Nope,totally taking your advice and not going to mess with it at all. Brand new right out of the box will be how the engine will stay. Fiddling with and experimenting with an old engine is one thing, not a brand new ($$) one. I.m heeding your advice and keeping my warranty intact!

I also have a Snapper 33" Extra Tough RER that I have a 18 hp flathead twin2 on that works quite well. It was originally an 11hp. I had a 17.5hp on it but put it on my Husqvarna zero turn that oem was a 17.5. The AVS weights broke apart on it and trashed the engine on it.. It ain't the '60's...

I might add that the 11hp is the original factory engine,,not a '1960's' style hop-up. I agree,this isn't that era any more..

Thank you for that additional information,Born2mow. I actually have the choice of replacing the 11hp on the mower with a 10.5 or a 13.5hp,with the 13.5 actually being a bit less $.

Thank you. I have the intake and carb still on one of my bad engines that is a 17.5 Intek AVS. I am looking at a 13.5 Intek AVS,both are 500 cc engines. easy to swap the intake+carb. However,13.5hp most likely will be ok on the mower. 17.5 hp may have been overkill. Mower is a Snapper RER 30"...

I have looked at several 500 cc Briggs engines that have different hp ratings. the lower rated engines are also lower in price. I am repowering a smaller rider(30") and am wondering just where the extra horsepower comes from,with the same cc displacement. Compression,carb,what? TIA Sam

While I do use Super Tech (price point) most of the time,I will use other brands of OPE oil.no brand loyalty here. A high ranking person I know at Walmart has told me several times,Walmart absolutely will not tolerate customer complaints or returns for any item/product they sell. If 2 automotive...

Follow-up on the weak spark/coil issue. I got the new coil from Amazon,put it on and the engine fired right up,sounding better than it ever has. I went out and found the tallest grass I had around the yard and mowed for a half hour or so. I then restarted the engine several times while it was...

That is good info for me. I see on Amazon,they have the 590781 coil listed for a 42A 707,which is what I have. $15.00. Not a bad price,but a bit of a job getting to on this engine. Briggs didn't skimp on shrouding or number of bolts holding them on on this engine!

No,Shell Rotella straight 30W If you read the specs label,Rotella isn't recommended for gasoline(Spark) engines,but this is because the large amount of anti-wear additives ,mainly ZDDP,are not compatible with automobile engine catalytic converters. Modern car engines usually don't have flat...

I had a no start issue with the Twin 2 after it was up to running temperure after mowing for a half hour or so. It looked to me that the spark wasn't as hot as I thought it should be,as no spark that I could see. After it cooled overnight it fired right up,no problem. I mowed a bit and...

(Waaaay off from lawnmowers,but.....Back before I retired,a couple of the guys in the shop were bass fishermen. One was overheard to say,"I'm trading in my current outboard for a bigger one." The other guy asks,"Why?". First man says ,"I can't bust 100 MPH.". I thought to myself,"Man,those bass...

2 cycle usually,almost unlimited rpm.10,000 rpm isn't out of the question. Of course,Yamaha and Mercury are in a high 4 stroke horsepower competition now. 400+hp outboards are on the market right now. Of course,they come with a price tag that is HIGH also!! Still,I would have liked to have...

Thanks for the kudos! However,I'm way back in second place on this hop-up. I have looked and looked for the Snapper video that I saw a year or two ago with no luck. This guy put an outboard engine powerhead on a Snapper! As best as I can remember,it was 115hp Mercury outboard. It was...

If you look at my sort of jury-rigged muffler setup on the Snapper,the "chin" muffler works fine wired up the way I have it now. Two lengths of angle off the rear frame box will do away with the baling wire and look, well,morel finished. Just haven'y had the time or have gotten the angle iron...

Nope,it does not notice that clump of fescue! Of,course,the 17.5 Intek didn't either,but the opposed twin does seem to run smoother than the Intek single. That makes sense though,it's a naturally balanced design,unlike the Intek single that has all the extra parts to try to combat the inherent...

Not pressure-lubed. :-( As far as idling, as a matter of course, I run at recommended rpm,both for oiling and for cooling. I've read from many posters that poking around at low rpm hurts both the engine and the hydros. Briggs themselves,say let the governor do it's job and run at or near...

As I said in the previous post,2 different Intek AVS 17.5 singles have failed me,or should I say they broke themselves(and me,too,$$)! a couple of years ago,the first one ,for no good reason,snapped the head off a valve right above the stem and the head punched right through the piston. I bought...

Thanks for all the positive comments on the Briggs opposed 2 cylinder engine. I really wasn't wanting to spend major money on another Intek engine that seems to have inherent reliability issues. I know,I know,there are those that will sing their praises. That's ok with me,but I have had 2 that...

I have elected to swap the low hour (<24) Intek 17.5 that I have on my Snapper Extra Tough 33" onto the CZ42175 Zero Turn. It gets more use than the Snapper. The Intek will be a plug-and-play on the Husqvarna,as that's the same(broken) engine that's on it now. With that swap around in mind,the...

Thank you. Yes,indeed,the stators are the same size. The charge rate depends the magnet size in the flywheel. Thanks again!

Does anyone know if the flywheel and stator on the same horsepower size(19 HP Intek and Vanguard single cylinder) engines are the same? TIA

Good to hear. I have had it running on the workbench and the integral carb fuel pump had no trouble picking up fuel from the small can of gas 8 inches or so below it. I ran fuel stabilizer through it and then ran it dry before oiling the cylinders and squirreling it away. It never gave me a...

Thank you. The twin does run so very smooth here on the bench. I believe anything it would require to put it on the ztr would be totally reversible,should I wish to go to a more 'modern' engine in the future.

It's a splash lubed,alas not pressure lubed. No filter,of course,either. A comparable new pressure-lubed single similar to what is on the mower now is around $600+ or so. The Husqvarna has been and is still a good solid mower that does all I require from a ztr,so I'm going to keep it no matter...

Hello all, I have a Husqvarna c42175 zero turn mower with a 17.5 Briggs Intek AVS single cylinder engine on it. It's a 2005 and the engine runs fine but is beginning to smoke a bit and it has a lot of hours on it. I have 18hp Briggs I/C opposed 2 cylinder from a previous lawn tractor type...
