Question is.... With new seat, can I just put fuel line straight to carb again (as in, will the new seat compensate for the crazy pressure? ) and eliminate the 't' I have in the fuel line?
Fuel pump... New walbro.
Thinking it was actually lack of fuel now. Pump originally had way too much pressure and kept overflowing carb so I split fuel line and ran half back to tank... Worked mint but maybe just not enough now for the high side rpm..
Edit: just ordered new needle and seat...
Thanks for the chart... Ordered aluminum weight and some white springs.
Now... Took it for a spin down the trail.... Finally get it up to speed at prob around 5000rom and it starts to sputter and bog and die. First time ive had it on long enough straight to get some speed. Was a pita to get...
Not positive but believe it's red spring on tightest setting.?? Spring might be from a knock off as I can't find much for red spring.
I read a bit about weights to delay engagement? These replace the 'buttons'?
Or garter springs change engagement as well? Don't know much about these tbh
That cam looks real nice, but I'm not spending more money on... Wife has had enough of my 'hobby' cost... should I change to a 24 tooth to change ratio to 9.6 so I hit powerband sooner? Or jump to a 26 tooth to jump to a 10.4 ratio? That's a quick easy change
I read that every extra tooth on sprocket will need 200rpm to gain same top speed?
Currently, have 10 sprocket off motor, 20 in jackshaft, 10 out and 40 on axle.. So..... 8.0 ratio.
Does 65 at 5000rpm...

May give it a shot yet. Simple to change the chain and sprocket on the jackshaft. But it defeats the purpose as I needed/wanted higher road speed than my 5000rpm gx270 gave me.
It is technically over the rated hp, but I have yet to wear out a belt on the tav30 with the modified gx270 and I've gone in and through some pretty gnarly stuff with. I don't put a lot of weight on the 'rated' hp for these anymore. Gearing is a huge part of it and my kart is geared the sweet...
Both using same gearing and torque convertors yes. Literally just motor swap. My problem is I now know I overestimated what to expect and also forgot I had my gx270 already modded (filter/header/jetted gx390 carb/ported and polished) so of course it wouldn't be as torquey.
Where can I find a...
Thinking of putting it back on the kart and tossing the spare flatside mikuni I have.
I must have had too high expectation... More I think about it, I must've been dreaming as my 270 had filter, header, Port and polish and gx390 carb on it. Was most likely putting out 11hp already and better...
