83 CR500, here begineth the lesson

About ten kicks and ran as many seconds. Had just knocked the choke of at kick 4. It sounded good but then died.

the goat got away! im sorry! try again.

Get its spleen out and soak it in vinegar before splicing it and disecting and reporting back.

10 kicks

Take heart, I've seen worse. Good luck, and keep us all posted.

Hmm, could this be a clue ?

Yup.

Possibly need a new petcock and new needle/seat kit for the carb. Some folks just disconnect the fuel line and clamp it off when the bikes not being run. I like new parts though...

Yep. Been there, filled the carb, reeds, crankcase, and bottom of exhaust before dribbling out all over the floor !
New needle and seat and a new fuel tap (with reserve) cured it though.

I spoke to Allens performance and they will do a brand new carb for £115. I think as this bike is a keeper I might do this anyway as I know the slide is worn at the very least on the old one.
That sounds like a really good price and they have them on the shelf.
Just have to find the standard 430 jets and needle. I know the info is on here somewhere or might start a thread on the main page .

Mikuni jets dont wear like Bing jets, just transfer the ones out of the carb you have into the new one.

Thanks, I'll look at the price for all new as well though as they have been butchered a bit, both crossheads and hexheads.
Had a major panic about crank seals failing causing crankcase filling (ie no crankcase compression for transfer) but bubbled gearbox breather in a glass of water while using kickstartand looked at generator side and they look fine so hopefully carb related.

Did you clear out the crank case cavity after your first attempt several weeks ago? Was wondering if you had a large pool that evaporated leaving a bunch of oil behind to mix with the new gas from your attempt on Tuesday as the gas you sucked out looked awfully dark and grimmy.

Yes I think that was a lot to do with it. I used molykote as well in places so that may have made it so mucky. I'm going to flush it out a few times with gas from the tank and then leave it for a while with the reed blocks out.

I flooded the crap out of the 400 a few weeks a go and after 10 or more kicks on full throttle she blubbed into life and shot raw fuel out of the exhaust port manifold, the muffler join and the muffler. what a mess! My great needle and seat suddenly failed. so its fuel tap off from now on.

What is worth looking at is your float level before you go buying carbs. Your bike looks like it is well flooding your crank cases, I have had the same problem before and when I was told the bike was getting flooded I thought just a thimble full was over wetting the plug, I didnt realise you can get about a pint into the crank cases. Anyway this youtube video might help. It looks like your floats arnt cutting off your fuel supply when your bowl is full ( I may be wrong, but it worked for me)

you will need to empty your cases first before retrying. Hope it works.

Thanks V.R I will look at that, not now as cooking curry and draining Aussie wine lake. Was talking to someone about measuring the level with an adapted plug in the bottom of float bowl and a see through tube up the side of the carb to measure float height. Hope to get back to it tomorrow sometime, not ordered new carb but probably will sometime anyway, its been abused by MX riders for 30 years trying to change jets with rocks they found in they're tires (OK stereotypical but true of 80's MXers ! (?))

No no no no no no no no

Also remember, you can bend a rod trying to force an engine to turn over with a crankcase full of fuel. Good move to get it out with that syringe instead of trying to force it over.
