G'day All!

I have scored a Rover 45 Select with a 91202 B&S on it.

The air valve that comes from the Carby to the engine proper is connected by a tube with rubber grommets.

These rubber grommets are degraded enough that air is escaping from them - i can tape some of it up but i can tell they are still leaking.

Will this affect things dramatically as the motor is currently not idling or running well at all.
How do i tinker with the carby / throttle settings to get it running a little better than it is without pulling the carby completely apart?

Thanks folks!

RG

First we need the model along with the type numbers of the engine. You provide the model but abut 100 different versions of this engine.

Second I think you are referring to the breather tube grommets. Those don't affect the carburetor performance much. Now if this engine has a metal gas tank than it likely one of the root causes of the carburetor problems. There is a fuel well that tends to rust out along with the tank itself getting very rusty. Usually this requires replacing the tank. the problem here is that Briggs quit making the tanks or at least they did here in the states.

Hey AVB thanks for the prompt reply.

On the engine plate it says it is a Type - 1384 E1 with a Code of 050823
Yes breather tube was the word i was looking for - these grommets are split and/or barely holding on.
I hope this helps - The tank is definitely metal but does not 'appear' overly rusty when I peer in or on the outside.

My understanding is i cant adjust the fuel mix on these through some reading but i am not entirely sure. I have also seen the carby diaphragm will often need replacing also.
I don't think the engine is in that bad a condition or old to have the real bad problems i have seen on youtube.

I can see one screw which appears to adjust carby fuel intake or similar but as i screw it out we seem to get quite rough - i cant screw it in anymore either.

Hello AVB and Argy Bargy,
I saw a YouTube video from the UK and IIRC he said 90% of the time it's the diaphragm that causes running problems (apart from obviously dirty carby throat and dirty air filter).


Ahh, if only victa had kept producing the thumblatch catcher series, they would be in better shape today!

Another problem is I can’t seem to get the revs up enough and very little disparity between highest and lowest revs.

With any rust I would check checking for clogged filter screens. One the fuel pickup tube and if you are lucky one on the carburetor tower in the tank reservoir cup.

As the idle screw the IPL does shows it to a fixed jet. And as Mowerfreak mention the fuel pump diaphragm does usually need replacing.

As for rpms problem it might be that someone installed the wrong governor spring. Note there two listed on the IPL and they don't say what the differences are.
