clutch and tires and more

[ed1380]

i finaly got the engine running and semi tuned up.

i found these (http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=47638) tires on HF, and the axle size matches up.
would that wheel work? or is it not rated for enough speed?




2nd question. what gearing ratio should i get. ive heard that 6:1 is a nice middle. so thatd be a 12 gear clutch and a 72 gear sprocket.
would that work or will the sprocket be too big?
is northern tool the best place for sprocket and clutch and chain?


3rd question. would this work for mounting the sprocket? no brakes for right now. http://i43.photobucket.com/albums/e398/RussianCommy/P1030093Medium.jpg


4rth question. anyone know the HP rating of this motor? looks like a flathead briggs with a bowl carb

1. Those tires might be ok, i dont see why not.
2.I'd do a 12/60 that will be good with those tires,and yes northern is great.
3.Try to find sprocket measurements at nt and go from there or bring the hub to northern and try to find a sprocket that matches up.
4.Dont know hp rating, but its a Tecumseh

[Russ2251]

It is Tecumseh. Look for numbers stamped on top, front or rear of blower housing. This will give you engine size. H35 for example.

[ironman]

do not do not buy those harbor frieght rim tire combos they are junk busted 2 tires in one day.never again now if its for a little kid in the grass they would be fine.

[ed1380]

IDk about little kid in grass, but should be under 250lb for kart and driver, and its going to be mainly on packed dirt.

havent seen any stamped numbers on it. I'll look closer later

[Russ2251]

havent seen any stamped numbers on it. I'll look closer laterMay be difficult to see...but it is there. Do you have pic of pto?

[ed1380]

nope. maybe its under the tank, but i dont remember there being anything under there.

heres the pic

[Russ2251]

This is direct from manual.

[ed1380]

i found a code where teh fuel tank is supposed to be, but it was rusted bad, so i rubbed it a bit and its worse now. :oops:
all i can make out now is GER


well the needle in the carb thats connected to the float is sticking. the needle is pushing into an o-ring, but ive never seen that. usually it just pushes into metal.

is that normal or can i remove the o-ring and bend the float back to normal?

[I like karts]

To find the numbver on the engine, put a little white-out stuff on the numbers. It fills in the grooves so you can see it better

[Russ2251]

float is sticking. the needle is pushing into an o-ring, but ive never seen that. usually it just pushes into metal.I've seen both. What you probably have is a Viton 'O' ring. They break down after time due to ethanol in gasoline. To combat the alcohol problem engineers have come up with a material called 'New' Viton which is more tolerant to additives.
is that normal or can i remove the o-ring and bend the float back to normal?Not normal. Chances are that it will not seal and is likely that you could not bend tang on float enough to make up for missing 'O' ring. To be done properly, get a carb kit. Pretty cheap and carb will be like new.

[ed1380]

i found out the engine code. hh60-105101f-if GER 629d

I'm guessing 6hp. not bad.

turns out the generator i have out back has a 8hp tecumseh on it. too bad the rod flew and busted the block and head

[Russ2251]

Something you might want to try. 8hp carb just may fit and work on 6hp. Worth a try.
2 through 7 hp carbs are all basically the save size venturi.
8 through 12hp used a slightly larger venturi allowing them to breath better. Just might be swappable and may (?) yield increased power.
If engine lags in transition from low to high rpm (under load) then engine is running too lean. Possible to adjust it out. If adjust doesn't work, then carb is too large and will have to switch back to original.

[ed1380]

maybe, b ut the 8hp carb has lots of corrosion. i'll have to take a look inside, but thats for another day

[ed1380]

inside its even worse. about half a teaspoon of corroded aluminum in the bowl. and its needle was also sticking. so i kept my carb.

sunnova***** it getting on my nerves. w/o air filter i can get it to run pretty good. but w/ the filter it only idles. touching throttle kills it. adjusting needles doesnt help.

[Russ2251]

Make sure filter is clean and not interfering with choke butterfly or linkage upon assembly.
Could be stuck ball check (internal). Difficult (if not impossible) to clear unless completely disassembled. Carb cleaners may or may not work. Might be better off looking for a good used carb. Tecumseh carbs are notoriously problematic even when properly maintained.
One of my mowers suffers with a stuck float/needle valve every spring. Sometimes a good knock with a small plastic mallet clears it. It appears this is not the problem with yours.
If you do get a new/used carb, make sure it is not an emissions type. Must have high and low speed adjustments.
Check gaskets for leaks.

