Good prices for accessories - easy air cleaner as well

[Uncle-Pekka]

Reg Evans gave me this link some weeks ago. Lots of nice repro & aftermarket stuff in there - I will surely place an order there before Xmas.

However, when browsing all categories, I also found inexpensive chrome dome style air cleaners, many styles:

In my D24 I am happy to use the original oil bath unit, but on my Nash I've had tedious vapor lock & over flooding problems etc. which force me to take the air cleaner off several times a day. In those conditions the oil bath is not convenient. Big, bulgy and spills oil if it falls on side.

I've also seen lots of discussion here at p15-d24 to convert oil bath for paper filter. Much easier to mount one of these, starting from $9.

I will buy one for me Nash... Well should I take 2 just in case someday would find an Offy-head for two carb setup... Racing style-Unkka...

Pekka, depending on how small the aftermarket air filter is, you might

need to stack two or three of them to get adequate air flow.

I believe Mr Coatney could speak to that topic.

[Uncle-Pekka]

Rats!

I did not think of that at all.

Just ASSumed the flow would be enought since they are designed for standard single barrel 2 5/16" throat unit ...

I think I've seen these mounted on carbs feeding flathead engines, but it may be I've only seen these on two carburetor set ups - then the flow per unit would be half cmpred to mine std one unit system - right?

Please Don - tell us your experiences.

I found that when using a single small filter on my dual carburetor setup that my plugs would foul due to low air flow. I doubled up and have had no more problems.

Don,

What is the outer diameter & height of those filters (each)?

Were there any symptoms before the plugs failed?

[Don Coatney]

Speedway part number 910-11014

Yup, that's very same size as in the dome offered at Wirths', round 4" diameter.

I.e. won't work for our flattie... too bad. Would have looked good on her.

Found a simple calculator for air cleaner size in the web;

http://www.thedirtforum.com/airfilterheight.htm

Acc. to this calculation two diam.4" x height 2" paper filters should be enough for 230cid engine turning 3600 rpm.

Two choices brushed or polished.

Thanks - I know there are lots of choices of models & suppliers.

As said above, I will rely on original oil bath cleaner in long run.

That is the best system for a flathead both in resp of flow and air quality.

However, I considered the inexpensive small wirths cleaner as a temporary aid before I find all the right tuning of carb and ignition...

Now I become interested in the issues affecting to dimensioning the sufficient cleaner screen. Of course one can mount a big over sized unit, but which is the optimal size?

There's another web calculator:
