Great minds think alike, I was thinking the same ,How about using hardwood shims that can be swapped out to fine tune incidence?

If it helps, we (my and I) run one tank on the four cylinder motors with two carbs. 5/16" Tygon from klunk to "T". 1/8" Tygon from "T" to each carb. Superb in fuel delivery and sets up like any normally plumbed twin or single. Not sure the 5/16" is necessary, but we've not had any problems.Yes the 300 has twin carbs, but what if simply two gas line with one tank, what do you think?
yes I was leaning towards doing this also, tell me the Tygon you use , which is what I use also, does it harden a lot, mine does. and of course the worry is for the clunk in the tankIf it helps, we (my and I) run one tank on the four cylinder motors with two carbs. 5/16" Tygon from klunk to "T". 1/8" Tygon from "T" to each carb.

There have been reports of the Tygon "stiffening" after 6 months to a year. However everyone I know that has Tygon fuel line that gets hard, is using Ethanol fuel. We, ( my son, friends and myself) all use 91 Octane non ethanol premium. Fuel lines on my 260 are now well into their 4th season. Most my other planes have 1, 2 or 3 years on them. Same fuel line with no stiffening at all. My sons 222 and lil Pilot Yak are doing great too.yes I was leaning towards doing this also, tell me the Tygon you use , which is what I use also, does it harden a lot, mine does. and of course the worry is for the clunk in the tank
interesting observation, I can easily get gasoline without ethanol here in New BrunswickThere have been reports of the Tygon "stiffening" after 6 months to a year.

another interesting alternative, thanks guys really appreciate all the good adviceUse Viton tubing for your clunk lines....never hardens regardless of fuel. See good ole McMaster Carr

I use the high temp soft Viton.
