Looks good! Sucks they didn't have the exhaust done but good to know they are taking their time to confirm it's right!

Yep! always better to get it done right the first time!

Looks pretty basic....... but as long as it works that's all that counts right
Few steps close

Yep, I purposefully made it basic so its really easy to replicate and doesn't take long ? getting closer ?

Good thinking

can i get sum opinions here? i want to swap the WJ71 (19MM) out for a tillitson 26MM HL324a, i don't expect anyone to know what that is lol, but im worried that the wj71 will not flow enough fuel as ill be running e85 and later on methanol (for them big gains lol) which need alot more fuel. what do u think? the tillitson is only 15 bucks (it is a clone/rebrand but ive read that they are just as good with a tiny bit of work) and i could sell the WJ for the same 40 usd i bought it for as its brand new. or should i just run it with the wj71 and see how it goes and change if i need to?

?I would buy both to save time. I would try them both. Your only talking $55. Would suck to find out the 1 you chose to try wouldn't work with your setup then have to wait for the other.

True. I think I'll get both and try. And its not actually $55, you can buy take-off ones from a stihl saw for very cheap, like less than $20 so I think, why not! Currently my intake manifold is being drilled for the wj71, so I'll try that first, then if it sucks then I'll re drill it for the tillotson. ?

Got me pipe cut up, here, looks pretty bad because the paint and all of that but once I paint it or Polish it (probobly polish) it should look nice ? I'll have to get one of them tgn long and skinny filter (don't get me started on long and skinny things ??) because the shortstack uni filter is too tall but it's here.



It's HUGE! lol
If I do have heat issues I'll do something like bonehead rc did with his

yep! I'm also liking the progress ?? Tomorrow I'm going to call HobbyTown to see if they can give me a rough estimate on the thickness of a flywheel I think I might be able to use. If it's correct I'll run over there and pick it up ? and then hopefully go to the machine shop next Thursday for (hopefully) the last time ?

Looks like the real deal with the carb on

Hey Z isn't that a Reed case motor? Where's your reed block?

It's the black thing Behind the intake manifold


Don't mind the Philips scew on the crankcase, it's just to hold the case together. And NO I didn't cross thread it, it was the correct thread type.
