home for a few days, started putting the engine back together.
Got the crank back from balancing + new bearings + welding


Got everything put back together, 90 carbs are on - had to cut the tray to accomodate the deeper bowls.


Going to get the floorboards back in tomorrow and try get the engine going

Nice, shame the nose cone is painted, would look mint in carbon.
What engine you going for?

Designed some stacks, I've ordered a set and depending how they go I may start selling sets.






They are quite short as there isn't too much room with the 90hp carbs.

I've also designed stacks for tohatsu 50's

Yeah, you can see the weave through the paint. Am looking at getting it wrapped or dipped in a carbon effect.

Going for a 50hp tohatsu and just planning on doing some mild tuning, may race it so will keep it race legal.

Went out for a spin today after adjusting the mixture to help with low down. Ran a lot better, topped out at 54.7 knots with th 21g cleaver. Took the main jets out and replaced them with the 160's. Using small drill bits for reference:
165 = 1.65mm
160 = 1.85mm

So I'd guess the 160's have maybe been drilled out at some point, they were in the 90 carbs which I got from a racing guy. Still need to try it again with these jets. Also need to smooth the intake on the reed block, there is a slight step between the carbs and the reed block.

ran terribly with the 1.85mm jets... Idle has dropped about 200rpm, acceleration seems much better but doesn't go. Also found one of the carb gaskets was torn, I think it was probably while I was removing the carb as the engine was running fine. I replaced it when I swapped the jets over
I guess I need around 1.7mm or 1.75mm jets?
