Echo cs 8000

[Billy Currie]

I'm not sure of its age. It was flooded in hurricane Matthew. When I got to it the crank bearings were rusted. Saw was locked up from corrosion. Cases were pitted pretty bad but salvageable. I had an intake welded to it to run a HL series Tillotson, its temperamental. The last time I messed with it, I could not get it to start. I will drag it out and have a look at it over the weekend. I don't have many pictures, I think I have a short video of it idling.

I tried to load the video, no go, after it loaded it said an error had occurred and the file was missing something.

Any porting?

I have one that will prolly get an hl carb may even try a reed block.

Your Impulse through the block?

 

[Billy Currie]

I am using the pulse in the case, pulse on the carb is blocked and a nipple is added on the side of the carb. Porting: exhaust is raised to somewhere around 88, transfer s are around 122, intake I don't remember what I did with. I think it's close to stock, around 80.

Ignition is what I think is holding me back, rev limited.

Not thinking the ignition is limited. This 8000 hit 15k today

Probably be fun with a pipe on it.

That is something that would be fun to adjust the intake length on to see what results can be had.

I'm thinking an 048 piston may be the ticket...

181 is too short.

13mm pin 52mm bore.

If anyone has some other options I'm listening.

Dolmar 9010 piston

 

[Billy Currie]

15,000? I'm not sure what mine is turning, no tach. It could be the carb giving me a fit, I will try it again, but a head is coming for sure.

I looked at those, but found conflicting reports on pin size. Some say 12mm some say 13...

It hit it briefly but wasn't rich enough for my liking. Didn't notice a limiter if any sort.

460,272,372BB are others

Yeh but I'm looking for 13mm pin. Might try a conversion bearing on the rod end....

Some 13mm pins have thinner bearings than the 12mm ones. Just a lot of trial and error. The wrist pin on 660 and 288 are different but the bearings make up the difference

I can send you one. 13mm I am 98% sure

Nice build write up! I'll bring my 7900 over for a side by side when you get back.
