stumped

This is the engine for my build-off bike. The engine will not fire. I got one backfire with starting fluid and another one ignited fuel vapors coming from the tank cap (never had that happen before:doah:). Here's what I checked: 1. Spark--hurt when my hand got too close to the spark tester, so...

On CL in Richmond.

I'm asking for your help! I picked this up as part of another deal, but I cannot figure out who the manufacturer was. It may be a cobbled together Frankenbike, but I'd be happy to just find out who made the frame. Some knowns: 1979 Briggs 3HP 80202 / 0016-01 (code 79050201) Mounts for...

Hi everyone, I have a GX620K1 engine (QZB2, GCAD) the 2XXXXXX serial number I have been trying to figure out what a certain hole in the carb is for and im stumped. I can see the fuel inlet, bowl drain outlet, and then there is this spot at the top that had some cut off hose running to it. I...

someone mentioned it's a bird, i'm stumped

sooooo... I'm trying to figure out a way to my throttle cable to the Tecumseh carb I have. I was hoping someone else here has been through this in the past and can help me out. thanks for any help I get, Lyle

Been able to identify every mini I've had till this one, any guesses. I'm thinking at least one wheel and the seat may not be original and can't see any remaining original colors under the thick red paint.

Okay, I'm stumped. It's not for a mini, but I know you guys can help. I've got spark. It will run when I prime it (or on starting fluid), but it dies shortly after. I have cleaned the carb vigorously two times. There is no leak between the carb and block, and I know the main jet is clean because...

Anyone ever see this one?

what is she?? and whats it missing or wrong.

Anyone have a clue? :shrug:

Hi all, This little machine has no markings on it. It has front and rear drum brakes and all appears correct and original. The 3.5 Briggs dates to 1964. Any input would be helpful. Thanks:shrug:

Looks a bit like Arco, but only a single downtube up front. I don't know. A friend told me $20, I told him I'd think about it.

I'm in the middle of getting this old mini-bike going again. I have not a clue on the make or age? I've searched everywhere and looked at many photos with no luck. Any help would be appreciated. Thanks!

Have a late 60's early 70's 80300 series B&S with the 2-piece flo jet carb. Trying to get engine running but having trouble with carb. Have installed rebuild kit and new float. Problem is that when bowl is empty and I turn on fuel from tank the engine starts and runs until it appears to flood...

I've seen this bike but can't seem to find what it is right now.

I picked up this Rupp tonight. The guy I got it from said his dad worked at Rupp back in the day and he had a couple laying around from when he was a kid. He was not sure what model this was, but it did come with the 12" rims. To the best of my knowledge only the Black Widows came with those...

Scored this with two bearcat twisters...
