trouble starting my 05 zuma 50

05zuma · 05-10-2014, 11:30 PM

My 05 Zuma 50 and almost every time I try to start it I have to squirt startin fluid in spark plug hole or carb for it to start and then I drive it around turn it off and then it will start I guess after it warmed up and then let it sit a let it cool off then got to start with either any idea and I just replaced top end so has plenty of compression

If you're sure that a ring didn't get broken upon reassembly(it happens). I'd check to make sure the carb is clean, jets as well, also make sure intake boot is sealing well against jug and has no cracks, make sure carb. is installed all the way in the intake boot.

Ring did not get broken I am sure of that first off I have put 60 miles on it and it would not of lasted that long and carb is spotless and yes carberator is in boot and intake is on tight and has no cracks

I would put your hand across the air box or carb opening and see if it starts then. It sounds like a balky choke. Spraying ether is a pseudo choke.

That's what I thought and I have an extra carberator to if that doesn't work should I put that on it

Make sure your pilot jet isn't clogged. Also check your idle speed screw.

05zuma · 05-12-2014, 07:31 PM

They ain't clogged checked them multiple times and is there any way I can buy a manual choke for the thing I hate electric ones

Firehawk989 · 05-12-2014, 07:36 PM

You could get yourself a 17.5mm Dellorto Carb with a manual choke. Then if you upgrade to a 70 kit you won't have to do the carb as well. They're like 80 bucks or something though.

05zuma · 05-14-2014, 03:38 PM

That ain't to bad where can I find one and will it gain me any speed?oh and now it will only run if I put my hand on the carb where air box goes and then when I punch the gas pivot my hand out a little for more air it will run fine like that but take my hand off and it runs for a few seconds and then dies unless I put my hand back over the carb

How much compression does it have?
Does it help if you squirt a lil oil in the cylinder before you start it?
Oil pump working?

05zuma · 05-14-2014, 09:22 PM

I just rebuilt it and I mix my gas and oil 32:1 better smoke than choke

Firehawk989 · 05-15-2014, 02:31 AM

It won't run right without the airbox. Don't mess with the airbox until you go 70cc, then you can take out that rubber intake snorkel. Anything else you do will mess up how it runs.

05zuma · 05-15-2014, 09:02 PM

Won't run at all with the air box had to get the rubber air box pipe and then cap it and put a hole in it the size of my pinkie then I can stick my finger over the hole to start it then I can drive it 10 mph cause then it ain't getting anuf air so I'm stuck

Firehawk989 · 05-22-2014, 01:27 AM

Check compression and autochoke functionality. Is the plug wet/fouled? Also make sure the fuel petcock is working properly. Really sounds like something is clogged somewhere.

Well I just bought a carb choke was screwed up so bought a deltoro 17.5 carb with manual choke
