All the racing lawnmower forums are dead these days, I’m trying to determine if the crank, cam and lifters on briggs flathead 28 is interchangeable with the 28 ohv motor, all the info online is for flathead- maybe because of their class rules?

there is one comment I can find that suggests that it is, if this would be convenient as there is a billet flywheel, crank, cam, rod & piston available for the flathead motor and I have some ohv motors onhand. (The non avs early kind)

Trying to end up with a light weight air cooled 500cc vertical shaft motor that will do 5500-6000rpm for my amphibious boat thing, currently using a 200cc and it’s a little underpowered and it makes me nervous turning the pot metal flywheel so fast.

I guess the other way is to find out if the 28 flathead is common in nz, Shiloh?? I forgot your username to tag you!!

curious to see what happens with petrol light vehicles when rucs come in on all vehicles as promised by nat-act - putting the equivalent of another 90 cents per litre on top the rest of the fleet is going to be pretty unpalatable, i cant see how the cost per 1000km would vary much between the types?

the headlines good for stirring the antiev pot but i guess thats what we have in store?

boo

the big question is, there is a $23/1000km difference between ev and phev, liv does around 35k per year, which is $805

so what is the minimum amount of work you would accept to lvvta cert a leaf as a hybrid to get the cheaper rucs?

Mpw are highly regarded, there’s another guy a stones throw from there (malcolm) maclean metal spray who does the same sort of work who would be the more cost effective option for weld/spray/machine/assemble stuff 

Looking at the poster for this yesterday - its 10 year anniversary in October

i have enough bits to run victa bike, @rot808 had sachs bike running last time we spoke

we should probably make an effort to head down

has anyone been brave enough to buy a <$6k leaf specifically to put in stock for when the ev's enhanced battery becomes available?

i assume there will be a very short window where the economics of doing this are favourable but this would be a great combo to replace our runaround fleet with.

3700kw over 6 seconds?? is 6kwh? i had never considered how much fucking around we do for such a small amount of energy

i cant wrap my brain around that to the point that i think ive made a terrible error. feel free to heckle.

Do they take vband clamps with a wider vee groove? I don’t think the one on my exhaust is correct as it’s sitting up on the shoulder of the flange bit and looks uncomfortable 

excellent

so cool

The motors from early 90’s but only done a couple of hundred hours/religiously maintained as part of rescue fleet - nothing suggests crud but I will poke further to check 

What j5 said sounds sensible, I will just crack the stick a bit to break the vacuum and check next time - surprised this didn’t come in up when googling 

I made a video of it 

Can anyone explain a mystery why on a big old diesel motor if I pull the dipstick out after running it’s dry, but If immediately dip it again it’s full - like magic

its like there’s something hydrophobic (oilphobic???) on the stick after running

same deal if I shut it down and leave it until the next day, first check it’s dry, second and any subsequent checks it’s full

Wow cool 

does anyone know why small vertical shaft engines make so much less power than horizontal engines he same cc

do they grind the cams for lawnmower rpms?

Clint surely your a member of some industry associations and know how these things go 

please fill it full of french electrical problems joe

is that a snorkle under your seatpocket tori

if not john brooks then optibelt carry them in nz also

ive been proactive and prepped too far in advance and now there is enough time to break both bikes. 

cheeers

did you take that pic special?
