Single 46 carb for 760?

[beachedflunkey]

I'm assembling a motor from some parts lying around. I have a big bore 61x 760 with a mild groupk race port on a clearanced 62t bottom. I have a single 46 blackjack carb but no intake manifold yet. Might this setup work okay together with a bpipe?

The alternative would be to convert two single 44's to duals because I have everything I need except linkage but I've heard it can be a bitch to tune unmatched 44's :dunno:

I'm temporarily running a 46 mikuni on a big bore flat top with the ATP manifold and it runs awesome. My full spec should be here next week, but it runs pretty good as is.

I am trying to get a similar setup going with single 48 Full Spec

I've run that carb on an 86 mm ported motor on x cases. it's great.

Finally got the jetting nailed down. :arms:

It rips!

Now to work out this damn intermittent sudden stop.

Good info thanks! So anyone got a single intake for a 62t? :biggrin:

Hope the intermitant stop isnt ar WOT Mat.

He...I thought of that too. I don't think it's a seizure. It happens anywhere from 40%-100% throttle. My guess is a fuel flow problem.

However, I'll do a compression check.

Just a thought Matt, are you running a restrictor in the return line on that Full Spectrum?

Got it fixed. Chalk it up to user stupidity. Before I took it out on Saturday, I Had finally put a gas cap on the tank. I cut the hole with a dremel, and used a sanding drum to clean it up.
I thought I had done a decent job of cleaning the tank afterwards, but I was mistaken.
The fuel filter was plugged.
I changed the fuel filter and removed the long hose from the fuel pickup to get gas off the top. (Too lazy to drain the tank yet)
I took it out again yesterday, and it runs like a charm. :biggthumpup:
I still had a couple of shutdowns, but that was to be expected.

I just got done cleaning the tank out again, Should be good now.
I am really tempted to try dual 48 full spectrums since I have them. But I am very happy with the way it hits now, I'll probably just leave it the hell alone.
