Thanks StarTech I'm intimate with head gaskets blowing through as I own a 31 ci intek! But didn't really give it a thought as I didn't think these were susceptible but will see how the compression looks just in case. I couldn't believe the racket the valves were making at 80 hours, when 160 came...

Thanks Tiger Small Engine Yes I'll investigate further before I consider rings, valve stem seals, oil rings, crankcase reed are a few things that come to mind. Whilst they recommend 300 hours, the rattle was that bad at 80 hours I couldn't stand it, amazingly quiet after setting them, at 160...

Torque/power curves here

726cc FR691V (651/691/730 FR/FS/FX) uses oil, anybody done a quick ring change and got away with it? Only 240 hours, not particularly happy about it, have needed to adjust the valves every 80 hours to stop them rattling their heads off. I'd like to think I could get away with a set of rings, but...

I have an FR691, FR and FS series have a single barrel carby, the FX series come with a two barrel carby with dual stage canister air cleaner. The 651, 691, 730 are all 726CC engines, roughly 21.5, 23 & 24hp in the FR series, the FX has a slight reduction in hp. Quite a few years ago I searched...

Put em the lathe and run a boring bar through them!

Lots to consider depending on your use and thickness of your wallet, most is personal choice. Bigger diameter wheels slightly smooth out bumps in rough ground, but in the scheme of things may not be particularly noticeable, 2800 and 3100 both have external oil filters for ease of maintenance.

I know it's advisable and necessary to use OEM parts in certain situations, and I'm not knocking the use of, but those B & S prices are criminal (like most OEM products LOL)!

Can't see it myself, which ones exactly, folks need to know if this is "actually" the case?

Nah, I think SpaceX has that covered. Good job on the install!

My 800mm lift floor jack does the job for what I need but at $80 it would sure make things easy for some folks.

Great, I'm sure someone down the track will get some good mileage out of that!

It's always nice for the OP to come back with a resolution to the question so when others in years to come search one of these engines/scenarios they glean some info, what was the outcome of shaft sizes and compatibility?

Yeah I need a better air cleaner

Yep, three shots should do it! LOL!
