Glad to blow a hole in the case.

[sparkwizard]

I wonder about all those center punch marks around the gasket surface on the case.
Maybe it had a history of blowing gaskets?

Depending on the length of the pull rope it looks like it could be used as a retractable boat anchor.

The crank is much much stronger then the rod and a lot of that could be transferred from the rod itself. be carful and find some muriatic acid. might shine up like a mirror. others say they have awesome success on all kinds of different cranks.

Crank is junk. Markings on rod beam have Briggs marking. She's a stocker but she sure ain't a rocker. You can put an epoxy on engine and glue a metal patch over the new crankcase vent or make a bolted patch to cover the hole. I'd scrap it and keep it as a man cave decoration and build another motor. Not like it's a rare or special block either way. Why run the risk of crank centers or cam journal centerline knocked off axis by previous damage.

. You pointed out some issues I’d hate to deal with. I think you’re right: junk it. I was starting to add up the cost of parts!

Does the wear on the crank where rod attaches look excessive? View attachment 303891 View attachment 303892 View attachment 303892

Honestly, the crank journal looks pretty worn and scratched up. Would have to look up the spec on what it should measure at then take a micrometer to it to see if it could be saved with wet/dry sand paper but it looks like it's too far gone just from the picture. May be time to hunt down a $50 marketplace special.

There is a 50 dollar HONDA Flathead 3.5 on ebay.

5 horse briggs all day long.

I’m probably going to build another clone. I’m not really huge fan of flatheads. It was on my Powell. Not sure yet.

Decor it will become! Actually inside parts are pretty cool looking.

How's the bore?

The bore seemed fine, but I think I’m done with this engine. It’s served me well

Picture taken in 2006. So I got 17 years out of this souped up racing engine. I was told and believed. Hahaha on me.

 

[Augiedoggie]

Got your money's worth I reckon. If you don't mind a suggestion, put a predator on it and ride it like it owes you money

Now we‘re talking. How can I not?

 

[Augiedoggie]

Flathead definitely has the cool factor but if you just want a runner to ride for shits and giggles just slap a predator ghost on there and you'll be smiling like happy hour at the whorehouse

 

[Minimichael]

Yeah but you wanna look cool doing it... I say buy another Briggs 5hp if you can. You already know what you're working with, and it'll swap right in.

 

[sparkwizard]

Another vote for a flathead, since nobody asked.

I don't need to decide which engine.

Yeah...me too.

 

[Minimichael]

Mr. Pink's got it right. Set the clone aside for your next bike.

Cool is good. How much fab for Predator I wonder?
