5hp tiller engine

[Thepartsguy]

I guess this is where I’ll start with this..
-gov removed internal/external
-Cam
-springs
-eyebrows shaved
-minor port cleanup
-header
-Heavily milled on billet cylinder head
-arc 6330 billet rod (shows up today)
-arc billet flywheel 30* advanced key
-electronic ignition

i’m not using the mikuni (more on that in a bit.

 

[Thepartsguy]

lets talk about the carburetor..
-generation 2 pulsa jet
-not sure what the throat is bored out to
-swirl port removed
-Throttle shaft filed thin
-throttle blade screw filed down
-linkage filed for true WOT
-pump block filed true
-choke removed entirely (stock appearing)
-double tank gasket
-massive shoulder by pump block filed out
-of course a full rebuild kit with seals

No explanation needed here

Got a sidecover that has the t/q mount and it’s tiller output so my welded tiller cam works perfect.. I’ll be using a 3/4 standard 30 series

 

[Thepartsguy]

Here is the sidecover I have purchased. No point in buying a sidecover if your not gonna get a gasket kit to set the crank end play.. don’t want the thing slipping around inside the case with the new rod!

 

[Thepartsguy]

Almost forgot to post a picture of the rod. as said above it shows up today..

Alright my question is… total cost. Also, where did you find that side cover? They’re like a pot of gold-they don’t exist! I’m joking about that they’re just hard to find.

i’ll have to login to a few different places to grab all the prices but the head was $100 the flywheel $165 the arc rod was $50 all in all to much probably. but from here on out it’s $22 rod bearing replacement or worst case another $50 rod. swap all parts onto another cheap 5hp and go.

i might have like 10 but theyre connected to things. ife you need one i might be able to hook you up!

 

[Thepartsguy]

I was surprised when I did a quick search and a like new side cover for $30 popped up. I snagged it immediately..

Thanks for the offer, one day I'll probably pick up a 5HP for the right price, but if I find a cheap, you might get a PM.

I live down the road from a machine shop that has been ran by the same family since the town started probably. he can torque the rod but also i’m gonna ask if he will throw the cam in the mill and lighten it up by carving material out of the gear. I’m going to take a chance and hope the cam isn’t big enough to send the lifter bore face to the moon. If it breaks it off i’ll have to have the next block reinforced..

Sounds nice. Here's hoping it stays together!

Oh I’m sure it will the enduro rods are said on the forums to do a little better on the dyno.. I really want to find methanol.. can’t believe no ones made a comment about the finless head and Heat yet..

 

[Thepartsguy]

The other forum board called it a 30 though deep trench left where I shaved off the eyebrows from the block and that would make compression so low you can’t mill the head enough to gain it back.. good thing this head is not only milled but also relieved and welded on. I’m almost sure I’m getting that compression back either way...

Sorry , Im a California guy,,,,,maybe that explains it ! Can't at all understand why a guy would put so much work and money into a flathead,
That's like Honda running an offenhauser at indy this year !.......sorry I just can't help myself. doesn't equate in my brain !

Da redflash

Ahh it's surely for fun. They're cool little engines and sometimes we like period pieces, but don't think you'll make near as much power as a clone!

Mike clements 5hp tiller engine pulled over 35hp on the dyno.. I feel kind of lucky to have got one of his cylinder heads.

 

[Thepartsguy]

Yupp my rod did in fact show up today.

Oh my. I bet you do feel lucky! Shiny parts! That always feels nice. We'll see how it holds up compared to your 8HPs.
