New pulleys welded to hubs and primed.


Look at that super ground clearance!


Hood off to get to the jackshaft easier. First time the hood has been off since I bolted it on for haspin 2016.


Haspin dust from 2016 still on top of the engine.


Top of hood will get repainted. Hood rack removed for welding in more supports and shovel bracket.


Old jackshaft finally removed.


Had a clearance issue with the new pulleys. Old jackshaft in the vice to hold one of the new pulleys while I trim the hub down.


Cut most of the way around.


Cut finished, about 1/4" removed from the hub.


Pulley now lines up where it belongs and clears the side cover.


Testing out the anti mess oil drain for the first time.


Works perfect, no oil on the frame or anything else.


The oil had some aluminum sparkles and also some aluminum flecks in it. Engine still sounds good, so not sure where that came from. Looking for a spare engine to build anyway to have on hand for trips. Started the engine today and it still runs good after sitting for awhile. More updates soon.

Looks good! If the little Briggs gives out you can always find one of the big block 16hp singles!

Looking good mr. mod! It looks like the jackshaft fits in there pretty snug.

Thanks guys. The 10-11hp briggs flathead will fit the mounting bolts the same and I think the crank output is the same 1" size too. But the engine is a bit bigger and I don't know it it would clear the hood. The engine that's in it now has had a lot of use before I got it. Came off a walk behind mower, same guy owned it since new. Doesn't smoke much or anything though, so we'll see.

It could use more horsepower for sure, the alternator takes a lot to turn if the battery gets low for one thing. This won't stop you from getting home though since I can turn the alternator off and the engine will run without the battery. In some situations, such as when trying to get up a rock ledge or a log, you have dump the clutch to try to ram over it. With the jackshaft acting like a heavy flywheel, it's slow to get everything turning. That sort of limits you sometimes. Not sure a larger engine would help too much, maybe a little. The flywheel effect helps to keep the momentum up for going up hills and things with the smaller engine so it's a trade off. Over all I'm happy with it, gets the job done and I can always find engine parts easily. Also, bringing an entire spare engine somewhere is not as much of a big deal as it would be with an opposed or a v twin. The 8hp is smaller and easier to move around. I think easier to work on too. And anyway, my main goal was to cut back on fuel consumption when I first started building it.

I still need to take it on a long test run. I want to try to get from my house to the garage I work at via an abandoned rail road line. I've been through there a lot of times with a motorcycle so I know the route pretty good. The trip would be about 20 miles. The main issue is getting from my house to the start of the tracks, there's maybe a mile or two separation there that would be tough. Maybe I could just get dropped off at the tracks and be on my own from there.
