Good Morning,
I am working on a super bronc, and would like to add a light. I purchased some LED headlights off amazon. They were ten bucks a piece, and look to be OK quality. I disassembled the units and sealed them with silicon as the reviews were said that was an issue. If I purchase a...
I just made two the other night. What I ended up using was a heavier gauge electric fence wire. It was stiff enough not to bend, but thin enough to get good bends. A couple pair of vice grips and wala.
Throttle Situation
Here is the throttle set-up from the original HM80 that was factory:
Here is the factory throttle set-up from the new engine:
Here is what I came up with:
Note: There was a cable stop on the throttle cable. I removed it for clarity.
If anyone has any ideas...
I think the problem is the governor. Engine off: Twist throttle and it will open the throttle to 100%. Engine off, the spring isn't strong enough to open past 15%. I can hit the throttle linkage by hand and it roars to life. I was messing with it last night, and after burning my hand on the...
Got almost everything installed last night. The only issue I am having is the throttle. I cannot seem to get the throttle to wide open. I am hoping maybe tonight will be the night!
I took the measurements prior to ordering. I THINK I ordered the right belt. The distance was 7.625" center to center.
And if the chain will not function as intended, I can run to the local farm and fleet and pick up a section.
Thanks for all the input. I can't wait to get the parts needed...
I am probably wrong, but won't the 420 chain work on 40/41 gears? I thought it was a slightly stronger chain option? The order has already been shipped.

Hey Mark,
Thanks. I think it turned out well. The tires are 22x11x8. I was in the process of trying to get the rear bead seated, so it was over inflated. The tires are the same size. And I got them at the local fleet farm. Also, the seat is original.
I live near Menomonie. You?
Roccosbike,
Thanks for the reply. I have the old engine sitting in a box with all the parts. Right now, I am just looking for a bolt on replacement. I am in the middle of a frame off restoration on an old Jeep, and would rather keep the time spent working on the Super Bronc to a minimum.

Good Morning OldMiniBikes,
I am in the final stages of restoring a Heald Super Bronc that was my Grandpa's Uncle's ice fishing machine. I received this unit in non-functioning condition. The screw that attached the choke butterfly to the shaft let loose, and both the screw and butterfly was taken...
I have a new Honda GX390 horizontal shaft electric start engine. I was going to mount it on a go cart, but have recently purchased a CJ-5 so my little toys are getting sold. I have the owners manual, factory tools, and some other misc. paper work. I mounted a clutch on the shaft for fit up, but...
What about this valve cover?
I am trying to determine if i have a Hemi or not. I looked at the pictures on OldMiniBikes warehouse, but my cover does not match the ones shown. Any help would be appreciated.