[ed1380]

ball check?

the needle sticks all the time. ive cleaned it, even cycled it in and out a couple hundred times. might have helped it a bit.

hopefully the clutch wont engage at too low of rpms.

do tecumseh have a problem w/ the recoil starter. cause on the inside mine unscrews all the time.

[ed1380]

wheres the cheapest place to get the clutch chain sprocket. ebay no because shipping sucks.
northern has the cheapest sprocket and chain i can find.

[I like karts]

Clutch (http://www.mfgsupply.com/GoMiniClutchCent.html/mv_session_id=gs7sjKMM)

Oh and btw about your gear ratio question, I usually go with 5:1 as a standard (10t clutch 54t axle) it gives more grouncd clearance and speed. 6:1 you will have insane acceleration, but you won't get going very fast

[ed1380]

local shop got a clutch for $29 im gonna get that
chain is $10 for 3 ft
$12 for a sprocket thats too big for my tires. smaller ones are only online. maybe later ill drive up to northern tool.
since i dont have a large selection of clutch and sprockets its most likely going to be a 5:1

thanks guys. ill get videos whenever

[ed1380]

got it together. took it for a spin today.
less than 250lb + 6.5hp + bumpy yard - brakes = one hell of a fun machine thats hard to control
pics later

[ed1380]

heres the pics. it rained last night

[kibble]

That sort of terrain looks like a blast! Is that rod supposed to be bent up in the front?

[oscaryu1]

Probably it was too long and he didn't want to cut it.

Either way, looks sweet! What type of motor is that?

[ed1380]

yeah it was too long and bending it helped clear the little bumper up front. the whole backyard is like that except a little sloped and the rain makes gulleys. which = no fun. lol

its a tecumseh. stupid thing wont run right w/ an air filter

[kibble]

Ooh..... so you're running it out there without an air filter?

[ed1380]

took a couple laps yeah. now im trying diferent approaces. maybe a real long air filter box so the air is less turbulent after the filter.

[kibble]

I'm wondering if any damage was done to the engine, particularly being in a dusty looking environment like that.

[Kenny_McCormic]

Yea, that filter is way to small. Engine wouldnt take any damage so long as it was breathing filtered air.

[ed1380]

o but it wasnt lol. i dont really care. it wasnt long enough to do much

[oscaryu1]

In that condition, 15 minutes would have been enough to score the cylinder heavily. Any longer? Wiped out the rings and who knows what else...

And me being a guy who tore down a Briggs 3 horse with no filter for 1 month. The cylinder on it was in worse condition than a 2HP's with the rings installed upside down.

[ed1380]

i dont think ive ever riden longer than 5 minutes straight on any gokart

upside down rings. wow who did that? :D

[Russ2251]

Upside down rings shouldn't cause anything worse than compression loss and oil control problems especially if top ring is semi-keystone.

[oscaryu1]

Upside down rings shouldn't cause anything worse than compression loss and oil control problems especially if top ring is semi-keystone.

Friend did :ack2: I took it apart to replace the pan gasket... and did I find? LOTS of metal shavings. Took the piston out. Metal bits in the rings, on the rings, in between the rings...

[Russ2251]

Probably ring end gap is culprit.

[ed1380]

russ do you think distance from air filter to throttle valve maters for proper air/fuel mixing

[Russ2251]

No difference. However, problems can occur if intake pipe (manifold) is too long (excessive distance carb to engine).

[ed1380]

k well that problem got fixed. now it works w/ an air filter. that thing flies. i need more room. i came in w/ dirt in places i didnt know i had :roflol:

[ed1380]

little update. the rod is in engine heaven. i was warming it up and BANG. bang.. bang...bang....bang....dead

if the aftermarket rods are really $20 then ill get one. so thats where ill need your help guys. are the rods for 5hp briggs and 6hp tecumsehs the same? i dont know which rod to get

[jr dragster Tyler]

HA HA HA HA BYE BYE rod! If it broke under warming up then thats a tired motor. And if you heard BANG bang bang then I think you might need to replace a bit more than the conecting rod!

[Russ2251]

are the rods for 5hp briggs and 6hp tecumsehs the same?NO!!!

[ed1380]

yeah haha bye bye rod

the bang bang was the crank hitting the rod while spinning down. yeah piston skirt got some damage too.

ok russ i got you ill search for a tecumseh rod

now where do i search? i can only find crappy oem rods. i want one so i can run ungoverned w/ no fear
