I can't find the part number for the plugs on cylinders 1, 2 and 4.

Can anyone help?
Cheers,

Should find them at your local bolt stockist,

Cheers as always Dave- I had a feeling you might be the man with the answer!
I'll only need 3 washers then as I'm not replacing the vacuum spigot?

As they're screws I assume they're not torqued up, just hand tightened?

[arsey30]

Tighten normally with a long cross head screwdriver. [JIS if OEM]

I find cap head [allen ] screws easier to fit, using a 3/8" or 1/4" ball end socket drive extension.

I'm planning on getting an auxiliary fuel tank to balance the carbs and I assume it won't have a fixture for the vacuum tube from cylinder 3. Will gravity be sufficient to get fuel flowing properly?

[arsey30]

The tap only works on gravity any way, the vacuum does not suck the fuel through, it just opens the tap outlet
You won't need vacuum feed on your temp tank, but blank the hose with a dowel or plug to stop it drawing air.

A Honda 50 tank is good, has a tap and filter. Its standard hose should push fit inside yours

Awesome. You've answered my next question which was going to be about sealing the vacuum hose. This way is actually easier because I won't have to remove it at the cylinder inlet (which is a PITA to get to) as I'll seal and clamp it at the other end.

Any chance of a link to a Honda 50 tank?

Honda 50 tanks are getting rare but any old small tank with a tap will do.
Even a lawn mower one

I think either of these will suffice?

Either is just the job.
