I read recently in another thread that minibike tires often exceed the size written on the tire. My Trail Bronc has 15.0 x 6.0-6 tire on the front. Does this mean a 145/70-6 knobby might be as tall or taller than the 15.0 x 6.0-6 on my trail Bronc? It seems to be the closest knobby in size to...

I just bought a bunch of small engine parts form a Craigslist ad. In the bunch was a new Oregon 50-647 carburetor. What Tecumseh engines will this work with? Mike T edit. Some forum searching and I found this carb replaces Tecumseh carb 632615. I found several threads here saying it would work...

This H70 Tecumseh that I bought came with a Mercury centrifugal clutch. Numbers on it are 5046-22 it's for a 3/4" shaft. The drum is really loose and floppy on the center. Are there service parts available for these somewhere? I searched the forums but found little information on the Mercury...

Today I answered A Craigslist ad for a 5HP Tecumseh engine. Pictures in the ad showed a white engine that looked like a Tecumseh. For the $20.00 asking price I wasn't arguing. It would be worth it for that kind of money just for parts. When I got to the guys place I checked the engine by pulling...

I was talking to my brother about the Ruttman that we got new when were kids. It has been identified here on this forum as a 1969 and that would figure because we got it during the summer of 1970 from a small local dealer selling out of his garage. My brother said it came bare steel and we...

While digging around in my minibike parts inventory I found this odd 5" wheel and tire. It is a 2 piece wheel but one half is steel while the other is aluminum. I decided to clean it up a bit and discovered the marks. Stamped into the aluminum wheel is 1034-2 with a "O" beneath it. The steel...

What gauge metal was used for the long chain guard on the Sears Drover? Also is there a source for the cool SR decal that looks like a stylized Atom? Mike T

A few weeks ago I started collecting the last items I needed to complete this Drover frame I have had for a few decades into a running minibike. Last summer I found a Craftsman 3.5 horse side popper that runs excellent and I'm going to use that on this build. I am not going to attempts a 100...

I am starting to work on this minibike that I have had for decades. It is little more than a frame but pretty solid. I think it's a Sears Drover. The bottom layer of paint is a limey green. I have more pictures if additional detail is needed. I want to stay fairly close to original when I build...

This is my first real Minibike build. I've fixed up a few and done mechanical work etc, but never a “frame up” build before. I've done Volkswagens, Chevys, I'm doing a dune buggy now. But I just got an itch to do this bike. So here goes... This little mini has been stashed around my shop for...

I am disassembling this little Ruttman my family has owned since new and when I took the rear wheel and sprocket apart I found what looked like gasket material between the wheel halves. It was in real bad shape, crumbling, broken and falling apart. The front didn't seem to have anything like...

I wanted to introduce myself here. I have been a member for 3 years but really am not much of a poster. I mostly read and search for what I want to find out. I like that there are so many knowledgeable guys on this forum and I will be relying on that knowledge during the builds I have planned...
