issues

Are there any issues with mounting a torque convertor and interference with the rear mounted Briggs gas tank? Thanks!

So, I have a stock CT200U, and the kill switch stopped working. We did notice the green ground wire was not connected to anything at that time. I know someone that had experience in small engine repair, and he insisted that he could fix the kill switch. He removed wires and reconnected them, I...

Hi Gang. First post here. I hope you guys can help me out with this. I got a really great deal on two Coleman CT100U's which I bought for my kiddos through Walmart.com. The bikes arrived banged up and missing some parts, but that's a story for another time. I was able to get one running by...

I decided to put a HS50 on my Rupp R2 while I get the 10 HP vibration issues worked out. I partially freshened up a low use 50 I have cleaned and lapped the valves, put in new points, condenser, coil and carburetor, when I tried to start the 50 it was difficult to get going and when I dialed in...

Got both of my H60s running today (subjects of an earlier thread). Both have brand new H60 knock-off carbs. After running the solid state H60 back about a month and a half ago, I had way too much fuel even with both circuit screws barely open. So, I reset the floats on both carbs to be a bit...

Can someone confirm if this is correct on my SB. The throttle doesn't want to close if the move the lever that the cable pulls at all. If you move the lever far enough to close the carb the spring on the arm is totally free and not returning the arm any longer. In the pic you can see that the...

Hey Guys, We are having issues with the clearance with the brake caliper clearance on this build. We bought the Gigantic Kit from Bad Dog, so it included the caliper and everything but now once we have gotten everything close to assembled we are finding issues. Hoping that some folks in...

My el Tigre resto-mod project is coming along nicely. So far I have replaced the handle bar grips and throttle control, the rear shocks, the clutch, and added a clutch band brake. Additionally, any bolts that get touched get replaced with grade 8 fasteners. Lastly, I replaced the wheels with...

Could a defective CDI coil pack cause a lack of higher RPM's but other wise run fine at idle and slower RPM's? Something is not quite right with my Lawn Boy Duraforce 2 cycle engine that I have adapted for use on my Sprocket mini bike. The CDI coil pack high tension lead was pinched and I...

I bought a Heald Super Bronc a few weeks ago. It will start up just fine but won't stay idling unless you choke it when it tries to stall. You can keep it running as long as you bump the throttle. I have tried to purchase a new carburetor but guess what, they told me they quit manufacturing...

just curious as how well the work and hold up to a big block...

Hey guys, i am curious if yall could help me figure out all the different issues of popular mechanics that had minibike or cart builds or artictles. We all know about the Tom Thumb issue from Jan 1970 which i already have. I know there is at least one more issue with a build in it. Does anyone...

Hello all, I've been having quite a bit of issues with my rear sprocket. The rim and sprocket are a one piece assembly, and cannot be seperated. The tire size is a 4.10x3.50x6. The sprocket doesnt appear to be "true" and wobbles when rotating. At higher speeds i believe it is causing the chain...

Hey guys, I've recently been having a problem with my 212cc Predator. My bike starts up just fine and has no issues but when I switch it into run, the engine dies after about 5 seconds. The gas is on and I'm not really sure what would cause this to happen. The engine also is relatively new and...

Hello all, We have recently acquired a manco thunderbird that had been sitting for several years. I started it and it ran for three minutes before it wouldnt start again. It had about 40psi of compression. We took the head off, cleaned the valves piston and head, tried to start it again and...

I rebuilt the predator 212 that was smoking and had a little blow by, and it runs much much better, but there is always something that goes wrong. I bought a cheap carb off ebay and it ran too rich with the .37 jet so switch it out with a .35 now having a issue with the carb leaking down the...
