Model T Ford Forum: Forum 2014: Air filter - starting
Top of pagePrevious messageNext messageBottom of page Link to this message  By Bud Holzschuh - Panama City, FL on Wednesday, January 15, 2014 - 11:00 am:

Foe the last several months I've noticed my 15 touring can be difficult to start.

Engine in excellent shape and coils recently checked. Carb is L2. Once started car runs like a dream.

And then I remembered all this started about the time I installed an air filter (typical - from Lang's)

Question is - has anyone else noticed a change in handcranking after installing this filter?

Maybe it needs a different procedure to catch on now like less choke or a different initial setting of the needle?

Bud, I have run one of those without problems.

Here's a cyclonic one I run on our 27 speedster.

I have a foam filter on my '26 Roadster. Started it the other day at 21*, no problem. Also no change in starting procedure. PK

Question 1: how does it start without the filter on?

I run a filter on mine and have not been able to tell any difference, except I do not worry so much about damage to my engine from dust.

I use one of Lang's foam air-filters. It breathes freely and near as I can tell, hasn't caused any difference in starting or acceleration (such as is possessed of a Model T). At the beginning of each driving season, I give it a spritz of oil and forget about it for another year. It's good product.

OK, problem must lie elsewhere and the addition of the air filter - just a coincidence.

Thanks for the reports.

Filter restricts air flow at running speeds. You lean to compensate. Then it's too lean for starting at cranking speed.

I agree with what Ralph said. If the filter has any serious restriction at all, it will run rich. Some Model A suppliers, I believe Snyder's is one, actually sell a Model
A carb that is tuned to run with a filter.
