carbs

My new 70 Bug currently has a 31 pict carb on it, but it doesn't look like it will work. I have a line on a 34 Pict-3, so I was going to put that on. Would there be any issues coming from that, or would it not be affected at all?

If it is a dual port.. should not have any problems. If you have a single port.. you might need a 1" carb riser to clear the generator. I just had this problem 2 days ago. I have the 30 pict 3 on my 1600 single port. The accelerator pump was against the geni ground bolt so it would not work. I just put the riser on yesterday and it runs smooth as silk now. The 30 pict 3 was the first carb for the dual port.
I don't know much about a 34 pict 3.. the 34 pict 4 is a pain in the butt if you use a mechanical 009 distributor. I have never heard of a 31 pict carb at all. From my understanding it went from 30 pict 3 to the 34 picts. Also I believe there is an adapter you can get for the 34-pict 4 to fit the single port manifold.

But all in all, it should work with or without an adapter.

OK Thanks, and it might be a 30, I was just looking through all the grime on it, and thought it was 31. I'll double check just for fun.

re-checked it, 30 pict 1.

Pict 34 will work well with an 009 distributor, but only if you solder up the air hole in the butterfly. I've done mine, and it works great! Here's a link that you might find helpful.

Good to know, thanks.
