Default Project minibike probs. PLEASE HELP

I have an old doodlebug minibike that I'm trying to get running. This is my first project minibike, and I've been through the whole engine. Everything looks fine. The kill switch has been cut. Will this cause it not to run? Also, seems like the brakes are locked up a little bit, it will roll but not good. Is there anything I can do to make the brake pad space larger? Thanks for the help.

Find the wire and ground it to the frame if it starts that's your problem sometimes it needs to be grounded others the ground is what kills it as for brakes adjust the tension at the lever move it to be seated with the lever if it still tight loosen the cable at the caliper and let about 1/8 inch of the wire slide through and tighten it down

Thanks for the brakes. The wire for kill switch has been completely cut. I have a parts bike, so I'll just take it off that one and put it on the good one.

The wire should be coming off of the magneto if I'm correct....think I am never really tore into any of the doodlebugs but I know I always have leaks in the intake manifold...think its called something else on small engines but its the rubber between the carb and engine every time I pulled the carb off to clean it had to replace gasket to

Alright. Spark plug wire was in bad shape so I tried pulling it off, and ripped off the magneto. Inside the magneto is there supposed to be a pointy thing? Sorry for my lack of knowledge.

Alright. Got it to where it would start on starting fluid, but when you stop spraying, it cuts off. Is this a dirty carb? I took it off and it was clean from what I could see.

Could be dirty run a twist tie with the plastic burnt off through your jets be sure to clean main and pilot jet...I think that's the only two or it could be a leak between the carb and engine either way its to lean that's why it runs on starter fluid cause it runs it rich

Great! cleaned the carb, and it runs like a charm! Another problem now. This thing is so hard to push, and it will barely move with no one on it. How do I make it roll freely?

If you got your brakes to not rub and its still doing that then u need to grease or replace the bearings in the wheel

I mentioned that in the first post but if they are still tight adjust the tension at the caliper all more....don't pull the wire through let some out and it will let the pad spread....I always loosen the bolt and let all tension off the pads then adjust the pad till they are just about seated to the disk then tighten the bolt....thinking about it you might have a bent disk does its grab all the way around on a full revolution or just certain parts

Thanks Poboy...
I was just about to post about this... Where it must be great to know all about stuff and don't need to explain to the rest of us here...
After all I'm just a guy who built all of his stuff and WTF does he know when he's asking for clarification... Pardon me....



Rant off....

With all due respect.. Slow your roll buddy...
I don't know off hand what a bug is and or what engine it's got, let alone brakes.
If I asked for more pics, that's just the obligatory post...
And no do I want to go google it to find out....


This happens alot of times here, we ask all people to help us help you when posting... I don't think that's too much to ask...

Look here Nick You 22 yr old little puke. This is not Facebook or U-tube, and your not commenting on some social media garbage you saw on MTV last night.
This is a G rated forum where adults and kids share info and learn about their projects. Your comments about Vibrating plugs up peoples behinds are not welcome here. Go back to junior high and find some friends, I bet a bunch a pimply faced 14yr olds would think you a really cool. But we do not.
