Lastly for now, I'm guessing with a Uni Mount or Robron engine mount and then the McCulloch and/or West Bend engines each have a unique mount to use with the Uni Mount or Robron mount? does the axle setup look original to this kart? Does the brake rotor/setup and rear sprocket setup look original for this kart? The axle is a 1" diameter measured at the center. Now, to the brake and the rear sprocket (see pics). Additionally, is it feasible to run a 10" tall tire on the front and 11" tall tire on the rears? I see some 11" and 12" tall tires that fit a 5" rim. I would like a little more ground clearance. Looks like the tires are supposed to be 3.5" or 4" wide? The ones on the kart now are 4.5" wide and I'm having a problem with the right side tire rubbing on the spindle arm. I like the idea of returning to vintage style tires. So, are these Lancer karts supposed to be orange? Period correct sounds like a good plan to me! I restored an old Harley 10 years ago and finding the correct parts was a real challenge! I'm trying to learn what I have as a kart and what I can do with it. Thanks Chris and Ted for the information and advice. Worry less about having the kart "Rupp Original", and more about having it period correct. I have both brands of clutch on my two West Bend equipped karts. The Rev Grip is harder to find, but simpler to fiddle with. Either one of Jim Donovan's latest Max Torque clutches, or a vintage Horstman Rev Grip will work very well and be easy to deal with. You can make an 820 as fast as you can handle.
Rupp go kart frame mac#
A Mac 91 is a great way to go engine wise, but the 820 West Bend/Chrysler/US Marine/US Motor power engine is infinitely easier to work on, and most parts are currently available. Remember that it is a failure waiting to happen if you use a master link in your chain. The main reason for switching the engine to the right side of the kart is that it's much easier dealing with sprocket and chain if they're outboard of the frame. As far as the engine mount goes, Robron will have a swing mount that should work on a Rupp kart without the expenditure of a Uni Mount. Vintage Speed or Cheng Shin tires both work very well. Ted, I'd switch to vintage tires and leave the Nylite style wheels on the Lancer. Thanks again for any and all information and advice. Is the chrome rear frame OEM or was it chromed? See attached picture, I'm guessing the kart currently has some kind of backyard built engine mount? If I went with a single McCulloch 80cc engine what could I expect for performance and top speed?Īlso, I've been looking at examples of OEM McCulloch engine mounts. Probably easy fix, but why? However, I did get it running temporarily and it did run 45 MPH on GPS and was still pulling when I ran out of straightaway. Carb is messed up, pulse pump doesn't work right. I'm a sucker for this kind of stuff!Ĭlone engine has some issues. I didn't want to see a piece of history go that way. Kart was being turned into a kid's street/yard kart. So, I'm probably going to disassemble the kart and start looking for parts to return it to stock form. However, I'll probably have snow on the ground in a couple of weeks. I'm lucky, I have a large asphalt area next to my shop where I can run it.
