar to what I have on my 444, I'd sure appreciate hearing from you! Keith

I have a 1949 farmall cub that I am having the toughest time getting any sort of throttle variance at the throttle control. I have adjusted the linkage, the carburetor Idle screw and the governor adjustments. I'm not looking to have a hot rod or anything but I do want to figure out how to have some control over the throttle. Does anybody have any tips or tricks on how to get a little bit better throttle control?
