1641 eng troubles

[Mcamp]

I just picked up a 1641 was told it was only running on one cyl. checked it out and fired it up with no air filter in it and the lid off the aircleaner,it runs good and sounds good took for a ride,turned on the 44in. deck and it has good power.Now the issue,i put a new air and prefilter on and it won't run,if i take the sealing plate off the filter it runs good,when running if i put the center plate on, it starts blowing oil into the air cleaner and dying almost instantly.What could the cause this problem? Thanks

Did you check out the crank case breather? Maybe the read valve is bad?

[Mcamp]

Thanks Sam, i'll try to check it out when i get some free time.

update: i replaced the breather and still had the same problem. I looked at the air filter and thought it looked funny, tried to blow through it and can't! new filter is junk the paper liner has a coating on it and won't let air through.Installed another filter and it runs ex.

That's interesting, wonder who made the bad air filter? Never had that issue.

Never heard of that before.
Glad your 1641 is up and running, I think you will like that machine. I really like mine.

Never heard of a coated air cleaner? What brand was it?

A new air cleaner and foam pre-cleaner is on my to-do list and I'll avoid the brand you discarded.

the air filter was from briggs.

Ouch! A Briggs air cleaner?

Never had that problem. Complain on Briggs' website.

Very interesting. Is this coating or covering something that can be seen? You have to wonder if the filter problem is result of manufacture, storage or sabotage.
