I am wondering if anyone else has had problems with the choke on the Weber carb?

I had a heck of a time starting the machine but once I put a bag over the air filter it fired right up!!!

The choke lever fully engages but it doesnt seem to make a difference. Is there some sort of internal settings that I am missing?

hi, When you activate the choke you give it a little trottle this accuates a little cam on the choke circut. If this doesn't work you have to remove the carb. On the manifold side there is a choke cover carefully remove try not to damage the gasket, make sure all linkage is operating . The next thing is the accerreator pump circuit. When you open the throttle you should see a little squirt of gas in the venturi. You can go on weber website manual no. 95.0000.54 it was 19.00 its a great book lots of pictures and schematics breakdowns plus every tuning tip known on these carbs. If order anything it has all part numbers. I hope this helps Ghosthunter Will

I never hooked the choke up on mine. I turn the key on for a few seconds to let fuel pressure to come up, a couple pumps on the throttle, and it always starts right up. Might have to pump a couple more times to keep it running for 1st 15 seconds, but that's all. Good luck.

I took apart hte carb and for what I can see the choke actuates 2 little gears and they lift two little cylinders and beyond that it most do something internal.

So it seems to be functioning but still have troubles starting. As far as the accelerator pump it does squirt when the gas is pressed.

So I don't know what else could be causing it, I am thinking I am running rich but havent had time to tweak the jets would this cause the hard starting issues?

I bought the turbo and the difference is unbelievable night and day.

If you are running rich it would easy to load up the engine with making hard to start. Who's plugs are you running and what gap. What air cleaner are you running.

I got champion plugs with standard gap and K & N air filter!

I am blowing black smoke when running and the acceleration and deacceleration are not smooth it seems to miss.

But looking at my plugs I have carbon build up on the edges but the center of the plug is a brown color. I am getting mixed results, I only have a couple hours of riding with the new carb and am wondering if it is needing more break-in time to find its balance?

Sounds to me like your still alittle rich, plugs im running ngk be7s, some guys are running up to be9s even hotter, cross refference your champion and see how hot they are to mine. Im running 33 degrees total advance i think it will take more. Valve adjustment right im running .006 intake,.010 exhaust this has worked the best so far. I hope this helps Ghosthunter

Road bradshaw trail last week with sidexside guys out in places by myself and copilot,long straight way, could see way up trail,hit speed 76 miles per hour ,fourth gear 5200 on tach,buggy ran great.

if possible could someone who has a turbo'd joyner 650 please take a picture or tell me where they get the oil pick up from. I am researching into putting a turbo on my joyner 650 but refuse to pay the £2000 people over here in the UK are asking for them when the parts can be sourced individual for a lot less. i have just a couple of questions if anyone can answer them.

1. the plumbing of the oil return should be quite easy but where do you get the oil feed from, you can get an oil feed from an oil cooler sandwich plate between the filter but wondering if there was another place that would be easier and cheaper.
2. do you need to get a water cooled turbo and run an intercooler or is this optional do the kits use an intercooler im aware that using one would lower intake temps.
3. im aware of the need of an uprated fuel pump and pressure regulator but what fuel pressure is needed.
4. how about fuel enrichment for when the boost kicks in.
5. do you need to do anything abot the ignition timing as when i turbo'd my car a few years ago i had to install a timing retard system for when the boost kicked in.
6. does the standard carb work well with the turbo or do i need to rejet.
i know theres a lot there but any help would be welcome thank you.
